dosimetry /do·sim·e·try/ (do-sim´ĕ-tre) scientific determination of amount, rate, and distribution of radiation emitted from a source of ionizing radiation, in biological d. measuring the radiation-induced changes in a body or organism, and in physical d. measuring the levels of radiation directly with instruments.
dosimetry [dōsim′ətrē] Etymology: Gk, dosis, giving, metron, measure 1 the determination of the amount, rate, and distribution of radiation or radioactivity from a source of ionizing radiation. 2 the accurate determination of medicinal doses based on body size, sex, age, and other factors. dosimetry (dōsim´etrē), n the accurate and systematic determination of the amount of radiation to which an animal or person has been exposed during a given period. dosimetry scientific determination of amount, rate and distribution of radiation emitted from a source of ionizing radiation. dosimetry Radiation physics The formal science that measures and calculates doses and format of radiation to be administered to a Pt with a disease requiring RT, in particular cancer.

The ratio of lung cancer risk coefficients in the LSS and in groups of underground miners is close to the value suggested by the latest International Commission on Radiological Protection (ICRP 1994) model of lung dosimetry (Birchall and James 1994; Little 2002b). Besides tables, the author uses boxes and step-boxes for quick review of information such as the physiological effects of a modality and dosimetry. In addition, the VIISta 810 HP provides precise total incident angle and dosimetry control to enable tighter distribution of electrical device parameters and a 50% reduction in contamination to enhance device yields. |
