dosimetry

 [do-sim´ĕ-tre]
scientific determination of amount, rate, and distribution of radiation emitted from a source of ionizing radiation.

do·sim·e·try

(dō-sim'ĕ-trē),
Measurement of radiation exposure, especially x-rays or gamma rays; calculation of radiation dose from internally administered radionuclides.

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
