摘　　要：简要说明了一种盐田卤水中钾的放射性测定方法。该方法采用两个探头，其中一个探头测量卤水中的计数，另一个探头测量本底计数。取两个探头计数之差来计算卤水中钾的含量。用该方法在实验室试验结果表明，可较好地克服本底计数波动的干扰．提高测钾精度。The technique for the radiatlvity determination of potassium in salt-bond brine was briefly described. In this method,two probes were employed to record brine count and base count, respectively, and the potassium concentration in brine was determined by the difference of the two counts corresponding to the two probes. Experimental data showed that such a technique could reduce the adverse effect caused by the random fluctuating of base count,and therefore improve the procession of potassium determination.
