u dun really need alot of lessons on it i dun think... all u gotta learn it the 3 types of radiation, sea of stability, the p to n ratio that makes a nuclei stable, an eg in med/industry use etc etc...

uhm, perhaps u need more than 2 lessons... =p blehz

Hmm so do you need to know the difference between beta - and beta + radiation?

 

[smegthehead]

we did an experiment for nuclear chemistry. we got a geiger meter and measured the aveage amount of radiation detected at certain distances for the following isotopes:

Strontium-90 (beta emitter)
Polonium-210 (alpha emitter)
Cobalt-60 (gamma emitter)

however they were in extemely tiny quantities and were only handled by our chem teacher

No, you don't.

there's a difference?

Yep beta - occurs when there is too many neutrons, a neutron decays into an electron + a proton + an anti-neutrino.

Beta + radition occurs when there is too many protons.
A proton decays into a positron+neutron+a neutrino.

well, if u do physics, u might as well know it... u gotta learn soemthing on pet i fink... it ain't that hard to remember any way... infact, rememberin b + and b- together is much more efficient way to remember the nuclear decay i fink...

Well dont you have to go through all ways they become radioactive in chem anyway (ie too many neutrons and too many protons) its a bit stupid how you only learn about one beta radiation since it only occurs when there are too many neutrons.

yea.... i cannot agree more to that... =p blehz

You make a good point but I would point out that positron decay is comparatively rare (esp. in naturally occuring radioisotopes), and the last thing the chem syllabus needs is more content!

YES its too bloody full as it is
