new radioactive lot + an introduction to further experiments

yay, new toys - caesium 137, strontium 90, barium 133, lead 210 - for me, the hobby scientist! \o/

in this video, i try to explain a bit about the properties of the above mentioned radionuclides as well as what i am planning to do with them.

by the way, sorry for some rather cough 'cuts', the original video was about twice as long... as youtube doesnt accept videos longer than 10 minutes AND i thought it'd be TMI (too much information), i cut it down to a single 10 minutes video.

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 ....

@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!

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

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. ;)

[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?

[yofail1]

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

[antiprotons]

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

[caluber55]

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