Tests on human subjects along the East Coast of the United States in 1965 and 1966, following the era of atomic bomb testing, revealed quantities of about 3.51 pCi of plutonium radioactivity (alpha radiation) in a test subject. A 55-kg person is exposed to this radiation for 1.00 year (365 days). If each alpha particle deposits 8.00×10-13 J. (a) what is the number of rads absorbed by the person? (b) What is the effective does in rems, if the RBE for alpha radiation is 10? 9.29 x 10-2, 9.29 x 10-1 5.96 x 10-6, 5.96 x 10-5 7.34 x 109, 3.12 x 10-8 6 x 10-6, 5.96 x 10-7 3.12 x 10-5, 3.12 x 10-6
