WebJun 23, 2024 · More accurately, bioavailability is a measure of the rate and fraction of the initial dose of a drug that successfully reaches either; the site of action or the bodily fluid domain from which the drug’s intended targets have unimpeded access. WebQuantities 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 absorbed dose, which in the CGS system has the unit rad.

This paper presents a microdosimetric approach to measuring the biological dose, which was redefined to be derived from microdosimetric quantities …
WebMar 20, 2024 · 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 ). For practical purposes, 1 R (exposure) = 1 rad (absorbed dose) = 1 rem or 1000 mrem (dose equivalent).
WebNational Center for Biotechnology Information 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.
