Abstract:
Objective To understand the dosimetric performance of energy differential type dosimeter.Methods A differential type dosimeter (CTLD-J4000) was chosed to conduct a series of dosimetric performance tests,including linear standard curves,relative response to mean photon radiation energy and incidence angle.Results The linear correlation of CTLD-J4000 energy differential dosimeter was good,with the average photon radiation energy response deviation within ± 20％ and the maximum incidence angle response deviation of 10％.The energy identification could be achieved according to the energy reference value provided by the manufacturer to a certain extent.Conclusions Further experiments are needed to find out the factors influencing measurement result from different dose values and incidence angles.
