Usefulness of laboratory neutron fields.
A moderator-type neutron survey meter, intended for radiation protection use at a nuclear power plant, was tested in five laboratory neutron fields, including neutron fields that resemble ones found in some reactor workplaces. Calibration constants (counts Sv(-1)) and responses (ratios of measured to reference values of ambient dose equivalent) were determined by measurement for each neutron field. Theoretical calibration constants were calculated for each field using a response function from the literature. These theoretical calibration constants were consistent with ones determined from measurement. Theoretical calibration constants were also calculated for several power-plant workplace neutron spectra. The range of calibration constants determined provided some insight into the amount of over-response and under-response that this particular survey meter would be likely to give when used in the intended workplace. Values for the calibration constant were suggested.
