Abstract

In this work we studied the response of two different Victoreen® instruments as a function of the exposure rate, the instrument orientation and photon energy. The rate dependence for both instruments is of the order of 8 % over the range of exposure rates tested (0.5 mR/h to 1000 mR/h). Regarding the instrument orientation dependence investigation, a significant difference is observed between the two instruments. While the Victoreen® 451P shows no significant dependence with instrument orientation, the Victoreen® 451P-DE-SI shows a significant dependence of up to 20 % between the three different orientations. Finally, the energy dependence measurements of both instruments reveal the instruments measure lower exposure rate values compared to the reference values for the low energy x-rays by about 20 %. While, for the 60Co gamma-ray beam measurements, both instruments are about about 5 % higher than the reference value.
