摘要
按照《牛奶中碘-131的分析方法》(GB/T 14674-93),对2011~2016年间杭州乔司奶场牛奶中I-131放射性进行检测分析,结果表明,牛奶中I-131的化学回收率为43.2%~59.5%,活度浓度范围为1.3~2.7 m Bq/L,小于仪器探测限且无异常值,属于正常饮用水平。
Based on Analytical Method for 131 I in Milk(GB/T 14674-93), the I-131 radiation of the milk of Hangzhou Qiaosi Dairy Farm was analyzed from 2011 to 2016. The results show the chemical recovery of I-131 in milk is between 43.2% to 59.5% and the activity concentrations are between 1.3 m Bq/L to 2.7 m Bq/L, which are lower than the limitation of the detector and is within the normal range for drinking.
