Keywords:radioactive strontium, calcium carbonate, co-crystallization, degree of decontamination, degree of supersaturation

Radioactive strontium was continuously removed from contaminated fresh water by continuous co-crystalization with calcium carbonate. The degree of the decontamination increased with increasing concentration of the supersaturated calcium carbonate, and was reached more than 99.5%.
