- Abstract
- Simulated workplace neutron fields have been developed at the Korea Research Institute of Standards and Science (KRISS). An Am-241-Be neutron source and a cylindrical moderator composed of stainless steel and heavy water were installed in a 10-cm-thick concrete block with dimensions of 150 x 120 x 120 cm(3). The neutron energy spectrum at a distance of 66.5 cm was measured using a Bonner sphere spectrometer and was found to agree with the spectrum obtained from the Monte Carlo N-Particle Extended simulation to within 5%. The neutron fluence-to-personal dose equivalent conversion coefficients were (20.8-43.6) pSv.cm(2) and were thus in good agreement with those of reactor fields. The results showed that the KRISS-simulated workplace neutron fields can be used for performance tests and the calibration service of neutron personal dosemeters.
