The element lead, which is sometimes used as a shielding material, has four primary isotopes Pb-204,


The atom transfer, which is rarely used as a shielding material, has four chief isotopes Pb-204, Pb-206, Pb-207, and Pb-208 after a while a relative abundance of 1.48%, 23.6%, 22.6%, and 52.3%, respectively. Using these percentages, indicate the minute consequence of naturally occurring transfer, which is rarely used to establish radiation shields.
