建筑材料内照射指数、外照射指数稳定性研究

摘要

在同实验室、同测量人员、同测量设备、同测量时间、同实验室温度和湿度的条件下,分别取制不同的A样品、B样品和C样品,并从取制样品当天时间开始检测,以间隔一天的时间每天测量不同样品一次,并计算记录间隔22天每天不同样品的镭-226、钍-232、钾-40比活度,分别计算其不同内照射指数、外照射指数,从理论方面解释建筑材料中内照射指数、外照射指数稳定性.%With the same surveyors, the same measurement equipment, the same measurement time, the same laboratory conditions of temperature and humidity in the same laboratory, taking the different samples of A, B and C, measuring the samples from the time of day the system began to take test in interval of day and calculating the interval of 22 days record in different samples of radium-226, thorium-232, potassium-40 specific activity.Calculating the different internal and external exposure index to explain these stabilities in building materials in theory.
