CPC G01T 1/26 (2013.01) [G01T 3/00 (2013.01)] | 23 Claims |
1. A radiation detector, comprising:
(a) a first insulating substrate including boron nitride that includes more 10B than 11B, which undergoes a change in an electrical property when subjected to ionizing radiation;
(b) a first conductive film disposed in relation to a surface of the first insulating substrate, the first conductive film having a resistance that is at least partially a function of a state of the electrical property of the first insulating substrate;
(c) a first resistance measuring device for measuring resistance across the first conductive film, wherein the resistance measured by the first resistance measuring device indicates an amount of ionizing radiation to which the first insulating substrate has been subjected;
(d) a second insulating substrate including boron nitride that includes more 11B than 10B;
(e) a second conductive film disposed on a surface of the second insulating substrate, the second conductive film having a resistance that is at least partially a function of a state of a predetermined property of the second insulating substrate;
(f) a second resistance sensor for measuring resistance across at least a portion of the second conductive film; and
(g) a comparison circuit that compares resistance measured by the first resistance sensor to resistance measured by the second resistance sensor, thereby indicating an amount of radiation exposure that is attributable to neutrons.
