WebA radiation survey meter measures the radiation hazard one is exposed to. Portable and hand-held, these are devices that detect and measure alpha, beta, and gamma radiation. These are battery-powered and of low weight for ease of use. Radiation survey meters are used in and around laboratories. Also in other areas where radioactive materials or ... The roentgen equivalent man (rem) is a CGS unit of equivalent dose, effective dose, and committed dose, which are dose measures used to estimate potential health effects of low levels of ionizing radiation on the human body. Quantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation, which is primarily radiation-induced cancer. These quantities are derived from absorbe…
