If a $60 \mathrm{~kg}$ person received a biologically equivalent dose of 1.7 rem of radiation with an RBE of 1.1, what was the total energy absorbed by the person?

Question

Quizplus · Accepted Answer

The total energy absorbed can be calculated using the formula $E = \frac{D \cdot m}{RBE}$, where $E$ is the energy in joules, $D$ is the dose in rems (1.7 rems), $m$ is the mass in kilograms (60 kg), and $RBE$ is the relative biological effectiveness (1.1). First, convert the dose from rems to Sieverts (Sv) because 1 rem = 0.01 Sv, so 1.7 rems = 0.017 Sv. The energy absorbed in joules (J) is given by the formula $E = D \cdot m$, where $D$ is in Sv, so $E = 0.017 \cdot 60 / 1.1$, which equals approximately 0.93 J.
