| 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. |
