new radioactive lot + an introduction to further experiments

[stefaan10111992]

what defines if the source emits alpha-, beta- or gammaradiation?

[grantodamax]

ok 2 questions 1 i dont mean to say oh you a child but how old are you? and 2 what do you do with the radioactive materiel?

[WolfPackAttack1911]

Radioactive things scare the hell out of me

[TheNigahiga2]

aren't you scared you're going to get cancer or something?

[antiprotons]

I just bought the same Sr 90 0.1 uCi sample as you! Super fun science!

[pooppeeyoupants]

PUT IT IN A LEAD CASE QUICK BEFORE IT KILLS US ALL!!!

[edpotkay1]

ya the little plastic container contains it. hope she doesn't want kids

[usernamen0tfound]

lawl, i love how you just pick it up xD even thoe its radiation xD

[suzuki4life7]

geta fucking life who wants to collect radio active shit u really want to die dont u

[phixxwutwut]

@suzuki4life7 isnt her life studying radiation? what do you do for a living?

[kvrisu]

You can buy all of this at unitednuclear (dot) com. I mean, seriously. I'm not a bot :P

[KarbineKyle]

NICE COLLECTION! If I die, I want to give you my radioactive collection! You're so educated at what you do! You truly are inspiring! These radioactive sources are exempt quantities, and they're great for experiments! SO MANY people believe these radioactive sources are this dangerous? My mother was diagnosed with Grave's disease the other day =(. They gave her 200uCi of I-123. That's still not that much. I asked her do to what you did in your Tc-99m scintagraphy! She did! It was gross, but cool!

[bugkiller121]

you shit ! that dosent looks like radioactive material asshole

[Doppelbuckel]

@bugkiller121

I guess you can see ionizing rays? Dumbass.

[AZNTHEORY]

shoudint you be dead because of all of the rad material you have?

[Huffdev]

where did you get those?

[gta4everybody1]

you can fuckin dye right ?

[mahin300]

what will happen is u drop the ceasium in water

[realranzen]

Hallo – haben sie das Material von »Untied Nuclear«? Ich bin auf der suche nach welchem zu Forschungszwecken, aber leider kann ich keinen supplier finden, der ausserhalb der US liefert. Danke & Gruß

[yourTIV0]

Omg, you got caesium. I thought it was impossible to get that stuff.

[AgentCROCODILE]

2:10-2:19 = "and inside you will put alcohol which will evaporate and after air on the top side is much warmer it can take much more alcohol it can absorb much more alcohol and thus it will get heavier and then sink back down and"

[AgentCROCODILE]

I reckon I'd be more worried about one's health if they got one of those old "Tazos" and stuck a radation sticker on it and made videos about it, than holding one of those tiny arse radioactive sources.

We're exposed to ionizing radiation all the time you see. :)

[alisamarie55]

I can't believe you're handling all of these radioactive materials without any protection.

[whoopla1095]

Where can i get these materials? i live in USA

[mgregggphone]

@whoopla1095 Although the prices aren't great united nuclear sells samples like the ones shown.

[pzmtuthcvpvl]

Universe's age is 13.73±0.12 billion years

U238 Radioactive Decay half-life: 4.46 billion years

So where did the Uranium come from? Stellar core production of helium from proton-proton reaction does not account for acceleration well beyond escape velocity, let alone how a heavy-metal gets from the core to the surface. Calcium seems to be the heaviest element that is elicited ....

[bionerd23]

@pzmtuthcvpvl

first of all, one half life means that 50% are left. after two half lives, there's 25% left. three half lives, 12.5% left... and so forth. so, the amount of uranium we have is probably just a tiny fraction of what was there "in the beginning", but seems a lot, as we have nothing to compare it to.. ;)

...plus, uranium and other heavy elements (above mass number 55) are constantly re-created in supernovas. so, the next supernova might spit some fresh uranium into the universe!

[pzmtuthcvpvl]

@bionerd23 "might" means we have no scale with which to grasp planetary abundance of { or paucity of } elementals + no reasonable proof that planetoid generation occurs primarily from super-nova remenant(s) ... who''s to say that all planets circle stellar centroids? Maybe planets wander aimlessly in the void - sweeping up various super-nova results, maybe California's Pink Salt Lakes harbor strange nucleotides - the abundance of hydrogen / helium in stellar is inconsistent with terrestial ...

[caluber55]

@bionerd23 do these samples cost money??? im from england can i get some ???

[yofail1]

@bionerd23 whwere do you get the radioactive stuff i checked united nuclear and all of there stuff is sold out plz halp 

[steamingpoopfart]

the earth is 6000 years old

[Candunc]

@steamingpoopfart

Really, you are very smart.

[LevelUpification]

@steamingpoopfart

?! the earth is 6000 years old. where did u learn that????

[TroutButter]

@LevelUpification From EXTREMELY delusional people with their heads in the clouds of fairy tale land. :)

[hacky33]

hey men your videos are cool

but doesent you get a litle radio active wth al that stuff becouse a littel plastic class cnat hould the nuclear rays?

[sparkey989]

@hacky33 Are you seriops. Letm me talk lime tdis f1rst.

n() compney would sel stuf if a caes coudent huld it of cerse shees fien

[brokenjdogg69]

a better question is where the fuck do you get radioactive stuff. if you fuck up you could kill people.

[bionerd23]

@brokenjdogg69

nah, they're exempt quantities (amounts of radioactive material which one can own legally without requiring licensing or professional training) for a reason. ;)

as you're from the USA, i can even tell you something about it (i only know the laws for germany and have a small insight into US laws, as i obtain my material from the USA)... so look here:

NRC Regulations

Title 10, Code of Federal Regulations

§ 30.18 Exempt quantities.

§ 30.71 Schedule B.

[pzmtuthcvpvl]

@bionerd23 nrc dot gov slash reading-rm slash doc-collections slash cfr slash part040 slash part040-0013 dot html

[bionerd23]

@pzmtuthcvpvl

what did you send me that for? i dont live in the USA. but yeah, those sources are as of exempt quantities in the USA, too, as that's where i bought them. ;)

[pzmtuthcvpvl]

@bionerd23 I sent that on the basis that many international viewers of all nations across political boundaries could use the information for some effective purpose ~ speaking of which are there any common plastics that could serve as crude scintillators for background levels of Sr-90|I-131|Cs-134|Cs-137|Ru-1­03|Ru-106|Pu-238|Pu-239|Am-241 ( ? )

[steamingpoopfart]

it can still harm you and is and needs to be kept in a lead case

[Tilmeez100]

Where i get these element in Pakistan?

[Tilmeez100]

Hi!

Where i can buy these element in Pakistan.

[WVCivilDefenseFreak]

where did u get ur radiation meter from ?

[bionerd23]

@WVCivilDefenseFreak

the store is called conrad.

[tomato098]

I DARE you to put that caesium in a bath full of water.. dont forget to post results ;D

[sparkey989]

@tomato098 Or get some plutonium and

[SPOILER]

drop it XD

[Powdermonkey09]

How do you know we don't want details? Since people keep asking; Your gamma scout is a GS2 But like you said they're sold as gamma scout GS1 and Gs2 Gamma scout w/ alert. No differences just an audible alarm.

[mucofresh]

thanks

[mucofresh]

isnt it dangerous that you are touching this radiation with out protection?

[bionerd23]

no, because it's a really minor amount. otherwise, these disks wouldnt be "exempt quantities", either. :)

[TheMaliPerica]

Is your gamma scout GS1 or GS2? I'm planing to buy one but there are these two different types.

[bionerd23]

we dont have these terms in germany; i only ever saw "gamma scout", "gamma scout with alert" and "gamma scout online version" here; i have the w/alert one.

[TheMaliPerica]

Do you have a Facebook profile?

[bionerd23]

nope, i dont use social networking.

however, somebody created a fan account or something on facebook - dont mistake that person for me, though.

[kettu92]

The settings on your geiger when it show like 2,00 uSv/h. Do you compare it to 0,002 Sv? And does 1 hour of that dose add the 2 uSv to your early radiation doses?

[bionerd23]

0,002 Sv would be 2 mSv. 2 uSv = 0,000002 Sv. and yes, one hour at that dose shown on the dosimeter does indeed add this to my yearly exposure, that'd be correct.

[bionerd23]

*if it is a full body dose, that is.

[kettu92]

thanks for replying, im only teaching myself what i read on the internet. So i must ask someone who know to get it right. But i think you wrote wrong about mSv. The bakground radiation is about 4mSv, and if you get 1 Sv you will get a light radiation poisoning

[bionerd23]

the background radiation is a mere 0.15 uSv/h here, but up to ~0.30 uSv/h can be normal. yes, MICROSIEVERT. i'm 100% sure of that.

[wolfang12alpha]

Where did you get these radioactive elements? I'd like to get my hands on one of them.

[jackycck2222]

Be careful for cancer...

These radiations are deadly !

[919664]

how old are you ? are you a girl or a boy?

[bionerd23]

26 and thus, i'd consider myself a woman, not a girl.

[919664]

ya ich weis aber ich hab nicht gewisst wie alt bist du. und deine stimme klingt ein bischen kindisch :D.

[bionerd23]

ich weiss, ich hatte schon immer die stimme von einem kleinen jungen... ;)

[919664]

@bionerd23 genau dass habe ich gedacht dem ersten mal dich gehört hab :D. wann hast du diesen Radioaktivität kram gestartet ? srry aber mein deutsch ist nicht so gut. Ich hab deutch gelernt vom TV (wie Spongebob Schwammkopf (super RTL) und Galileo (pro 7)) Tschüss

[bionerd23]

vor ca. 3.5 jahren, glaube ich...

[KarbineKyle]

I do, I have a small booklet that I "made", and I have my own decay chains that I wrote out myself. I know that T1/2 is not like "100uCi of Iron-55" will disappear in 2.73 years by half, but it will decay by counts of half. Like if I do a simple proportion, I will know how many uCi of Fe-55 I will still have left. For example, in 8.19 years, I will have 25uCi of Fe-55 left. It decays by e- capture to Mn-55. The C-14 is what I want for my 26th B-day, but I can't afford disc sources, I'm broke...

[bionerd23]

yep, that's correct, but i was more asking why you'd want such a weak beta emitter? it emits just 50 keV of beta radiation.

[KarbineKyle]

Awesome! I love your experiments with different types of sources! It's amazing what you can do! A little goes a long way! I guess that's true. I'm hoping to buy a needle source or some disc sources, but I am broke right now... I would really like to get a disc sample of 100 uCi of Iron-55 (Fe-55), but it has a short half-life of only ~2.7 years... I would rather get a disc of the 10uCi of Carbon-14 (C-14) first though, since it has a half-life of 5730 years! Keep up the incredible work! 5/5!

[bionerd23]

you should look into the decay mode / emitted radiation more than into the activity / T1/2, it's much more important for experiments. what would you want to do with C-14? :)

[olguiuxx]

wait a police take you man

[bionerd23]

why would they do that? it's legal to have those, as they're exempt quantities. :)

[martyn347]

where did you get :barium 133,strontium 90 and caesium 137.they look like you buyed them in store...is it possible to buy that in store?

[huntpivot2]

those are actually what the labels say for about 4 hours, thanks to everyone's favorite thing, half-life.

[bionerd23]

lol, well, nothing you can do about that... ;)

[ScandalB52]

Question,Is Neptunium avaliable for sale? or maybe Acitinium? and is Led Radioactive?

[bionerd23]

likely, you just gotta find out where... and if there is an exempt quantity of it. ;)

lead has both radioisotopes and non-radioactive isotopes. the one in this video is a radioisotope, of course... Pb-210.

[zasx20]

now, i know for a fact that can't be good for you. arent you worried about cancer,cateracts,moles,etc.? ps were did you get that detector i have only one radio sample and that is Am 241. pls any one may reply

[bionerd23]

no, i am not worried about that, as the dose of radiation from the sources i have are WAY TOO LOW to produce any of those effects. of course, there's an increased risk for cancer, in theory - but it's minor, same as when taking x-ray images e.g. at the dentist. it's only a stochastic risk.

i got the detector (gamma scout) from a local electronics store called CONRAD.

[vitorix24]

where you get radioactive meterials?? :D

[TheAlecweber]

they were selling delplete uranim on amazon no joke

[vitorix24]

LOOOOOOOOOOOOOOL

[nepssis]

How to order radioactive material? I'm working with some radium school source at my faculty, but I can't take it home for testing purposes. Can you help me getting one?

[krisish00d]

aren't you worried about getting cancer?????

[anfokg]

where did you get???

[BrunoEA12]

please tell me how you get these radioactive elements!?!?

[combine988]

Are you going to make a video of the cloud chamber in use? That would be very cool.

[bionerd23]

yes, i am planning to do so. as i need dry ice for this, i am planning to do it once it's colder (so likely in autumn)... plus, i am working on another project right now. :-)

[combine988]

Ah, I understand, looking forward to it :-)

Oh, and what is your other project?

Secret? Breeder Reactor?? Nuclear bomb???

You tell me :-)

[bionerd23]

lol sorry, nope, nothing as cool as that. :P

you will find out what it is once i uploaded the video about it. be patient. ;-)

[killeninicent]

where do you get these radioactive elements!?!? =)

[micLuc14]

do you know what it looks like inside those yellow capsules?

[bionerd23]

not more than what i can see through the source window.

[lashleyflaypool]

you are the coolest fucking chick in the world. i love this. i am also obsessed with chemistry. mainly nuclear chemistry. fucking sweet! all of your videos are pretty cool. i love how you do these radioactive experiments in your bedroom. fucking cool dude, i cant say it enough.

[bionerd23]

i dont really have a choice, as my flat only has of one room... i wish i had a proper cellar. oh well, maybe, one day...

but anyway, thanks! glad you enjoy my videos. =)

[gkyy3c]

you must have 13124 types of canceer

[bionerd23]

that'd be awesome, i could make a fortune as a test subject then!

[whoopla1095]

@gkyy3c Any ways haha,  he held a geiger right up against UNCUT uranium.

[fukinstevo13]

do you glow?

[jodex96]

Haha!! Those aren't very dangerous..(maybe:)

[AuthorityComplex]

my computer is not powered by a nuclear reactor.

its good old fossil fuels for my energy needs

[JonnyB16902]

Where do you get this stuff?

[legominifigure7]

how big are the source disks?

[bionerd23]

uh, 1" i think.

[legominifigure7]

ty. they looked small... :D

[bionerd23]

its not like that matters for such a short-lived radionuclide, anyway. even a 1/8" disc of PURE Cs-137 for example would put you into really, really big trouble.

why have a large plastic disc around an amount of atoms that is not even visible to the human eye?

[Dharok60]

but where can i get radioactive source disks?]

i dont live in the us so i cant buy stuff from united nuclear. is there a place that i can buy source disks online that ship to canada and accepts orders from canada?"

[Dharok60]

but i live in canada so i can buy stuff from united nuclear

[Dharok60]

where did you get the radioactive disk sources and the gamma scout?

[bionerd23]

i got the gamma scout from a german electronics store, but you just need to google it to find it on the web as well. same as with the source disks - they're available e.g. from united nuclear.

[Hades8784]

Say, whats the average battery life of the gammascout? I am a bit worried about its lack of a user-serviceable battery, or perhaps that has changed?

[bionerd23]

if exposed to normal background radiation levels and the audible click is not used for more than 10 minutes a day, the gammascout's battery is supposed to have a lifetime of 10+ years. at the end of life, you will have to send it in to the manufacturer to have the battery and / or the geiger mueller tube replaced though, that is true.

[Hades8784]

Well then, 10 years isn't so bad after all, well worth it for such a good design. I look forward to more videos, I can learn quite a bit from you, it seems!

[Isosphere]

anybody with a soldering iron can change the battery, quite an easy job. I did it.

[bionerd23]

erm, and where did you get the battery?

[Isosphere]

All major electronic suppliers have it, standard

stuff. Nothing special.

[bionerd23]

oh, ok, didnt know that! thanks for the info!

[86Cado]

how the fuck did u get radioactive materails!?

[ethanswish123]

united nuclear

[bmwlacrosse996]

@86Cado Probably United Nuclear

[klutz22]

LOL "Deep shit"

[Nby21Blog]

wow this was awesome :). From where can you buy those strontium , cesium and barium samples? Because i want to get my hands on some radioactive materials, because i want to try something outon how radionuclides affect life and how could you shield them better. I will try to persuade my chemistry teacher to give me some info about where i could get some, to use it for a good cause, ofcorse. Keep up your very entertaining & educational movies, we live them ! :D

[bionerd23]

i really dont know where you can get this stuff in romania, but a lot of US companys - such as united nuclear, google that - sell those source disks. you have to do some tricking and / or mail forwarding services etc. though - and you may get in trouble with customs. i was called by a radiation protection officer whom i had to explain what i needed those source disks for... german customs are very strict, they do scan for radioactive stuff, and they opened my package.

[Nby21Blog]

oh i see, i once wanted to order from united nuclear, but it says it will only ship to the US... but i will go to the bazar sunday and search for old stuff like smoke detectors or cathode ray tubes, mercury switches and other stuff... been asking many people on where to get uranium ore or similar radioactive material, they say in a mine or to talk to scientist (luckily i know one, he explained me what plasma was). i am trying to get my hands on an x-ray tube, it would be just awesome.

[polonium9]

I WANT A GAMMASCOUT SO BAD but it costs a little much for my tastes

[ScreamingElectron]

Me too

[Ballpythondude420]

I WANNA HEAR THE DETAILS

[m3sca1]

im looking forward to your cloud chamber experiments.

are you going to try actually x-ray imaging anything with the film exposures?

maybe a watch or other mechanical device would be interesting.

Nikola Tesla was doing "shadowgraphs" as he called them.this was at the same time Roentgen was messing with x-rays.

Tesla produced stonger emissions though using his resonant air core coils,and made some excellent examples of early x-ray photography.

[bionerd23]

well, i was thinking of x-raying a dead mouse for starters. :-)

i dont know if it works at all due to the low radiation (an x-ray is performed in less than a second, while i will need a couple of days to expose the x-ray film with the same dose) and different energy of the rays, but if it does work, i will x-ray other things such as electronic devices as well. :-)

[iloveallecchianime]

whats to stop a terrorist from buying alot of that radoiactive stuff?

[SeanStrife]

If you buy too much of a certain thing then you might raise a few red flags.

[iloveallecchianime]

Its called using alot of people to buy 1 thing and adding it all together

[SeanStrife]

It's not to say it's a foolproof plan, but it's better than nothing.

[AScannerClearly]

These sources really contain only a relatively small amount of radioactivity, hardly useful for using against people. You'd need hundreds of sources, which would be expensive and draw a lot of attention if they're bought up and sent to the same general area in a short period of time. Alpha emitters are much more strictly regulated; Beta & Gamma are less damaging biologically and less useful for terrorism.

[bionerd23]

as the others already explained, you would need insane amounts. but let's say you had a lot of people all over the world and a lot of time, so it doesnt 'raise the red flags'... AND also a lot of money... you can then go on and, for example, buy Polonium that killed Litvinenko, yes. you would need combined sources worth approx. $800.000 though... but in theory, it is possible. i guess most terrorists would make deals with the russians rather than ordering it from official US companys though...

[bionerd23]

oh yeah, i meant: sources worth $800.000 are roughly enough Polonium - if combined - to kill ONE adult human being.

[Blinkwing]

schöne boxen!!

wollt immer mal was radioaktives sehen!!

[sciencoking]

*FLEEEEEEEENN* mensch... schade dass ich keine kumpels aus amerika habe... wobei... hmmmm ich könnte mal polonium9 fragen ob er mir das zeug besorgen kann :DDDDDD *sabber*

[bionerd23]

du kriegst auch noch was schoenes, wart's nur ab. ;-)

[AScannerClearly]

Wow, you're very much equipped to do some hardcore neat radioactive stuff type things!! How long does it take to get a autoradiograph from your Uranium ore? And how many microcuries are each isotope source? I've got a 10 uCi Cs-137 that's quite a bit hotter than yours seems to be, in fact it's hottest thing I have! I've also got 10 uCi of C-14 but that's a total waste of money; the Betas are about as weak as Alphas. Looking forward to your next videos! :)

[bionerd23]

haha, well... the thing is, i am from germany. germany has really weird and totally different (not nessecary lower) excempt quantities than the US; for Cs137, its 10kBq, which equals to 0.27 uCi - so i got a 0.25 uCi source disk. :-)

i was called by a postal customs officer and then had to speak to a radiation protection officer about this though, he asked me what i am going to do with it. i convinced him of being knowledgable though. :-)

[bionerd23]

anyway, it tooks four days to ship, and over two weeks to get it sorted out with customs. nothing radioactive goes through there without them noticing. so yeah, i'm glad i have them sources after all! if i ever needed more caesium 137, i could always combine multiple sources... how silly.

anyway, i got: 0.25 uCi of Cs137. 0.1 uCi of Sr90. 1 uCi of Ba133, and 0.01 uCi for the lead 210 needle source.

[bionerd23]

the autoradiograph you saw on the example in the video - which exposed the film a lot, ie. made it bright white at some points - was a 20 hours exposure.

oh yeah, another weird german thing is that you may have everything, but in some cases only very tiny amounts (and if you can explain it to an officer in case you dont have a scientific company, hehe)... Am241 as well. afaik i know, in the US, Polonium is the only pure alpha source that is available to buy in excempt quantities? weird.
