Title:
中性子線・γ線弁別測定法
Document Type and Number:
Japanese Patent JP6947389
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thermal fluophor capable of discrimination measurement of neutron beam and gamma beam with corresponding to radiation dose range of BNCT with simple device at low cost stably, and a neutron beam and γ beam discrimination measurement method.SOLUTION: There is provided a thermal fluophor for discrimination measurement of neutron beam and gamma beam mainly containing AlOand containing a thermal fluophor component as an addition component. There is provided a neutron beam and gamma beam discrimination measurement method using the thermal fluophor, by preparing the thermal fluophor described in 1 and an object thermal fluophor mainly containing BeO, irradiating radiation where the neutron beam and the gamma beam are mixed to both of the thermal fluophor and the object thermal fluophor for a plurality of times with changing irradiation time, measuring thermal fluorescence property of the thermal fluophor and the object thermal fluophor, calculating integrated fluorescence amount of both of the neutron beam and the gamma beam of the fluophor, grasping radiation dose of the γ beam by further assigning the thermal fluorescence property of the thermal fluophor and the object thermal fluophor into the following formula to calculate γ beam fluorescence amount, and grasping radiation dose of the neutron beam by reducing the γ beam thermal fluorescence amount from the integrated fluorescence amount.SELECTED DRAWING: None
