Calculate the effective radiation dosage in sieverts for a 57 57 ‑kg person who is exposed to 4.2 × 10 9 4.2×109 particles of alpha radiation. Only 81 % 81% of the radiation is absorbed. Assume each alpha particle has an energy of 6.1 × 10 − 13 6.1×10−13 J and that the RBE of the alpha particles is 15 15 . Note that RBE is sometimes called the quality factor ( Q Q ).
