Barium-137m
웹Why is barium 137 Safe? This Cs-137/Ba-137m Isotope Generator is used to demonstrate the properties of radioactive decay. … Approximately 30 minutes after elution, the residual activity of the Ba-137m sample has decayed to less than one thousandth of its initial activity, making it safe for disposal. http://electron6.phys.utk.edu/phys250/Laboratories/radioactive_halflife_of_ba.htm
