Abstract
Radium isotopes were measured in groundwater near a radioactive storag e facility which contained pasty residues from monazite and industrial processing sealed in concrete reservoirs. The concentration of radium isotopes in the water was slightly higher than found in the normal dr inking water. The measured Ra-228 to Ra-226 ratio in the groundwater i s not compatible with calculations of radium isotopes ingrow and decay in cake II for different elapsed times, leaving mesothorium cake as t he most likely source of contamination.
