Hi there everybody,
I was studying radioactivity searching a lot on internet but i didn't get much about what is implicit on the study.I read about half-life,radiations alpha,B and Y but still don't understand what is it exactly.Let me formulate better the question,but first i must tell you guys that my english is not one hundred percent ,ok?
It is known that a radioactive element has a half-life,some it is nothing but less than a second and some are about billions of years.Until this point the question is not yet answerd: a element has a certain amount of atomic mass,which means that a element as a uranium,for example,can not just free alpha radiation every second or minute once it has less than tree hundred protons plus neutrons.So,what kind of radiation is libareted from atoms as these and if there's a equation that rules each moment a radioactive atom will liberate an alpha radiation?
