because you were close, did you get radiated from the tube? something like photons or electrons are shot out from the tube as x-rays, and that penetrates your skin and it can give cancer. how much radiation do you need to start the mutation of a human cell?(cancer)
so was the power to the tube shut off when you were measuring it? cause if not, then that means that the tube ionized the enviroment? I dont understand x-rays that well, please forgive my lack of knowledge, its just that im in school to be a rad tech, and that freaks me out because in an x-ray suite when there are not x-rays being emitted, does that mean I am exposed to radiation like this constantly???

@omegalab Not X-rays at these voltages. One you get up to 10 (or was it 100?) MeV you can photofission heavy elements like uranium. Google 'photodisintegration" and 'photofission". Now THAT'S some high energy physics!
@omegalab this is the exact reason nasa never went to the moon.
bremsstrahlung radiation: any beta or proton hitting the ships hull, emits an x-ray, they would have been x-ray ovened to death.
its the same reason why the 'film' returned by the apollo mission was 'accidentally' destroyed when trying to view it. ever since then, only live broadcast footage has been taken.
@Driv3th3hiv3 "all moon rock samples are equivalent to terrestrial rocks, minus slight extra deposits of specific minerals....only 6 small rocks have ever been shown to anyone outside of nasa"
"the FBI hunted down the 'fake moon rocks' stolen from a nasa site".
"nasa are the only space agency to provide evidence to prove the moon landings, and specifically instigate mission in order to 'debunk' 'consipracy theories'"
"nasa also refuses to accept the space race existed."
@Driv3th3hiv3 "in all nasa 'proof' videos, consipracies are 'debunked' by 'former nasa scientists' using the evidence 'no, its a lie' " - (argument from ignorance)
"the plans for the moon lander were destroyed"
"no actual hard photos/film from any of the moon landings survived. only broadcast video is transmitted now."
"beyond seeing an object travelling towards the moon, the rest of the world has little proof to say that it is the truth"
@Driv3th3hiv3 especially considering the US international 'bedside manner', it strikes me as stupid to believe nasa or the american government.
beyond getting confused over the constitution ("this is a christian nation...fight the muslims" - Bush), and starting wars to use new weapons (every president so far)... apollo was invented by predominantly stolen russian documents, stolen nazi documents, and russian and german scientists.
both of which are well aware VAB cannot be crossed yet.
@Driv3th3hiv3 infact, if you know your rocks, you can collect both moon and martian rocks from earth, as pieces of debris. 1 in 250? rocks are from the moon, and 1 in 1000? rocks are from mars, at least by compositional analysis.
at current all the rocks that have been made publically available, are rocks that can be found on earth.
some others that were claimed to have been found, can also now be mined on earth (un-weathered)
@Driv3th3hiv3 more people have died in the american space program, than possibly all other space programs combined.
in traditional american nature, should any american die, war must be sought to avenge them (look at the american military operations timeline - who communities were raised to the ground, over a suspected murder of 'a missing seaman'...burnt to death...)
since america cannot burn itself, fake footage was captured in area 51, and broadcast off a satelite from nasa HQ....
@Driv3th3hiv3 give me one piece of evidence why NASA certainly did land on the moon? (other than, 'everything which the US gov, does not condone is a lie and is satan'...just like your lack or right to oust the freemason government that is occupying your country and poisoned your water with arsenic...)
@daenumen there are still ppl that don't belive we went to the moon? wow, there's retro-reflectors on the moon how do you think they got there? magic? the proof they are up there, well lets see we shine lasers at them to measure the distance between the earth and the moon. if your still not convinced then get your own multi-million dollar laser and do the experiment yourself!
do you think it takes a manned moon mission to put a retro reflector on the moon, or rather, a reflector (like you have on your bike pedals/wheels)?
we used to measure the distance of the moon before we put a reflector up there:
"in 1962 when a team from the Massachusetts Institute of Technology succeeded in observing reflected laser pulses using a laser with a millisecond pulse length"
@Gmc42082 "out of 10^17 photons aimed at the reflector, only one will be received back on Earth every few seconds, even under good conditions (they can be identified as originating from the laser because the laser is highly monochromatic). "
dont be an idiot next time...read the liturature before posting something you dont understand.
@Gmc42082 and also if you would like to know an additional fact, the landing sites were specifically chosen, they are composed of a slightly different rock (known before the landings ie when planning the landing sites) which has a significantly higher reflectivity than the surrounding area due to a higher concentration of metallic mineral containing rocks.
also moon rocks can be and have been found on earth for many hundreds of years.
@Gmc42082 look, think whatever you like, you are entitled to the governments opinion.
a point to think about:
the recent war, what was the reason for the war?:
WTC revenge? international terrorism? israel? crusades? democracy? puppet rulers (non-native saddam and osama with political american ties relating to their initial enstatement of rule)? WMD? reclaimed the chemical weapons sold to iraq in the 1980's? extra military bases? oil? invading iran? zionism? or other?
@daenumen Are you completly fucking retarded? Stop fucking huffing bags of gasoline and maybe your fucking face could produxe a rational sentance you ignorant dope!
@daenumen I have no issues with women. I'm just not attracted to them. Besides... I LOVE to cook. I'd hate to be deprived of that pleasure simply because it's a woman's job. I have a friend whose mother is a horrible cook, and gets very angry if anyone tries to show her new recipes; her food is almost inedible. My friend loves to cook and is good at it, but even though he, too, likes his son's cooking and hates hers, he won't let my friend cook for them because "it's the wife's job".
@JonasClark not 'attracted' to women?! sorry i dont understand what you mean by that remark. please explain.
be deprived of cooking because its a womans job?! who ever said cooking was a womans job?! so what if you know one woman who cant cook?! so what if your friend, if he can cook better than someone elses wife?!
This isnt a competition between the male and female genders, this is about the 'companionship' via 'natural roles' of 'father and mother'...
@daenumen I nonetheless find your "womens' rights oppress mens' rights not to have to clean/cook" comment amusing. Your ">6% of children abused by homosexuals" comment is sad. Statistically, most child abusers are straight...
@JonasClark well the comment about rights was a joke.
the comment is sad, that these people who suffer doubly; having been abused as a child, and in a way that is often contrary to their biological anatomy.
yes 2/3 of the child abusers are straight...and ~90% of the population is straight...
this is not a good idea :). The radiation can be 1000x higher, than you (and you GM) think. You should calculate the possible radiation using for example radprocalculator. select the empirical data option.
You could ask one of the sellers to peel off the calibration standard, it's underneath a metal foil self adhesive sticker (usually black writing on a gold field) that says "OPERATIONAL CHECK SOURCE" that should eliminate the problem as long as you do not mind losing the check source. If the source was lead or bismuth it's probably half deplete by now anyway, the Depleted URANIUM would still be good though.
So did your meter peak out at about 300 mR/hr? that's what it kinda looked like. I have the cdv-700-model6b and the cdv-717, both in excellent condition, the cdv700 has been moded with some more modern parts, and a switch for fast/slow meter readings. I have another cdv-700 that is getting overhauled real soon, and getting a scintillation probe reftrofitted to it.
I'm just a student radiographer, but In the grand scheme of things not alot. 30KVP is pretty low voltage peak (In a clincal setting a toe would need about 50-60Kvp).
Kvp is the energy the photons have (How much peak penetrability they have, while mA determines how many photons total are produced). I assume with such a long exposure time, the mA is very low to help prevent the anode from melting so he can video this. sandman762 is extremely wrong, drop off is controlled by inverse square law.
this person is irradiating his neighbor and anyone downstream. Looks like you did an excellent job of dissassembling an old portable Xray machine to obtain the ray tube. Please stop irradiating your neighbors.
X-rays are light and thus are subject to the inverse square law this means the power drops off very quickly with distance. So unless he is in an apartment complex he's probably not endangering anyone else.
it's funny how the components of an x-ray tube by themselves aren't radioactive but with the introduction of electricity they can be a serious health hazard.
Makes me wonder about OTHER 'electronic' devices people carry every day...
how many kilovolts you running? I got a "EG252C" tube. It is about 7" diameter and 24" long. similar to yours, looks like. Water cooled anode. Looking for the filament and HV specs..
I didn't finish my xray photography project yet, but i have 2 radiological imaging unit ( one is :TH 59428) with monitors. I think, i can repair them, and then i can make x-ray videos, or pics, with very low dose rate.
Wow, I'd literally pee myself if I had a set-up as strong as that... that's like, freakin Electric Radium... might be worth trying to take some salt and discolor it from clear/white to brown, something that strong might be able to pull it off!
I have the exact same CD Geiger counter as in the video. I also have a radium test source. This setup is significantly stronger than the readings for radium.
A radium test-source sure, but how about 50 grams of radium or more? My own very feeble X-ray source vastly surpasses my 10 uCi Cs-137 test source... making X-rays, especially with a rig like this, is the only way amatuers can get access to the levels of radiation the Curies et al. had at their disposal back when they had grams of radium to play with, hence my analogy. It would be curious to know how much radium it'd take to match the radiation levels his rig is putting out... surely lots!
indeed. Something to keep in mind.. the detector is internal. meaning the radiation has to go threw the metal. So imagine the real levels! I wouldn't want to be anywhere near that thing when it's running.
At MRI is a magnetic resonance imager. If he went near the machine with the meter....well It would fly across the room and attach itself to the machine permantly.....dont you mean a CAT scanner...
awesome job! you ever see nikola teslas xray research! i think the books called xray vision by nikola tesla. he sent powerful xrays over 60-100 ft from the xray tubes he made and he also shown the first safety mechanisms to keep people safe, he even sent the xrays down only one wire without a electron decelleration target, i think modern science calls it bessingerung! teslas materials and tubes are the same they made ever since! tesla even helped rotengen perfect his devices!the book is amazing!
by the way thank you for doing this! it helps people understand what would go on in an experiment, i was wondering if you were wearing some type of lead apron, kind of scary, the most powerful radiation i have produced is ultraviolet, it makes a ton of ozone almost instantly! its actually really sickening when you have to much of it lol. its still amazing to me how easy xrays are able to be made! 5 stars, takes alot of balls to do that !lol amazing!
Have done that before. Like what omegalab said, Don't monkey around with that.
However, I have done with radio tube before, and X-ray laser too. (The X-ray laser emission is like 7 - 145 times brighter than dentist X-ray tube - if placed right in the laser beam's path, the digital Geiger Counter could end up displaying "OL" or "Overload")
i am not stupid and i dont want to irradiate myself all the day. Im just very interested in radiation and i have a lot of lead to shield it. btw isnt a small x ray tube lessdangerous due to less radiation?
there are so many factors really, shielding, the voltage gradient, the deceleration target,even no target, if you do this be very careful, i wouldnt, to many invisible factors for me right now until i have a better lab lol.just do the simple "pull scotch tape really fast in a dark room" and you can get basic xrays that will be gone once you stop pulling the tape in like a fraction of a second!
but it would be funny (with a really small amount of them, just enough to make those screens glow and not more than a minute one day every week which will be the average using time if i had it because it becomes boring soon :P)
hahaha lol, funny! well i saw your other comment about pressing you to the wall or disolving from the powerful xrays, that was very funny! yea i guess the tape thing has its limits too lol. xrays are really intresting though arnt they? its amazing like all of these different em waves and how they resonate with different chemical structures, like mirowaves excite water and some proteins, ultraviolet makes free ions on tyamine in the dna, and xrays like totally break up the dna strands.crazy stuff
then you got like heat/infared and radiowaves excite a larger group of electrons in a wire things like that, all about resonating target structures, something like that lol
yep, gamma rays can even destroy crystal grids, and the solar quantums that are absorbed by the air in 400 km height can even kick hardons out of nuclei. imagine: they´re gamma rays with 50 MeV o.O gamma rays usually don´t become stronger than 1 MeV
But I would hold much more distance to the tube despite of the laws of quadratic decreasing of radiation. Those rays are highly energetic and can cause easily cell damage.
Maybe I'm going to try that too with pothographic discs.But in a shelter in our garden, with enough lead and distance to the source. Then I will use a ordinary vacuum diode tube like the GY501 as x-ray source.
Flooding a room with XRAYs is simply dangerous to put it mildly. Looks like you have between 5-10 R/hr coming off the tube which is around standard for a tube of this size. Not something I'd do - ever! C A N C E R R I S K
I'd never say that your an idiot! Its pretty cool to see someone have the guts to play with an XRAY tube! I just wouldn't want to see you get a life changing diagnosis of cancer because you irradiated yourself! Play safe, dude!
You are right, this was the one, and last test with opened tube. I try to scan the whole house for diffused xrays, but the walls are good as shields. And after this I went to the cellar with GM counter.
The tube rated 60kV. The xray producing vs voltage is not linear, so if I put 60kV to the tube, the possible radiation will be 50-100R/h. But I dont want to do this. I wonder, what it makes, when I hang it to 100kV.
I don't know man radiation period is pretty bad S*** but if you feel safe with millions more particles streaming through your body @ thousands of miles per hour go ahead!
so your saying...X-.1 is the lowest sensitive setting? or is X-100 the lowest?
Well, since I happen to have a nifty chart from Boston Edison of what different levels of radiation do to the human body, I can tell you what would actually would happen.
100-200 Rem: Decrease in White Blood Cells; recovery in several weeks
200-300 Rem: Fatigue, Hemorrhage, Infection, Erythema, Sterilization; recovery in 1-12 months, 0-40% incidence of death
300-500 Rem: Fatigue, Hemorrhage, Infection, Erythema, Sterilization, Hair Loss; long recovery, 40-100% incidence of death
for anything to show up on a 715 is amazing, given they were only supposed to be used for massive amounts of radiation

I'm just a student radiographer, but In the grand scheme of things not alot. 30KVP is pretty low voltage peak (In a clincal setting a toe would need about 50-60Kvp).
Kvp is the energy the photons have (How much peak penetrability they have, while mA determines how many photons total are produced). I assume with such a long exposure time, the mA is very low to help prevent the anode from melting so he can video this. sandman762 is extremely wrong, drop off is controlled by inverse square law.

Everytime this X-Ray tube is turned "on"
this person is irradiating his neighbor and anyone downstream. Looks like you did an excellent job of dissassembling an old portable Xray machine to obtain the ray tube. Please stop irradiating your neighbors.
sandman762 2 years ago
This person has measured all of the diffuse rays outside, and inside, so please dont know this better than the person.
Thank you.

X-rays are light and thus are subject to the inverse square law this means the power drops off very quickly with distance. So unless he is in an apartment complex he's probably not endangering anyone else.

it's funny how the components of an x-ray tube by themselves aren't radioactive but with the introduction of electricity they can be a serious health hazard.
Makes me wonder about OTHER 'electronic' devices people carry every day...

I have the exact same CD Geiger counter as in the video. I also have a radium test source. This setup is significantly stronger than the readings for radium.
trustthewater 2 years ago
A radium test-source sure, but how about 50 grams of radium or more? My own very feeble X-ray source vastly surpasses my 10 uCi Cs-137 test source... making X-rays, especially with a rig like this, is the only way amatuers can get access to the levels of radiation the Curies et al. had at their disposal back when they had grams of radium to play with, hence my analogy. It would be curious to know how much radium it'd take to match the radiation levels his rig is putting out... surely lots!
AScannerClearly 2 years ago
indeed. Something to keep in mind.. the detector is internal. meaning the radiation has to go threw the metal. So imagine the real levels! I wouldn't want to be anywhere near that thing when it's running.
trustthewater 2 years ago
so if you got exposed to that radiation you'd be fucked, right?

awesome job! you ever see nikola teslas xray research! i think the books called xray vision by nikola tesla. he sent powerful xrays over 60-100 ft from the xray tubes he made and he also shown the first safety mechanisms to keep people safe, he even sent the xrays down only one wire without a electron decelleration target, i think modern science calls it bessingerung! teslas materials and tubes are the same they made ever since! tesla even helped rotengen perfect his devices!the book is amazing!
boxa888 3 years ago
by the way thank you for doing this! it helps people understand what would go on in an experiment, i was wondering if you were wearing some type of lead apron, kind of scary, the most powerful radiation i have produced is ultraviolet, it makes a ton of ozone almost instantly! its actually really sickening when you have to much of it lol. its still amazing to me how easy xrays are able to be made! 5 stars, takes alot of balls to do that !lol amazing!
boxa888 3 years ago
Have done that before. Like what omegalab said, Don't monkey around with that.
However, I have done with radio tube before, and X-ray laser too. (The X-ray laser emission is like 7 - 145 times brighter than dentist X-ray tube - if placed right in the laser beam's path, the digital Geiger Counter could end up displaying "OL" or "Overload")

"This is extremely dangerous, don't try this nowhere else!!"
The warning is true, please observe this.
omegalab 3 years ago
i am not stupid and i dont want to irradiate myself all the day. Im just very interested in radiation and i have a lot of lead to shield it. btw isnt a small x ray tube lessdangerous due to less radiation?
sciencoking 3 years ago
there are so many factors really, shielding, the voltage gradient, the deceleration target,even no target, if you do this be very careful, i wouldnt, to many invisible factors for me right now until i have a better lab lol.just do the simple "pull scotch tape really fast in a dark room" and you can get basic xrays that will be gone once you stop pulling the tape in like a fraction of a second!
boxa888 3 years ago
but it would be funny (with a really small amount of them, just enough to make those screens glow and not more than a minute one day every week which will be the average using time if i had it because it becomes boring soon :P)
sciencoking 3 years ago
hahaha lol, funny! well i saw your other comment about pressing you to the wall or disolving from the powerful xrays, that was very funny! yea i guess the tape thing has its limits too lol. xrays are really intresting though arnt they? its amazing like all of these different em waves and how they resonate with different chemical structures, like mirowaves excite water and some proteins, ultraviolet makes free ions on tyamine in the dna, and xrays like totally break up the dna strands.crazy stuff
boxa888 3 years ago
then you got like heat/infared and radiowaves excite a larger group of electrons in a wire things like that, all about resonating target structures, something like that lol
boxa888 3 years ago
yep, gamma rays can even destroy crystal grids, and the solar quantums that are absorbed by the air in 400 km height can even kick hardons out of nuclei. imagine: they´re gamma rays with 50 MeV o.O gamma rays usually don´t become stronger than 1 MeV
sciencoking 3 years ago
I have always wondered what would happen if I took a Geiger Counter into the room when I have a CT Scan.
LukeL007 3 years ago
Wow really impressive experiments...
But I would hold much more distance to the tube despite of the laws of quadratic decreasing of radiation. Those rays are highly energetic and can cause easily cell damage.
Maybe I'm going to try that too with pothographic discs.But in a shelter in our garden, with enough lead and distance to the source. Then I will use a ordinary vacuum diode tube like the GY501 as x-ray source.
Greetings from Germany
kla989 3 years ago
Yes, I need a big amount of lead too, I want to make some xray pics.
omegalab 3 years ago
Flooding a room with XRAYs is simply dangerous to put it mildly. Looks like you have between 5-10 R/hr coming off the tube which is around standard for a tube of this size. Not something I'd do - ever! C A N C E R R I S K
icuicu2006 3 years ago
The radiation was about 0,5R/h. Next time I use the 'closed' tube, because I am not an idiot.
omegalab 3 years ago
I'd never say that your an idiot! Its pretty cool to see someone have the guts to play with an XRAY tube! I just wouldn't want to see you get a life changing diagnosis of cancer because you irradiated yourself! Play safe, dude!
icuicu2006 3 years ago
You are right, this was the one, and last test with opened tube. I try to scan the whole house for diffused xrays, but the walls are good as shields. And after this I went to the cellar with GM counter.
omegalab 3 years ago
1) that scared the shit out of me....
2) why did you have the counter on its most sensitive setting?
3) damnet! you beat me to the punch!
conrad2468 3 years ago
The gm counter has one sensitive setting. The tube worked at the lowest voltage, that produces xrays.
omegalab 3 years ago
ohhhhh
conrad2468 3 years ago
The tube rated 60kV. The xray producing vs voltage is not linear, so if I put 60kV to the tube, the possible radiation will be 50-100R/h. But I dont want to do this. I wonder, what it makes, when I hang it to 100kV.
omegalab 3 years ago
I don't know man radiation period is pretty bad S*** but if you feel safe with millions more particles streaming through your body @ thousands of miles per hour go ahead!
so your saying...X-.1 is the lowest sensitive setting? or is X-100 the lowest?
conrad2468 3 years ago
x.1 is the lowest (0-500mR/h)
omegalab 3 years ago
and x.100 is what ect?
conrad2468 3 years ago
x100 is 0-500R/h.
omegalab 3 years ago
well, imagine you really get 500 R/h it will probably dissolve you immediately or press you to the wall lol
sciencoking 3 years ago
Well, since I happen to have a nifty chart from Boston Edison of what different levels of radiation do to the human body, I can tell you what would actually would happen.
100-200 Rem: Decrease in White Blood Cells; recovery in several weeks
200-300 Rem: Fatigue, Hemorrhage, Infection, Erythema, Sterilization; recovery in 1-12 months, 0-40% incidence of death
300-500 Rem: Fatigue, Hemorrhage, Infection, Erythema, Sterilization, Hair Loss; long recovery, 40-100% incidence of death
