【摘要】 将放化分离与单道Ｙ谱仪测量结合，建立了一种适用于海水样品中￣（６０）Ｃｏ分析的方法。实验结果表明，本方法在分析１０Ｌ海水样品时，钴的化学回收率为９２．６％；用国产ＦＴ－６０３＃型Ｙ探头组装的单道Ｙ谱仪对￣（６０）Ｃｏ进行１００ｍｉｎ计数，得到本方法的探测下限为０．０６Ｂｑ／Ｌ。更多还原

【Abstract】 A radiochemical method conbined with Y-raysspectrometric measurement was de-veloped for ￣(60)Co determination in seawater samples.Co chemical recovery of 92.6%. The de-tection limit was found to be 0.06Bq/L when a single-channel Y-raysspectrometer composedof FT- 603 well type detector was used for measurement with counting time of l00 min.更多还原
