FSUsion track estimation of uranium concentrations in liquid homeopathic medicine samples

摘要

The ingestion of excessive amount of uranium in homeopathic medicines can damage human's kidneys by preventing normal elimination of urea and other waste products and can cause renal dysfunction. Quantitative determination of uranium in medicines SU, therefore, very important. FSUsion track technique has been applied for the estimation of uranium concentration in homeopathic medicine samples collected from local market. The technique involved simultaneous irradiation of medicine samples and a standard, in contact with track detectors, with thermal neutrons and counting of the fSUsion tracks produced in the detectors as a reSUlt of (n, f) nuclear reaction. Uranium concentration in the medicine samples varied from (0.003 +/- 0.001) mg L-1 to (0.297 +/- 0.010) mg L-1 with an average value of (0.020 +/- 0.001) mg L-1. The observed concentrations were less than the permSUsible intake level of uranium. So, general public SU at no rSUk while using these medicines for treatment purposes.
