Or, at least, you can be sterilized from mining uranium...

yeah, steralise you by putting you through a gamma radiation machine.... that sounds like fun :D

is there enough density in uranium ores in mines to be globally dangerous? i mean, explosion in canada starts gigantic nuclear reaction?

Not for about two billion years, and explsions are a much more complex problem than a "simple" chain reaction. The Oklo reactor in Gabon was a natural uranium reactor, back when the U-235 abundance was high enough to sustain the reaction.

I really doubt it. The actual fissionable uranium is only a small percentage of all of the uranium in the ore, and also, the uranium in the ore is not concentrated either.

Fissile. All of the uranium is fissionable - capable of undergoing fission. But it's the U-235 that is fissile, or capable of a sustained chain reaction.

here's a quick question, hope someone looks here!

if you have a ballon full of hydrogen and ignite it it will blow up

if you ignite the H given off by an experiement, say Mg + HCl then it will not blow up

why is this? is it to do with quantities of the gas?

[YT2095]

CM^3 of gass potential.

the balloon has considerably more hydrogen at its disposal all at once, than the misserable quanties given off in an Mg HCl(aq) reaction.

here`s another quicky:

what`s the difference between Psychology and Psychiatry?

[5614]

the spelling!!!... nah...

Psycology: scientific study of human/animal behavior
Psychiatry: diagnosis and treatment of mental disorders/conditions

[5614]

ok...

when you write a chemical symbol like Mg you could write Mg (s) coz Mg is a solid... H2O is a liquid so (l)? but (aq) is sumin disolved in water... so how would you write H2O (??)..... prob (l) but im not 100% sure!?!?!?

I could be wrong, but I'm fairly certian psychiatrists are considered MDs, while psychologists aren't. I think psychiatrists, in practice, do more with serious disorders such as schizophrenia, while in general psychologists do more counseling and other things. That brings to mind a question of my own, can psychologists prescribe drugs? I know that psychiatrists can, but I wasn't certain if both could.

what are NIBS ?

Neodymium-Iron-Boron.

[YT2095]

magnets made from a composite of Neodyum, Iron and Boron.

for more information, have a look here: http://www.google.co...2NIB+magnets%22

Cool. Where do i get some?

Are they like the ones from a HDD.

It says on here to buy them from Edmund Scientific, but thats in the US.

sorry I seem to have posted all of this in the wrong Thread, it should be in 'Breaking Magnets', not sure how I did that one guys, sorry about that.

[ed84c]

Lance I just pointed out that i could not buy from as Edmund Scientific is in the US and as a result giving me a number of links to sites in the US is not very helpful :-)

[YT2095]

to answer your question in post #54, you can get 2 lovely NIB magnets from most HDDs and the older the drive the bigger the magnet as a general rule :)

[5614]

well to add to what YT said i can only say in the case of two HDDs, one 14 years old had 4 NIB mags, each one about 1cm across and 0.5cm high.... compared to one which was about 5 years old, that just had two big ones, about 2cm across and 0.8cm high.

again, im not saying YT is wrong because i dont know, but from the two ive looked at, that's what ive seen.

No, your posts were moved here because you were taking someone else's thread off-topic.
