1. In a nuclear accident, a lab worker receives a dose of D rad of radiation of X-rays having anRBE of 1. Suppose the worker was exposed to the same amount of energy from alpha particles(1 point)having an RBE of 20. What would the exposure have been?O20D radODrad20O0.20D radOD rad2. A 5.0 g sample of irradiated tissue receives an absorbed dose of radiation that measures 6.25 (1 point)rad. How much energy does the tissue receive?06.3 x 10-4 J(1.8 x 10 4 J03.1 x 10-4 J(8.0 x 10-4 J3. Which quantity is measured using a unit known as the Sievert (Sv)? (1 point)Oequivalent doseOrelative biological effectivenessOabsorbed doseOreleased dose
