what about using small (pointlike) and stronger gamma source, or using some rock and collimate its rays using pinhole in some lead plate or using lead cyllinder+some shielding for rest of radiation so rays that are aiming a target not much prependicular to it will be just absorbed by cyllinder and they will not blur resulting picture? Or you could make a thinner slice of the mouse and put a source on it, maybe the closer is source and target to a photo the less blurring...
yeah, a collimator would be a good idea. that's how they do it in nuclear medicine, too... then again, that's very hard to DIY, as lead is a seriously annoying material to work with. it's soft and possible to cut easily, but drilling holes into it is a right b*tch. would have to melt it and cast it into a collimator form...
because of radon in the decay chain. it's radon is a radioactive noble gas and thus, capable of "moving". radon itself is radioactive, too. thus, the daughter nuclides get trapped in the activated carbon. watch?v=gN_b-rmq1c4
cool, i live in Japan, near Tokyo. I am trying to get a geiger counter. i don't trust the government over here. anyone know where I can get one that will test the air?
well, you can, for example, get them on ebay - then again, i really dont know how well postal services work after the incidents in your country. i have no idea which shops might sell geiger counters in your country; but e.g. old "civil defense" equipment from the USA / canada is quite crude, but a cheap and sufficiently reliable way to measure increased radiation.
good luck and courage to you! i hope the wind will blow the fallout to the sea again.
rats are much bigger and have a longer naked tail relative to the body, and they're REALLY different... like, they dont stink. yes, rats (and e.g. gerbils) dont stink, but the common house mouse has a horrible stench. rats in a clean cage will smell lovely of fresh hay.
also, rats are INCREDIBLY intelligent, being able to solve difficult tasks (search for some videos here; they can even be trained to come upon call etc, like dogs), while mice are rather dull.
@bionerd23 i have 7 pet rats and i teach them twice a day how to play rat ball (rats fight over a golf ball sized woofle ball and jump through hoops) and they are so good at it! they smell like freshly baked tortillas to me
Never the less, these picture look awesome. Please, tell me you scanned them In high resolution so we can use them as computer background. They look like a nebula ^^
well, sorta ;) - they're on my flickr, and the link to that is on my channel page as "Website:". just search for "autoradiography" on my photostream, and you'll find some of the photos.
haha, nah. maybe my hands got 1% of what you'd get when you get a dental x-ray. maybe 0.0001 rad. i dont have anything that could cause a significant health risk. however, radioactivity is highly overrated within the general population, so everybody assumes that when there's a trefoil on something, it's gonna kill you.

5/5! Awesome! It looks as though the Pitchblende and the baby mouse turned out the best! It's blurred some, but that's because radiation scatters in all directions from the source. It's beautiful! You could really make some nice artwork from radioactive materials, and it's quite safe too. Some people think radiation is like an "apparition" or "cloud" that's out to get them... lol... IMO, it's like a light bulb, only, you don't "see" the light, and certain light bulbs have different energies. ;)
yup, that's why one uses collimators in professional appliances / medicine - to prevent the scattered "stray radiation" to cause a blurry picture. =)
but, your comparison to a light bulb would only be applicable to an x-ray source, i think. remember that sources with radionuclides cannot be switched off... also, there is some stuff (like uranium ore) that actually produces a "radioactive cloud" - or more like, radioactive gas, radon.
You can build a homemade x-ray machine too. I'd be interested in seeing how that would work with polaroid film. There's videos here on YouTube about homemade x ray machines.
that is likely to play a role, too; but as not even a blurry bone structure can be seen, i suppose i'd need more / higher energy rays - but also a less diffuse source, probably, that's right.

Falls du Interesse an alten (gut erhaltenen) Civil Defense Geigerzählern hast, lass es mich wissen. Hab noch diverse CDV-700 (Geiger Mueller ), CDV 715 (Ion Chamber)
we do not use it anymore, as installing ionising smoke detectors is no longer legal for new buildings / installations. however, just having an old smoke detector at home is not illegal afaik - never heard it would be, anyway.
how is it the radium watch would do anything at all? radium only emits alpha particles, which would easily be shielded by the glass and metal on the watch. alpha particles can be shielded by a sheet of paper!
radium decays by emitting an alpha particle, that is true - but it doesnt decay into nothing. radium 226 decays into radon 222 -> polonium 218 -> lead 214 -> bismuth 214 -> polonium 214 -> lead 210 -> bismuth 210 -> polonium 210-> stable lead 210.
you can see there are a lot of beta decays in that decay chain, as the mass number does not change (electron emission). if its an alpha decay (2 protons, 2 neutrons), the core loses those, changing the mass number to -4 of the previous radioisotope.
also, there is quite a few - especially hard - gamma radiation from radium's daughter nuclides, as a lot of the decay products will be in an excited state, thus, immediately emitting a gamma quantum after decay to lose the excess energy.
see my "autoradiography - radioactivity on polaroid" video, by the way; i put some radium watch hands on the polaroid pack there, and they did illuminate the film.
You said beta, cæsium, radium, and uranium wrong. Then again it's illiterate Commonwealth's fault, who can't speak Latin /or/ English. And I would shorten "hundred and" tom "hund".
Now that's a damn nice collection of radioactive materials. The only radioactive material I've ever seen in real life was some uranium pellets (usually used as nuclear fuel in nuclear power plants), although I don't know for sure if they were "real" uranium pellets - I can't afford a gamma-scout like yours ;) - , they did look like the pictures of uranium fuel I've seen on the internet though.
P.S.: I DON'T wanna know where you got those dead mice from :P
Wow, you have a very strange hobby.... that seems sooo unsafe doing all these things in your home. You don't have any kids or plan to have any, will you? Do you think about the safety hazards carefully? I wouldn't want to visit your "laboratory".
nope, i do not have / want any kids and i dont have any pets either. i take care that nobody gets in touch with stuff from my "lab" accidentally. while i may do whatever i want to my own body, i know that it is my responsibility not to put others in dangers with what i do.
the problem with your blurry radiographs is the sources are much too close to the subject and the radiation is too diffuse. take the dead mouse and put it on your setup normally, then take your Sr source (looks like it's the brightest) and suspend it 10-15cm over the mouse/polaroid setup. give it several days to expose (3-4?) before developing. the further away you put the source the more point like it will be and the sharper the shadowgraph will be but also the longer the exposure will need be
thanks a lot of that tip! it sounds pretty plausible, that. the only problem is the amount of time needed for the exposure... i think it would need a week with this weak source. polaroids dont like freezers, but i guess it'd be ok in a tupperware in the fridge. i could just tape the source to the tupperware's lid, too - that should work and not get too messy. i think i'll try this next time i do an autoradiography - again, thanks a lot for the tip!
Aw man :(. Oh well i guess part of being a scientist is learning to live with a number of failures. I'm surprised that the uranium ore didn't yeild any interesting results...i guess i always figured that it put out more gamma than it appeared to have. Oh well.
Hey maybe if you could steal a speck of plutonium from your local government.... :)
dont worry about it - it was a rather certain thing to happen. ;-)
the welding rods only contain 2% thorium OXIDE, and also, a lot of the alpha rays emitted by it will be shielded by the tungsten it is encased into. yet, it's a great item for my collection, because i'd like a sample of every industrial / household appliance that contains radioactive material, so thanks for the tip anyway!
I'm thinking maybe the pitchblend on top of the baby rodent was too large, and because the radiation source was just too diffuse, that it washed out the fine details like bones? The smaller the light source, the sharper of an image you can get, so maybe using the Barium or a pure gamma emitter and exposing for 24/48 hrs might make bones visible. The coal radiation might've been washed out from the rad of the other big pitchblende. Great video as always! =)
thanks for your thoughts on this - yeah, well, the exposure on the mouse's hand / feet was surely too long, as you can see - its but a blot. but, if i place the source discs on top of a grown mouse's body (and let them expose for 24 hrs as well), maybe it'd work... i may try this, but i seriously have my doubts, as mentioned in the video.
in theory, any amount of ionising radiation MAY induce mutation and cancer. the more radiation, the more of a chance for cancer.
the amount i am handling is far too low to be clearly identified as a cause of cancer, though; you'd have to use much, much higher doses for a high probability of developing cancer due to the exposure to ionising radiation (as there are a lot of other factors that can cause cancer, too).
i thought it may be too thick to x-ray the whole thing... then again - considering the results - maybe not. i may retry it with a whole mouse, just for fun. =)
radium wurde frueher (um 1950) als leuchtstoff verwendet... denn als das radium noch 'frisch' war, hat es wunderbar gruen geleuchtet. die leute wussten damals noch nicht, was fuer einer gefahr sie sich aussetzen... und viele arbeiterinnen, die die uhren bemalt haben - die sogenannten 'radium girls' - sind durch den umgang mit radium gestorben.
nee, ich fress das zeug ja nicht... und wenn, dann waere ich ja auch ein 'radium girl' und kein 'radium boy'. ;-)
die halbwertszeit ist noch nicht abgelaufen; radium hat eine HWZ von 1590 jahren. das zeug dunkelt nur irgendwie innerhalb von jahren (zumindest an der luft, d.h. wenn nicht im vakuum oder unter argon) nach, so dass es seine leuchtkraft verliert... wenn man die uhr mit UV-licht anstrahlt, dann leuchtet sie aber immernoch knallgruen. =)
yup... ich denke, daran liegt das. weiss ich nicht zu 100%, aber ich denke es mir mal so... passiert ja auch mit anderen dingen, z.b. blei wird ja auch massiv vom sauerstoff attackiert... nach einiger zeit wird das extrem silbrig glaenzende metall daher so grau und stumpf, wie man es ueblicherweise kennt.
hmmm... soviel ich weiss ist patina (die sich auf kupfer bildet, das gruenliche zeug da) kein oder zumindest kein reines oxidationsprodukt... waehrend die graue schicht auf blei definitiv eine oxidschicht ist.
auf meinem 'fusion 2008' video z.b. kannst du mich aber auch sehen UND hoeren (bei irgendwas knapp ueber 2 minuten), dann siehst du, dass die stimme zu einer frau gehoert... =)
naja... obwohl... genetisch und koerperlich bin ich ne frau, aber die stimme und das gehirn hab ich von nem mann, deswegen sage ich oft 'ich bin ein schwuler mann in einem frauenkoerper'. ^_^
btw i´m makng research about getting strontium out of strontium chloride -> stable strontium metal. Im´going to put it in an ampule just like i did with lithium
btw: oh wow the thorianite is actually really tiny... i thought it was about 4 times as big...
btw RIP mice (yes otherwise they would have been eaten by snakes, i know)
LOL @ for a proper X-ray you will have to use X-rays
yeah, i'm still alive - i'm just quite busy lately and only have time to experiment on weekends, which is rather sad. :-(
interesting idea about the strontium, i'm curie-ous about the results of your experiment, as usual!
and... i will one day buy and run an x-ray tube, but it'll be a while until i can do that... need time and knowledge for it, as it'd be really dangerous otherwise.
that´s funny... i already did some research about X-ray tubes... they are actually quite safe if you just switch them on for a few seconds (maybe shield the rays that don´t go the right way with lead and it SHOULD be ok)
well, an x-ray is taken in... what, 100ms? and you usually receive doses up to 200 uSv, depending on the area that is being x-rayed (of course, a small one-tooth x-ray is less than a panorama mouth x-ray, and that again is less than a full chest x-ray, etc.). so, if you'd leave the x-ray tube on and stand right in the 'beam', you'd may get radiation sickness in just a few minutes. it is potentially dangerous if you're careless in what you do or dont know exactly what you're doing.
...100ms? It depends on the x-rays power, and that depends on the tube current. Large x-ray machines in hispitals may have the tube current of even 500mA @ 100kV so it can expose the film in such a short time. But it's 50kW! 50kW @ 230V is more than 200A, you would probably need special power line :) I suggest you to look rather for a complete dental x-ray head instead of an x-ray tube only.
Such head includes an x-ray tube with a HV transformer already closed tight in a special casing filled insulatign oil. It needs only 230V to work and you don't have to mess with the oil and high voltage :) It's also preety safe becouse it's well shielded and the tube current is only a few milliamps. The exposure time is longer of course, maybe a few seconds, but the radiation dose is the same as 100ms with a larger x-ray machine.
cool, thanks a lot for all those valuable infos! my guess was 100ms because of what i experienced at my dentist as well as at a hospital, but they have rather new digital x-ray equipment.
that dental x-ray machine sounds like a very good idea though, i'll look into it! again, thanks for the tips!
ps: do you have any videos / images from your x-ray machine?
Looks like you haven't seen my website :) c4r0(dot)skrzynka(dot)org - check the "X-Rays" section - there's a lot of pics. Unfortunately I translated only the "Making X-Ray pictures" to english till now, the rest is in polish only.
thanks - yeah, i still think the final image makes a good piece of radioactive art, too. :-)
i do not have an x-ray tube YET, but i do plan on getting one in the future. i am quite busy lately and i will have to do proper research before running an x-ray tube at home, as this is extremely dangerous if you lack the proper knowledge. but, i will do it one day, that's certain. =)

Wow, you have a very strange hobby.... that seems sooo unsafe doing all these things in your home. You don't have any kids or plan to have any, will you? Do you think about the safety hazards carefully? I wouldn't want to visit your "laboratory".
boamuro 3 years ago 2
nope, i do not have / want any kids and i dont have any pets either. i take care that nobody gets in touch with stuff from my "lab" accidentally. while i may do whatever i want to my own body, i know that it is my responsibility not to put others in dangers with what i do.

I can order an X-ray tube, the only problem is i can't find a source that ships here. If you know any then let me know.
UAEchemist2 3 years ago
the problem with your blurry radiographs is the sources are much too close to the subject and the radiation is too diffuse. take the dead mouse and put it on your setup normally, then take your Sr source (looks like it's the brightest) and suspend it 10-15cm over the mouse/polaroid setup. give it several days to expose (3-4?) before developing. the further away you put the source the more point like it will be and the sharper the shadowgraph will be but also the longer the exposure will need be

thanks a lot of that tip! it sounds pretty plausible, that. the only problem is the amount of time needed for the exposure... i think it would need a week with this weak source. polaroids dont like freezers, but i guess it'd be ok in a tupperware in the fridge. i could just tape the source to the tupperware's lid, too - that should work and not get too messy. i think i'll try this next time i do an autoradiography - again, thanks a lot for the tip!

Aw man :(. Oh well i guess part of being a scientist is learning to live with a number of failures. I'm surprised that the uranium ore didn't yeild any interesting results...i guess i always figured that it put out more gamma than it appeared to have. Oh well.
Hey maybe if you could steal a speck of plutonium from your local government.... :)
ScreamingElectron 3 years ago
lol, i dont think plutonium would work, either. a chunk of plutonium would just expose (whiten) the film completely in no time at all. ^_^
nah, i think the best bet is an x-ray tube, really.

Feel stupid about it - I hoped they would perform better.

dont worry about it - it was a rather certain thing to happen. ;-)
the welding rods only contain 2% thorium OXIDE, and also, a lot of the alpha rays emitted by it will be shielded by the tungsten it is encased into. yet, it's a great item for my collection, because i'd like a sample of every industrial / household appliance that contains radioactive material, so thanks for the tip anyway!
bionerd23 3 years ago
Thanks for testing welding rods. Almost no radiation as I can see from the photo - even the old watch was better. Too bad.
LechuCzechu 3 years ago
I'm thinking maybe the pitchblend on top of the baby rodent was too large, and because the radiation source was just too diffuse, that it washed out the fine details like bones? The smaller the light source, the sharper of an image you can get, so maybe using the Barium or a pure gamma emitter and exposing for 24/48 hrs might make bones visible. The coal radiation might've been washed out from the rad of the other big pitchblende. Great video as always! =)

thanks for your thoughts on this - yeah, well, the exposure on the mouse's hand / feet was surely too long, as you can see - its but a blot. but, if i place the source discs on top of a grown mouse's body (and let them expose for 24 hrs as well), maybe it'd work... i may try this, but i seriously have my doubts, as mentioned in the video.

Doesn't all this exposure to radioactive material induce tumors to the body?
KrypticGuy666 3 years ago
in theory, any amount of ionising radiation MAY induce mutation and cancer. the more radiation, the more of a chance for cancer.
the amount i am handling is far too low to be clearly identified as a cause of cancer, though; you'd have to use much, much higher doses for a high probability of developing cancer due to the exposure to ionising radiation (as there are a lot of other factors that can cause cancer, too).
bionerd23 3 years ago
Just be sure to not have any accidents, and get exposed to an excess of radiation.
KrypticGuy666 3 years ago
yeah, i'll try to keep my received dose as low as possible. :-)

OMG I thaught you will X-Ray the whole mice but when I saw you cutting the mice I started a laughter.
KosmynC64 3 years ago
i thought it may be too thick to x-ray the whole thing... then again - considering the results - maybe not. i may retry it with a whole mouse, just for fun. =)

was ist eig. mit der Uhr, warum ist da Radium drin?
Blinkwing 3 years ago
radium wurde frueher (um 1950) als leuchtstoff verwendet... denn als das radium noch 'frisch' war, hat es wunderbar gruen geleuchtet. die leute wussten damals noch nicht, was fuer einer gefahr sie sich aussetzen... und viele arbeiterinnen, die die uhren bemalt haben - die sogenannten 'radium girls' - sind durch den umgang mit radium gestorben.
bionerd23 3 years ago
wow, hoffentlich wirste kein "Radium Boy" xD
aber ziemlich interessant mit dem Radiumals Leuchtstoff, ist denn bei der Uhr oder speziell beim Radium die Halbzeit abgelaufen?
Blinkwing 3 years ago
nee, ich fress das zeug ja nicht... und wenn, dann waere ich ja auch ein 'radium girl' und kein 'radium boy'. ;-)
die halbwertszeit ist noch nicht abgelaufen; radium hat eine HWZ von 1590 jahren. das zeug dunkelt nur irgendwie innerhalb von jahren (zumindest an der luft, d.h. wenn nicht im vakuum oder unter argon) nach, so dass es seine leuchtkraft verliert... wenn man die uhr mit UV-licht anstrahlt, dann leuchtet sie aber immernoch knallgruen. =)
bionerd23 3 years ago
achso, cool, also kann man sagen, dass das ziemlich oxidiert xD
naja, sry, ich dachte du wärst n boy xD
Blinkwing 3 years ago
yup... ich denke, daran liegt das. weiss ich nicht zu 100%, aber ich denke es mir mal so... passiert ja auch mit anderen dingen, z.b. blei wird ja auch massiv vom sauerstoff attackiert... nach einiger zeit wird das extrem silbrig glaenzende metall daher so grau und stumpf, wie man es ueblicherweise kennt.

hmmm... soviel ich weiss ist patina (die sich auf kupfer bildet, das gruenliche zeug da) kein oder zumindest kein reines oxidationsprodukt... waehrend die graue schicht auf blei definitiv eine oxidschicht ist.

good to know that you´re still alive ;-)
btw i´m makng research about getting strontium out of strontium chloride -> stable strontium metal. Im´going to put it in an ampule just like i did with lithium
btw: oh wow the thorianite is actually really tiny... i thought it was about 4 times as big...
btw RIP mice (yes otherwise they would have been eaten by snakes, i know)
LOL @ for a proper X-ray you will have to use X-rays
sciencoking 3 years ago
yeah, i'm still alive - i'm just quite busy lately and only have time to experiment on weekends, which is rather sad. :-(
interesting idea about the strontium, i'm curie-ous about the results of your experiment, as usual!
and... i will one day buy and run an x-ray tube, but it'll be a while until i can do that... need time and knowledge for it, as it'd be really dangerous otherwise.
bionerd23 3 years ago
lol @ curie-ous
that´s funny... i already did some research about X-ray tubes... they are actually quite safe if you just switch them on for a few seconds (maybe shield the rays that don´t go the right way with lead and it SHOULD be ok)
sciencoking 3 years ago
well, an x-ray is taken in... what, 100ms? and you usually receive doses up to 200 uSv, depending on the area that is being x-rayed (of course, a small one-tooth x-ray is less than a panorama mouth x-ray, and that again is less than a full chest x-ray, etc.). so, if you'd leave the x-ray tube on and stand right in the 'beam', you'd may get radiation sickness in just a few minutes. it is potentially dangerous if you're careless in what you do or dont know exactly what you're doing.
bionerd23 3 years ago
...100ms? It depends on the x-rays power, and that depends on the tube current. Large x-ray machines in hispitals may have the tube current of even 500mA @ 100kV so it can expose the film in such a short time. But it's 50kW! 50kW @ 230V is more than 200A, you would probably need special power line :) I suggest you to look rather for a complete dental x-ray head instead of an x-ray tube only.
c4r00 3 years ago
Such head includes an x-ray tube with a HV transformer already closed tight in a special casing filled insulatign oil. It needs only 230V to work and you don't have to mess with the oil and high voltage :) It's also preety safe becouse it's well shielded and the tube current is only a few milliamps. The exposure time is longer of course, maybe a few seconds, but the radiation dose is the same as 100ms with a larger x-ray machine.
c4r00 3 years ago
My machine (about 10mA @ 70kVp) needs 3-5s to fully expose a photographic paper with "blue" intensifying screen from 1m distance.
c4r00 3 years ago
cool, thanks a lot for all those valuable infos! my guess was 100ms because of what i experienced at my dentist as well as at a hospital, but they have rather new digital x-ray equipment.
that dental x-ray machine sounds like a very good idea though, i'll look into it! again, thanks for the tips!
ps: do you have any videos / images from your x-ray machine?
bionerd23 3 years ago
Looks like you haven't seen my website :) c4r0(dot)skrzynka(dot)org - check the "X-Rays" section - there's a lot of pics. Unfortunately I translated only the "Making X-Ray pictures" to english till now, the rest is in polish only.
c4r00 3 years ago
wow, just took a quick look at it - those pictures are amazing! i will check it out thoroughly this evening, when i have time.
man, that'd be a toy for me indeed...
bionerd23 3 years ago
It doesn't matter if it worked or not, but the final image is amazing! It looks like a photography of distant galaxies or something.
Have you got an x-ray-tube? Experiments with such a device would be interesting!
Keep on experimenting!!!
Kind regards,

LordPlextor 3 years ago
thanks - yeah, i still think the final image makes a good piece of radioactive art, too. :-)
i do not have an x-ray tube YET, but i do plan on getting one in the future. i am quite busy lately and i will have to do proper research before running an x-ray tube at home, as this is extremely dangerous if you lack the proper knowledge. but, i will do it one day, that's certain. =)
