Objective To research and assess radon concentration and radioactivity level of part coal mine in Guizhou province.
目的研究和评价贵州省地下煤矿氡气浓度和放射性水平。
Methods the measurable range was broadened through: Lowering of the specific radioactivity of the labelled antigen, increasing the concentration of the anti-serum and improve the curve fitting method.
方法：通过降低标记抗原的比放射性，提高抗血清的浓度，改进曲线拟合方式等方法，扩大测定范围。
