摘要
一种新型的无动力累积氡监测器只需在扩散室内安置一片新型CR-39(DPA)固体核径迹探测器便可制成。统计分析表明,它的可测下限为2.2Bq·m^(-3)·月。这种装置灵敏可靠、使用方便,且适用于各种氡监测场所。
A now type of passive integrating radon monitor which makes use of a new CR-39 (DPA) track detector inside a diffusion chamber has been developed. A statistical analysis of sensitivity shows that reliable readings can be made down to a 2.2Bq·m-3 . month exposure. With a high sensitivity and reliability, this system can be conveniently used in a variety of radon monitoring situations.
