 dosimetry medical definition
/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 is the study, measurement, method of measurement, or instrument of measurement of radiation dose. Dosimetry often refers to the status of wearing a personnel badge that measures and monitors dose. DEFINITION. Dosimetry is the study, measurement, method of measurement, or instrument of measurement of radiation dose. Dosimetry often refers to the status of wearing a personnel badge that measures and monitors dose. It may also refer to dose history and the records where dose history is maintained. Medical Dosimetry. Medical dosimetry is a part of the field of radiation oncology involving knowledge of advanced mathematics, radiobiology, physics and anatomy. In order to shrink or eliminate tumor growth, some patients receive limited doses of radiation internally or externally. 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. See Definitive radiation, EPR dosimetry, Radiation. Medical Definition of DOSIMETER. : a device for measuring doses of radiations (as X-rays). — do·si·met·ric \ˌdō-sə-ˈme-trik\ adjective. — do·sim·e·try \dō-ˈsim-ə-trē\ noun, plural do·sim·e·tries. /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. an area of applied physics that studies the physical values that characterize the effect of ionizing radiation on natural objects (animate and inanimate)—in particular, radiation doses—and the methods and instruments for measuring these amounts. The Dosimetry and Medical Radiation Physics (DMRP) section is responsible for the quality assurance (QA) aspects of the use of radiation in medicine to ensure safety and effectiveness, and deals with the science and technology involved in this area.
