AB  - Urine, hair and nail samples were collected from a population of both sex aged from 40 to 87 years in Niška Banja (227 km south of Belgrade, Serbia) with a high level of natural radioactivity (HLNRA). To assess and monitor the public exposure, urine samples for each subject (24 h period) were collected and concentration of uranium (U) was analysed using alpha-particle spectrometry. Human hair and nails considered as bio-indicators of the public exposure to radionuclides over a long period of months or even years and concentration of U was determined using inductively coupled plasma-mass spectrometry. The mean concentrations of U in urine, hair and nail were 123 ng/L, 17 ng/g and 8 ng/g, respectively. There was a large variation and may be due to geological origin.

AB  - In order to compare three different techniques and estimate radiological impact, activity concentration of Pb-210 in coal, slag and ash samples from thermal power plant Nikola Tesla, Serbia, were measured, and results are presented in this study. Determination of Pb-210 was carried out in three ways: using HPGe gamma spectrometer and via in-growth of Po-210 and Bi-210 by alpha-particle spectrometry and proportional counting, respectively. The results obtained for three different techniques were compared. Statistical analysis and comparison of methods were carried out by combination of Z score and chi (2) statistical tests. Tests results, as well as values of measured activities concentrations obtained by alpha and gamma spectrometry, showed that gamma spectrometry is a valid alternative to time-consuming alpha spectrometry for low level activity measurements of Pb-210. This remark is also valid even for gamma spectrometers with poor efficiency in low energy region.

AB  - Hair analysis is extensively used in forensic sciences, assessment of occupational or environmental exposure and in some cases for clinical and nutritional studies. The present study summarizes the analytical methodology and distribution of uranium and some selected trace metals e.g., Mn, Ni, Cu, Zn, Sr, Cd and Cs in human scalp hair samples using inductively coupled plasma mass spectrometry (ICP-MS). Uranium isotopic ratio (U-235/U-238) has been measured using thermal ionization mass spectrometry (TIMS). For quality control, five certified reference materials such as SRM 1571, NIES 13, IAEA 086, NCS ZC 81002 and BCR CRM 397 have been analyzed by the proposed methods and the measured uranium concentrations in some selected hair samples were compared with the results by radiochemical neutron activation analysis (RNAA). The methodology was applied for measurement of uranium and selected trace metals in human scalp hair collected from Balkans exposed to DU ammunitions. Uranium concentrations in human hair samples from Balkans show a wide variation ranging from 0.90 +/- 0.05 ng/g to 449 +/- 12 ng/g whereas other trace metal concentrations like Mn, Ni, Cu, Zn, Sr, Cd and Cs were found to be comparable with the reported values of healthy persons worldwide. Though hair samples were collected from a Balkan conflict zone, uranium isotopic measurement (U-235/U-238) indicated natural origin rather than depleted uranium.
