| 中文摘要: |
| 本文报道了30种常用食品210Pb含量, 它们是在样品中210Pb～210Po接近放射性平衡后, 用银片自沉积法测定210Po, 计算出210Pb含量。粮食、蔬菜和肉类的210Pb平均浓度分剐为0.14, 15.08和1.26×10-14Ci/g。 |
| 英文摘要: |
| The contents of 210Pb in 30 kinds of commonly used foods are given in the paper, After the radioactive equilibrium between 210Pb and 210Po was nearly established in samples, the concentration of 210Pb was determined by the method of spontaneous deposition on silver disc, The contents of 210Pb then were calculated from that of 210Po, The average
contents of 210Pb in corn, vegetable and meat were 0.14, 15.08 and 1.26 × 10-14Ci/g respectively, |
