Which of the following is the most important biological measure of radiation?

Question

curie
rad
rem
roentgen

Answer 1

"Different units of measure are used depending on what aspect of radiation is being measured. For example, the amount of radiation being given off, or emitted, by a radioactive material is measured using the conventional unit curie (Ci), named for the famed scientist Marie Curie, or the SI unit becquerel (Bq). The radiation dose absorbed by a person (that is, the amount of energy deposited in human tissue by radiation) is measured using the conventional unit rad or the SI unit gray (Gy). The biological risk of exposure to radiation is measured using the conventional unit rem or the SI unit sievert (Sv)."

Answer 2

I would say rem (roentgen equivalent man). I seem to remember from my days as a nuclear reactor operator that this is a measure of the amount of damage a given amount of radiation can do to you. And, that would seem to be the most important biologically.

Answer 3

That's the curie.
