We determined the iron, zinc, selenium, rubidium, and cesium concentrations in serum and packed blood cells by instrumental neutron activation analysis without chemical separations. Lyophilized samples were irradiated for 12 days at a flux of 10(13) neutrons-cm-2-s-1, mineralized by wet digestion, and measured two times with a high-resolution Ge(Li) detector--for 6 h about a month after the irradiation and for 15 h two or three months after the irradiation, The following values were obtained: 163 +/- 0.43 mg/liter (serum iron), 1025 +/- 136 mg/kg wet wt (packed cells iron), 1¿ +/- 0.20 mg/liter (serum zinc), 11.15 +/- 1.83 mg/kg wet wt (packed cells zinc), 0.13 +/- 0.02 mg/liter (serum selenium), 0.16 +/- 0.03 mg/kg wet wt (packed cells selenium), 0.17 +/- 0.04 mg/liter (serum rubidium), 4.28 +/- 0.98 mg/kg wet wt (packed cells rubidium), 0.74 +/- 0.20 microgram/liter (serum cesium), and 4.82 +/- 2.10 microgram/kg wet wt (packed cells cesium).
我们采用仪器中子活化分析法，在不进行化学分离的情况下测定了血清和红细胞压积中的铁、锌、硒、铷和铯浓度。冻干样本在通量为10(13)中子·厘米-2·秒-1的条件下辐照12天，经湿法消解进行矿化处理，然后用高分辨率锗（锂）探测器测量两次——辐照后约一个月测量6小时，辐照后两到三个月测量15小时，得到以下数值：163±0.43毫克/升（血清铁），1025±136毫克/千克湿重（红细胞压积铁），1±0.20毫克/升（血清锌），11.15±1.83毫克/千克湿重（红细胞压积锌），0.13±0.02毫克/升（血清硒），0.16±0.03毫克/千克湿重（红细胞压积硒），0.17±0.04毫克/升（血清铷），4.28±0.98毫克/千克湿重（红细胞压积铷），0.74±0.20微克/升（血清铯），以及4.82±2.10微克/千克湿重（红细胞压积铯）。
