Preliminary investigations on reducing the high radiation risk level of TENORM scale waste from petroleum industry

摘要

The main objective of this study is directed to remove Ra-226, Ra-228 radionuclides from TENORM scale waste without seriously degradation the physicochemical characteristics of soils or generating waste. It was found that 82, 87% removal of total radioactivity using successive washing by commercial and TX-100 solutions, respectively, after seven cycles. Some radiation risk before and after treatment with surfactants were determined. It is a promising and efficient as well as economic process. Our results from this task could provide a useful information for defining the establishing and operating on a pilotscale plant for efficient and economic TENORM treatment.
