WebThe 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). Measuring Emitted Radiation Webgray: Gray (Gy) is the unit in the International System of Units used to describe absorbed radiation dose. It describes a specific amount of energy absorbed in a medium (human tissue, for example). In the traditional units, the rad describes absorbed radiation dose. One gray is equal to 100 rad. cracker barrel christiansburg https://tammymenton.com
