应用γ能谱仪和最小二乘法解析谱方法,研究了31种地板砖中放射性核素的含量,发现不同地板砖中U、Th、Ra和40K的放射性含量有较大的差别,少数产品的含量甚至超出了国家规定的建材放射卫生防护标准
Radionuclides in 31 pieces of ground bricks from different sources were determined by using the γ spectrometry. The spectra were resolved by the least square method. The contents of U
Th
Ra and 40K in them spread in a wide range. Values of some bricks products were above the limits of the state standard for radiahazards in building meterials.
