摘    要:铀矿的退役处理是放射性固体废物处理的一个重要领域,研究退役铀矿的放射性水平及其影响因素具有重要的意义。对某矿山的11个废石堆进行表面氡析出率的实地测量,探讨废石堆表面氡析出率的影响变化规律,提出平地堆放型较依山堆放型的析出率高且更不稳定,建立了废石的粒度大小、在堆表面所处的位置和废石中u,Ra的活度与表面氡析出率的相关性,并建立了表面氡析出率与气温、地温、气压、相对湿度、降雨等气象因素的相关规律,为铀矿山退役治理提供理论依据。

关 键 词:废石堆氡析出率变化规律

Abstract:The retirement of uranium ore processing is an important area of radioactive solid waste treatment, and the Study of radioactivity level and influencing factors of decommissioning uranium is very importance. It explores the change rule of the waste dump surface radon exhalation rate through on-the-spot measuring the surface radon exhalation rate of 11 waste dump of a certain mine. It is concluded that the radon exhalation rate of the ground type is higher and more unstable than stacked up to the mountain type, and the relationship of the particle size, the position of the waste rock surface and the U, Ra activity in waste stone with the radon exhalation rate,and es tablished the radon exhalation rate related laws between surface temperature, ground temperature, pressure, rela- tive humidity, rainfall, and other meteorological factors, Provides a theoretical basis for guiding the management of uranium mine decommissioning.
Keywords:waste dump  radon exhalation rate  change regulation
