An analysis of effectiveness and accuracy of ionization, semiconductor and thermoluminescent detectors used in total body irradiation

An analysis of three types of detectors used for dose calculation and verification during total body irradiation (TBI), procedure is presented. Doses were traced in ten points representative for body anatomy on beam entry and exit. To verify the calculated doses, a set of semiconductor, thermoluminescent and ionization detectors has been applied. Application of each type of detector has been discussed and their response to dose in TBI condition evaluated. The accuracy of dose determination between 2.6% to 3.3% on entry and 5.8% to 7.7% on exit was achieved depending on the type of detector. (author). 7 refs., 1 tab., 1 fig
