Excerpt: | |  Roentgen (R) refers to the amount of radiation dose delivered to the body
A rad is the unit of absorbed dose A rem is the unit of any radiation dose to body tissue in terms of its estimated biological effect For x-ray or gamma-ray radiation, roentgens, rems and rads are virtually the same For particulate radiation from radioactive materials, these terms may differ greatly (eg, for neutrons, 1 rad equals 10 rems) In the Système International (SI) nomenclature, the rad has been replaced by the gray (Gy), and 1 rad equals 0.01 Gy = 1 cGy The SI replacement for the rem is the Sievert (Sv), and 1 rem equals 0.01 Sv |
