rad

Rad, short for "radiation absorbed dose," measures the amount of energy from ionizing radiation that is absorbed per unit mass of a substance, usually measured in gray (Gy). Essentially, it quantifies how much radiation energy is deposited into tissues or materials, which can be important for assessing potential health risks or controlling radiation exposure. Higher rad values indicate more energy absorbed, potentially leading to greater biological effects like tissue damage. Rad is used in medical, industrial, and research settings to monitor and limit radiation exposure for safety and effectiveness.
