Investigation on Sorption and Migration of ~(90)Sr、~(137)Cs in Solidified Cement

Both batch and column test are used to investigate the sorption and migration behaviors of 90 Sr, 137 Cs on solidified cement with aluminum rich alkai slag and 525 # cement. The results show that the sorption ratio of solidified cement is ten times of 525 # cement. pH of drip washing solution affect the function of sorption and migration. The aluminum rich alkai slag cement is much better than 525 # cement in preventing migration of radioactive 90 Sr and 137 Cs.
