摘　　要：通过对水氡观测资料分析认为,标定测氡仪器时,若按《规范》要求当标定的新-原K值相对偏差大于5%时才能使用新K值来计算水氡浓度,容易产生误差积累,出现水氡测值偏低、观测数据"台阶"、及平行样经常超差等现象。应用"无论新-原K值相对偏差是否大于5%都启用新K值"的方法对以往观测资料进行重新计算,与原来数据对比大大降低误差的积累,使观测数据更接近其真值。Based on the analysis of observed radon data,radon concentration can be calculated by using the new K-value which is required that the error between the original and new K-value is greater than 5%.This method might be easy to produce error accumulation,lead to data step,lower measured values and the phenomenon of out-of-tolerance for parallel sample.This paper used the new K value to recalculate the previous observation,no matter the difference between the new K value and original K-value is greater than 5%.The results show that this method can greatly reduce the accumulation of errors and the observation data are closer to its true value.
