| 中文摘要 |
| 本文报道辽宁省18种不同环境样品中226Ra与238U比值的测定。结果表明,粮食、蔬菜类食品的比值范围在2.6-9.7,均值为4.8;饮用水的比值范围在0.36-0.45,均值为0.40.土壤、矿石和磷肥等以矿物质为主的样品的比值范围为0.86-1.10,均值为0.98.讨论了在环境放射性监测方面,样品中226Ra与238U比值应用的现状和前景。 |
| 英文摘要 |
| This paper describes the ratio of226 Ra to 238U in 19 kinds of environmental samples in Liaoning Province. The determined results showed that the ratios of 226Ra to 238U in grain and vegetable samples were between 2.6-9.7, mean value was 4.8, those in drinking water between 0.36-0.45, mean value 0.40, and those in soil, ore and phosphate fertilizer were between 0.86-1.10, mean value 0.98. The authors presented a discussion on application of the ratios in environmental monitoring. |
