WebThe unit for the quantity equivalent dose is the sievert (Sv). Thus, the relation is. equivalent dose (in Sv) = absorbed dose (in Gy) x radiation weighting factor. In the older system of units ... Webnormal biological processes; or (3) cells incorrectly repair them-selves resulting in a physical change. The exact effect depends on the specific type and intensity of the radiation exposure. The amount of energy deposited in material by ionizing radiation is called dose. Biological doses are measured in units called rems. Geiger counter.

WebMar 9, 2024 · Dose equivalent A measure of the biological damage to living tissue as a result of radiation exposure. Also known as the " biological dose," the dose equivalent is calculated as the product of absorbed dose in tissue multiplied by a quality factor and then sometimes multiplied by other necessary modifying factors at the location of interest. WebThey are typically evaluated either as H* (10), which describes a personal equivalent dose measured at 10 mm depth of a reference sphere consisting of soft tissue equivalent according to the ICRU.
