Responses of commercially available neutron electronic personal dosemeters in neutron fields simulating workplaces at MOX fuel fabrication facilities

Tsujimura, Norio   ; Yoshida, Tadayoshi ; Takada, Chie 

The authors investigated the performance of three commercially available electronic personal dosemeters (EPDs) in evaluating neutron dose equivalents and discussed their suitability to work environments in MOX fuel fabrication facilities. The EPDs selected for this study were NRY21 (Fuji Electric Systems), PDM-313 (Aloka) and DMC 2000 GN (MGP Instruments). All tests were conducted in moderated $$^{252}$$Cf neutron fields with neutron spectral and dosimetric characteristics similar to those found in MOX fuel facilities. The test results revealed that all three models demonstrate a performance within a reasonably acceptable accuracy (a factor of 2) in practical use. The test results also suggested that the accuracy of some EPDs can be improved with a judicious selection of calibration sources.
