A comparative study is presented on decontamination of the solutions containing226Ra(II), by applying coprecipitation of Ba(Ra)SO4 followed by flotation and selective adsorption on active carbon. The comparative study revealed the performances of separation
by coprecipitation-flotation and the possibility of applying the selective adsorption on active carbon. Both methods ensure
the decreasing of226Ra(II) concentration under the allowed limits, recommended by International Standards.
