In an Environmental Radioactivity Laboratory, samples from several products are analyzed, in order to determine the amount of radioactive products they contain. A usual method is the gamma activity measurement of these samples, which typically requires the use of High Purity Germanium Detectors (HPGe). GMX (n-type) detectors can be found among this group of detectors. They have a high efficienc...

The investigation of the environmental radioactivity around the radioactive waste disposal site in Gyeongju is being carried out. The radioactivity of I in groundwater and seaweed are to be measured. The analytical method to measure the radioactivity of I in aqueous media was established. This method contains oxidation-reduction reaction, anion-exchange separation and palladium precipitation. T...

Background: Salivary flow rate (SFR), to estimate salivary gland dysfunction and radioactivity in different body fluids, to evaluate its intensity, were determined in thyroid patients after 131-I therapy. Material and Methods: For determination of SFR an innovative sponge test was adopted and the radioactivity in saliva, blood and serum of thyroid patients was determined by NaI (TI) Scintillati...
