Either something was created or it always existed. If radioactive matter always existed than wouldn't we be at a point where the radioactivity was barely perceptible? The claim is that the Universe is billions of years old. Although half-lifes are long, they are not in the billion year range. Following this 'half-life' concept out, that would eventually mean a Universe virtually radioactive -ree anyway. By the way- It had to already exist before it could 'Big Bang'....
This draws over into thermodynamics and the laws of entropy. Understanding such laws, I can inform
you that your conclusions on the subject are inaccurate.
Radioactive isotopes are being created right now everywhere from in the nuclei of stars to our own
atmosphere where Carbon-14 is created when cosmic rays interact with atmospheric nitrogen.
I agree, but in effect my point remains. All the nuclear material we will have acess to should eventuallly become almost nil in activity. The isotopes being created by the stars is a non-issue. It will remain there.
