摘要：
A dual instrument technique, employing a neutron area survey meter and a tissue-equivalent proportional counter, has been developed to improve the measurement of neutron dose equivalent rates in workplace fields. A simple algorithm estimates the ambient dose equivalent response of the area survey meter from the ratio of the dose equivalent rates measured by the two instruments. This estimate can then be used to adjust the reading from the area survey meter, providing a better measure of the neutron ambient dose equivalent rate in the workplace. The technique was tested on 225 spectra from the neutron spectrum catalogue SPKTBIB.
