    "abstract": "As a result of nuclear power plant accidents, large areas receive radioactive\ninputs of Cs-137. This cesium accumulates in herbs growing in such territories.\nThe problem is whether the herbs contaminated by radiocesium may be used as a\nraw material for medicine. The answer depends on the amount of Cs-137\ntransfered from the contaminated raw material to the medicine. We have\npresented new results of the transfer of Cs-137 from contaminated Digitalis\ngrandiflora Mill. and Convallaria majalis L. to medicine. We found that the\nextraction of Cs-137 depends strongly on the hydrophilicity of the solvent. For\nexample 96.5%(vol.) ethyl alcohol extracts less Cs-137 (11.6%) than 40%(vol.)\nethyl alcohol or pure water (66.2%). The solubility of the cardiac glycosides\nis inverse to the solubility of cesium, which may be of use in the\ntechnological processes for manufacturing ecologically pure herbal medicine.",
