Abstract

A bubble-damage polymer detector, which operation principles are based on vaporization of superheated liquid drops by interaction with radiations, is developed for neutron dosimetry. The detectors are fabricated by dispersing the superheated liquid drops of Freon12 into transparent and elastic polymer made of acylamide and glycerine. The bubbles formed by neutron irradiation are immediately visible. The neutron sensitivity of the detectors is 4-7 bubbles/10$\mu$ Sv for Am-Be neutrons.

중성자선량측정을 위하여 방사선과의 상호작용으로 인한 과열된 액체의 기화를 원리로 하는 bubble-damage polymer detector를 개발하였다. acrylamide와 글리세린으로 만든 중합체에 과열상태의 Freon12 액체방울을 분산시켜 검출기를 제작하였으며 중성자 조사에 의해 형성된 기포는 즉각적인 육안 관측이 가능하였다. 검출기의 중성자감도는 Am-Be중성자에 대해 $4{\sim}7bubbles/10{\mu}Sv$이었다.
