A study of experimental measurements of dosimetric parameters in HDR IR-192 source.
Thermoluminescent dosimeters have been used to perform dosimetry measurements for the widely used Ir-192 microSelectron-HDR source with an improved polystyrene phantom. Radial dose functions and anisotropy functions, main parameters of 2D dose-rate formalism from the TG-43U1 protocol, have been obtained experimentally. Measurement results are compared with that of the Monte Carlo calculations reported, and no difference has been found between them.
