摘　　要：以本地区地下水和世界其他地区天然水典型放射性数据结果为研究对象,SPSS辅助数据分析,首次系统阐述了天然水中^(40)K与总β的关系。^(40)K常常是天然水总β的主要贡献者:多数情况下,天然水中^(40)K与总β相关性具有统计学意义(P<0.05),甚至明显具有统计学意义(P<0.01);^(40)K与总β呈现较好的正相关性;箱形图法分析发现^(40)K与总β存在异常值现象;天然水中^(40)K与总β应同时分析与评价以求获得更加准确的测量数据。The relation between ^(40)K and grossβin natural water were described systematically for the first time based on the typical radioactive data results of local groundwater and natural water in other parts of the world and auxiliary data analysis by SPSS.^(40)K was often the main contributor of grossβin natural water.The correlation between ^(40)K and grossβin natural water was statistically significant(P<0.05),even apparently statistically significant(P<0.01)in most cases.There was well positive correlation between ^(40)K and grossβand abnormal value phenomena of ^(40)K and grossβwere found by Box-plot method analysis.^(40)K and grossβin natural waters should be analyzed and evaluated simultaneously to obtain more accurate measured data.
