Potassium is mildly radioactive because one of its natural isotopes is radioactive: 40K undergoes β- decay with a half-life of t1/2 = 1.248 × 10 9 years. The isotopic abundances for potassium are: 39K 93.258 % (atom percent) stable 40K 0.0117 at % β- decay 41K 6.730 at % stable Calculate the activity (measured in curies or becquerel) of 1 cubic centimeter of KCl.
