METHOD FOR RADIOMETRICALLY CHARACTERIZING THE SPELEOTHERAPEUTIC FACTORS IN SALT MINES

摘要

The invention relates to a method for radiometrically characterizing the speleotherapeutic factors in a salt mine, with a view to employing the natural saline underground environment factors having healing properties for the prophylaxis, treatment and recovery of patients with some pathologies and in the balneary and climatic tourism. The method claimed by the invention consists in measuring the volume activity of the atmospheric radon, the radon concentration range being of 7+ 0.39...95 + 4.76 Bq/m, in the measurement and spectrometric analysis in unprocessed salt samples, with the mass of 100 g and measuring time of 86400 s, to result in total activities of 20...25 Bq/kg for the white salt and 50...65 Bq/kg, respectively, for the black salt, in measuring the overall alpha-beta volume activity in salt samples with the mass of 1..2 g, the radioactivity concentrations ranges being of 2...8 Bq/kg for radiation and of 10...15 Bq/kg for radiation, respectively, and measuring the natural radiation background in the salt mine to result in a natural radiation background given by the relation (0.002...0.006) S /h (2...6 nSv).
