摘要：

In order to assess the feasibility of neutron bubble detectors (NBD) for monitoring neutron doses in radiation fields of nuclear well logging, neutron dose levels at several positions inside and outside a truck transporting radiation sources for nuclear well logging have been measured and analyzed using both a NBD and a neutron ambient dose equivalent rate meter (NADERM). The relative difference of the sensitivities between a NBD calibrated by a certified Am-241-Be radiation source and a standardized NADERM is 7.4%, well within the counting statistic uncertainties, indicating that the NBD response is similar to the NADERM for this neutron field, and thus is an appropriate dosimeter for this application. The results of statistical analysis show that NBD are reliable for neutron dose monitoring in both pure neutron and n-gamma mixed radiation fields of nuclear well logging.
