Abstract: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.
Keywords:radium-226  uranium-238  environmental monitoring
