Abstract:
Objective:To compare the test results of domestic and imported eye lens and ring dosimeters, and master
some dosimetric performance indexes of eye lens and ring dosimeters.
Methods:According to IEC 62387—2012 and GBZ 128—2019, the performance of the eye lens dosimeters and ring dosimeters with the domestic thermoluminescence detectors
were compared with the imported thermoluminescence detectors in photon response. The dose response deviation of the im-
ported eye lens dosimeter and imported ring dosimeter was studied under the same irradiation condition. The difference of
linear response between imported ring dosimeter and domestic ring dosimeter was studied under the same irradiation condition.
Results:The same dose was irradiated to domestic and imported thermoluminescence detectors in the imported eye
lens and imported ring dosimeters, and the linear correlation coefficient all met R2 > 0.999. The maximum response devi-
ation of the imported eye lens dosimeter and ring dosimeter was less than 10.0% for the same dose. Two kinds of imported
ring dosimeters and one kind of domestic ring dosimeter were irradiated with the same dose, and the linear correlation coefficient all met R2 > 0.99.
Conclusion:Both domestic detectors and imported detectors can meet the needs of monitoring re-
quirements. There was no obvious difference in linear response between imported ring dosimeter and domestic ring dosimet-
er. The repeatability of imported eye lens dosimeter and imported ring dosimeter met the performance requirements of the dosimeter.
