[Dose and dose distribution close to Ir-192 sources].

Abstract

A report is given on dose measurements performed in the radiation field close to Ir-192 sources. The dose was measured at a distance of 2 to 8 cm in the air and in a phantom with ionization chambers. Radiachromic foils were used in order to determine the dose distribution surrounding the sources immediately. The measurement results were compared to model calculations and show a good conformity.
