Abstract: In order to study the feasibility of bubble neutron detector (BND) to neutron personal dosimeter in nuclear well logging, radiation levels at points concerned inside and outside the radiation source vehicle for nuclear well logging were measured by using both domestic BNDs and neutron ambient dose equivalent meter (LB6411). The results show that there are no statistical differences both between the measured data from BND and LB6411 while neutron source loaded in the vehicle alone and between the data from BND at neutron-γ source loaded and without γ-source loaded in vehicle, respectively. The BND’ dose response performance was calibrated at two field conditions, and the relative deviation between the calibrated sensitivity factors is 7.4%. It is clear that the BND can be used in measuring neutron radiation in neutron-γ mixed field, and the dose response is independent of neutron energy within a certain energy range. And the applicability of BND to neutron personal dose monitoring in nuclear well logging is experimentally validated.
