WebSep 14, 2024 · What are biological doses measured in? December 15, 2024 September 14, 2024 by Alexander Johnson Units for dose equivalent are the roentgen equivalent man (rem) and sievert (Sv), and biological dose equivalents are commonly measured in 1/1000th of a rem (known as a millirem or mrem). WebBiological dose equivalents are measured in 1/1000th of a rem (millirem or mrem). Put simply, 1 R (exposure) = 1 rad (absorbed dose) = 1 rem or 1000 mrem (dose equivalent). Because alpha and neutron radiation are more damaging, the dose equivalent is larger than the absorbed dose, whereas the dose equivalent is the same as the absorbed dose for ...
