ORIGINAL: pinkpleasures quote:
It's a physics term. It's the length of time that a radioactive element takes to lose half of its radioactive output. Since the process is a halving, an element may be dangerous for a number of half-lives JohnWarren Really? An element just keeps on halving, ad infinitum? pinkpleasures[/font][/size][/color] Simple explanation: Until there are just two radioactive molecules in the sample. Then one decays and a half life later the other decays and it's over. Actually, when the number of molecules of the radioactive isotope get really low, the neutron flux is such that a normal cure no longer applies.
