Using 222Rn as a naturally occurring tracer to estimate NAPL contamination in an aquifer
Autor: Dong-Chan Koh, Jae Ha Yang, Kil Yong Lee, Yoon Yeol Yoon, Soo Young Cho, Kang-Kun Lee
Publikováno v: Applied Radiation and Isotopes. 81:233-237
The naturally occurring radioisotope (222)Rn was used as a partitioning tracer to evaluate the presence and amount of a non-aqueous phase liquid (NAPL) in an aquifer. The batch experiment results of a diesel contaminated soil showed that the emanatio
