Ordinary hospital meals for adults were simultaneously measured for Na and Cl by neutron activation analysis (NAA). Results obtained are summarized as follows: 1. Daily Na intake was estimated to be 4 to 8 g, corresponding to 11 to 18 g of salt. Daily Cl intake was estimated to be 5 to 9 g, corresponding to 7 to 12 g of salt. Their ratio was 1.6. 2. The higher values of salt intake obtained by conversion from Na intake are attributable to food additives. 3. In rating Na content, which has been reported to affect blood pressure, on the basis of salt intake, attention must be given to the fact that salt content converted from Cl content is rated to be lower than that converted from Na content.
采用中子活化分析法（NAA）同时测定普通成人医院膳食中的钠和氯。所得结果总结如下：1. 每日钠摄入量估计为4至8克，相当于11至18克盐。每日氯摄入量估计为5至9克，相当于7至12克盐。它们的比例为1.6。2. 通过钠摄入量换算得出的较高盐摄入量值归因于食品添加剂。3. 在根据盐摄入量对据报道会影响血压的钠含量进行评级时，必须注意这样一个事实，即由氯含量换算得出的盐含量评级低于由钠含量换算得出的盐含量评级。
