Abstract: 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.
