The radioactive decay of ----------------------------------- is the single greatest source of human exposure to radiation. (a), Ozone. (b), thorium. (c), radon. (d), hydrogen. (e),uranium.
Homework Answers
The radioactive decay of ---ozone--- is the single greatest source of human exposure to radiation.
Ozone form a layer in stratosphere that prevent to human and other lives from UV rays of sun. Ozone has little half life it degrades in O2 and atomic oxygen.
O3----> O2 + O
O2 + O ----> O3
O3 + O ------> 2O2
O2 -------> O +O (photolysis hv)
