Series Description: This report details experiments investigating the removal of cerium-144, yttrium-91, and iodine-131 from tap water solutions under various mixing and pH conditions. The report describes the set-up, execution, and results of the experiments. The investigators found that rapid mixing, long periods of settling, and high pH levels increased the removal of the radioisotopes from the solutions and facilitated the formation of other compounds containing these radioisotopes. Attached tables provide experimental results with radioactivity expressed in counts per minute per milliliter.
