The difference between the rad and the rem is

Question

Quizplus · Accepted Answer

The rad (radiation absorbed dose) is a unit of measurement that describes the amount of energy absorbed by a material due to radiation. The rem (roentgen equivalent man) is a unit of measurement that takes into account the type of radiation and the effect it has on biological tissue.

Therefore, choice B is incorrect as the rad only describes the amount of energy absorbed by a material due to radiation and does not take into account the type of radiation.

Choice D is also incorrect as the rem is not a rad per kilogram, but rather a unit that includes both the absorbed dose and the type of radiation.

Choice A and E are incorrect for the above-mentioned reasons.

Hence, the correct choice is C.
