3 terminology and units of measurement

3.1 Terms 3.1.1 tissue phantom ratio (tissue-phantomration) TPR Distance from radiation source to the detector (SCD) constant, on a plane perpendicular to the beam axis and the radiation detector comprising, in order As the center of the radiation field detector takes a certain value, at different depths mold body, the detector measured the ratio of the absorbed dose, Is TPR. 3.1.2 treatment level dosimeter (dosemeterwithionizationchambers) Therapeutic levels of ionization chamber dosimeter based dose detector measuring instruments. Treatment usually consists of ionization level dosimeter Room and balance cap, measuring unit and stability testing device components. 3.1.3 Calibration depth (calibrationdepth) Calibration depth in phantom for radiation absorbed dose calibration measurement, effective measurement point where the detector depth. 3.1.4 Calibration factor (calibrationfactor) Instrument calibration factor is a measure of the amount of conventional true value divided by the instrument indication (mutatis mutandis) the quotient obtained.
