Impact of the production process of drugs on cesium-137 transition into liquid medicinal forms

Degrees of 137Cs transformation from medicinal plants to the solution depending on the technology of medicinal form (MF) preparation are determined. Analysis has shown that the part of a radionuclide transforming into water MF (infusions and decoctions) is considerably higher than in alcohol MF (infusions and extracts) and it constitutes in the average 70±10%. The degree of 137Cs transformation to infusions and extracts prepared on the alcohol base equals 25±5%. Good coincidence of specific activity of the initial sample with the sum of specific activities of liquid MF and dry sample residues was observed
