Two technicians in a nuclear laboratory were accidentally exposed to radiation. If one was exposed to $8\mathrm{mGy}$ and the other to $5rad$. which technician received more radiation?

Two samples of a radioisotope were spilled in a nuclear laboratory. The activity of one sample was $8\mathrm{kBq}$and the other $15\mathrm{mCi}$. Which sample produced the higher amount of radiation?

a) The recommended dosage of iodine-$131$is $4.20\mathrm{μ}\mathrm{Ci}/\mathrm{kg}$of body mass, How many microcuries of iodine-$131$ are needed for a $70.0$-kg person with hyperthyroidism?

b) A person receives $50rad$of gamma radiation. What is that amount in grays?
