【摘要】 用活性炭法测氡析出时,由于介质中通常含有一定量的水,因而活性炭在吸附氡的过程中同时也吸附了一定量的水,其吸水的多少与介质的含水率有关。活性炭吸水会影响对氡的吸附,当吸水到一定程度时会对测量结果产生显著的影响。本文给出了活性炭法测氡析出率的湿度修正实验方法,并给出了混凝土、石膏板介质表面的析出率修正实验数据。更多还原

【Abstract】 By reason of the exhalation medium contains a quantity of the water,the activated charcoal will absorb some water while measuring radon exhalation rate with activated charcoal.The adsorption efficiency of activated charcoal for radon would be changed if activated charcoal absorbs water,and the effect to measured results become obvious when activated charcoal absorbs a mass of water.The experiment method of humidity correction in the radon exhalation rate measurement by the method of the activated charcoal absorption—γspectrometry is given in this paper,experimental data for concrete and gypsum boards surface are also given.更多还原
