Question

List the 3 measurements that are more appropriate for measuring absorbed doses for radiation or occupational dose?

1. Gray (Gy).
2. Rad.
3. Sievert (Sv).

Answer 1

The Gray (Gy), Rad, and Sievert (Sv) are measurements used to evaluate absorbed doses for radiation, where the Gray measures energy absorbed, Rad is used in medicine, and Sievert accounts for biological effects.

Step-by-step explanation:

The three measurements that are more appropriate for measuring absorbed doses for radiation or occupational dose include the Gray (Gy), the Rad, and the Sievert (Sv). The Gray is the SI unit of absorbed dose, defined as the absorption of one joule of radiation energy per kilogram of matter (1 Gy = 1 J/kg). The Rad is a non-SI unit still used primarily in medicine, where 1 rad equals 0.01 Gy or 0.01 J/kg of tissue. The Sievert is the SI unit measuring the effective dose, accounting for both the energy absorbed and the biological effects of the radiation type involved, with tissue damage units like rem being related to Sv by incorporating a biological factor known as the RBE (for relative biological effectiveness).
