Why radioactive elements should be eliminated in earth?

Question

plz tell me plzz.......

Answer 1

It seems you've asked this question four times, and you've already got some good answers for what seems like a homework question by a misguided teacher.

First of all radioactive elements are not necessarily bad, and second of all there are dozens of naturally occurring radioactive elements. When most non-technical people think of radioactive elements, they think immediately of uranium. Fact is, way less than 0.1% of the gamma radiation on the earth's surface is caused by uranium. Most gamma radiation is solar radiation from the sun. So even if you were to eliminate radioactive elements, it would not significantly change the amount of gamma radiation (or even alpha and beta particles) that we are subjected to every second of our life.

I can't imagine any reason why radioactive elements "should" be eliminated, and on top of that it is absolutely impossible to achieve that. Radioactive elements that occur in nature include uranium, carbon, thorium, potassium, iodine, bismuth, and lead.
