This paper reports the results of radioactivity concentrations and heavy metal content in soil samples collected from non-agricultural areas municipality vicinity North Kosovska Mitrovica, formerly most important mining area Europe. The estimated average activity 226Ra, 232Th, 40K 137Cs are 40.6 ± 19, 48 25.4, 743.2 200.5 81 119 Bq kg−1, respectively. absorbed dose rate air annual effective 78.7 nGy h−1 96.6 μSv, radium equivalent external hazard index were also calculated. High contents Pb,...
In urban areas, forest patches and parks are usually the places where people spend most of their time outdoors. Because poor environmental protection policy insufficient investment in industry energy, Serbia is often ranked among European countries with greatest pollution. recent years, ecological protests have been organized throughout country aim raising awareness resolving issues. The topic has become particularly popular since plans for opening new mining areas western came to fore. This...
Measurements of radon activity concentrations have been conducted in public kindergartens, primary, and secondary schools Kragujevac City. This study represents the first step towards mapping Central Serbia. Passive discriminative radon/thoron detectors (so called UFO) were used for monitoring. The calibration coefficient 0.026 (track/cm 2 )/(Bq m −3 day) was calculated by exposing UFO a Rn chamber monitored RAD7 device. concentration range 27–145 Bq kindergartens 25–86 schools. value...
Some previous studies on radon concentration in dwellings of some areas Kosovo and Metohija have revealed a high average concentration, even though the detectors were exposed for three months only. In order to better design larger study this region, annual measurements 25 houses carried out as pilot study. For each house, CR-39-based passive devices two rooms consecutive six-month periods account seasonal variations concentration. Furthermore, correlate indoor with radium nearby soil improve...
Computer software for calculation of the sensitivity a CR-39 detector closed in diffusion chamber to radon is described this work. The consists two programs, both written standard Fortran 90 programming language. physical background and numerical example are given. Presented intended numerous researches measurement community. Previously published computer programs TRACK_TEST.F90 TRACK_VISION.F90 [D. Nikezic K. N. Yu, Comput. Phys. Commun.174, 160 (2006); D. Commun.178, 591 (2008)] used here...
Measuring of radon and thoron progeny concentrations in air, based on air filtration, was analysed order to assess the reliability method. Changes activities filter during after sampling were investigated. Simulation experiments performed involving realistic measuring parameters. The sensitivity results (radon air) variations alpha counting three five intervals studied. concentration (218)Po showed up be most sensitive these changes, as expected because its short half-life. well-known method...
The computer programs TRACK_TEST and TRACK_VISION were previously developed to model profiles optical appearances of tracks in solid-state nuclear track detectors. based on a development that involved the bulk etch rate Vb Vt or V function (i.e., Vt/Vb). present work reported our update modify these two programs. In revised TRACK_TEST, new functions added enabled. Sample results for CR-39 detector obtained using three original compared. Discrepancies within ~10% <14% incident...
