AB  - The probabilities of locating peaks with a high relative peak-area uncertainty were determined empirically with nine types of peak-location software used in laboratories engaged in gamma-ray spectrometry measurements. It was found that it is not possible to locate peaks with a probability of 0.95, when they have a relative peak-area uncertainty in excess of 50%. Locating peaks at these relatively high peak-area uncertainties with a probability greater than 0.95 is only possible in the library-driven mode, where the peak positions are supposed a-priori. The deficiencies of the library-driven mode and the possibilities to improve the probabilities of locating peaks are briefly discussed. © 2019 Elsevier Ltd

AB  - A method is presented for calculating the expected number of counts in peaks that have a large relative peak area uncertainty and appear in measured gamma-ray spectra. The method was applied to calculations of the correction factors for peaks occurring in the spectra of radon daughters. It was shown that the factors used for correcting the calculated peak areas to their expected values decrease with an increasing relative peak-area uncertainty. The accuracy of taking the systematic influence inducing the correction factors into account is given by the dispersion of the correction factors corresponding to specific peaks. It was shown that the highest accuracy is obtained in the peak analyses with the GammaVision and Gamma-W software.

AB  - It is well-known that radon is the second important human carcinogen for lung cancer, after smoking. The major sources of indoor radon concentrations are soil and building material. Under certain conditions, a dose received from the inhalation of radon and its progenies can be higher than a dose received from the external exposure due to radium concentration in building materials. In this contribution, the results of the radon and thoron exhalation rate measurement from 9 commonly used building materials are reported.

AB  - The coincidence summing effect plays an important role in HPGe spectrometry, especially at low source-detector distances, due to a large solid angle; therefore, the calculation of correction factors is necessary. The aim of the research described in this paper was to compare values of correction factors for a 22Na point source obtained using the GESPECOR software package (Monte-Carlo method) and experimentally obtained values. Measurements were performed using a semiconductor HPGe spectrometer and the point source axially positioned at nine different distances from the detector end-cap. For the purpose of determining correction factors, a system of equations was formed, which, besides nuclear data as the input parameters, uses the experimentally obtained values of the total count in the entire spectrum, as well as the counts in the full energy peaks. The system of equations was solved for each particular case and correction factors were determined. By comparing the results obtained using the experimental and Monte-Carlo method, it was found that the correction factors for the 22Na point source have discrepancies less than 3%. The significance of these discrepancies was also verified from a statistical point of view using a Student's t-test. © 2019 RAD Association. All rights reserved.

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  - The half-life of Ne-19 was measured using a real-time digital multiparametric acquisition system, providing an accurate time stamp and relevant information on the detector signals for each decay event. An exhaustive offline analysis of the data gave unique access to experimental effects potentially biasing the measurement. After establishing the influence factors impacting the measurement such as after-pulses, pile-up, gain, and baseline fluctuations, their effects were accurately estimated and the event selection optimized. The resulting half-life, 17.2569 +/- 0.0019((stat)) +/- 0.0009((syst)) s, is the most precise up to now for Ne-19. It is found to be in agreement with two recent precise measurements and not consistent with the most recent one [L.J. Broussard et al., Phys. Rev. Lett. 112, 212301 (2014)] by 3.0 standard deviations. The full potential of the technique for nuclei with half-lives of a few seconds is discussed.

AB  - Laundry detergents are chemicals widely used in everyday life, and in numerous industry branches. In order to perceive the radiological aspect of environmental pollution by wastewater, the analysis of laundry detergents available on the Serbian market was undertaken. Laundry detergent samples were measured by means of gamma spectrometry and the results are presented in this paper. Analysis of the obtained activity concentrations showed that laundry detergents in Serbia mostly fulfill the international recommendation and requirements regarding the phosphate content. Besides that, the content of the detected radionuclides in laundry detergent samples indicates the minor radiological risk to the environment via wastewaters.

AB  - Gamma ray spectrometry is an analytical method that allows the identification and
quantification of gamma emitting radioisotopes in soil and other environmental
samples. 31 samples of soil were collected from different location in the territory of
Aleksandrovac municipality. All soil samples were dried, milled and sealed in two
different geometries (500 ml Marinelli beaker and 125 ml cylindrical boxes) and stored
for six weeks in order to reach radioactive equilibrium between 226Ra and its
descendants. All samples stored in cylindrical boxes were measured by means of two
coaxial semiconductor HPGe detectors with different characteristics, while samples
stored in Marinelli beakers were measured only by means of one coaxial semiconductor
HPGe detector. The activity concentrations of radionuclides 40K, 137Cs, 235U, 226Ra, 238U
and 228Ac in all soil samples were determined. Variations in specific activities
determination for different geometries measured using one of the detectors, as well as
for cylindrical box geometry measured using both detectors, are presented in this
paper. The causes of these variations are analyzed.

AB  - У гама спектрометрији се често сусрећемо са ефектом коинцидентног
сумирања, а самим тим постоји потреба за одређивањем корекционих фактора.
Циљ истраживања описаног у овом раду је поређење вредности корекционих
фактора за тачкасти извор
88Y добијених помоћу софтверског пакета
GESPECOR (Монте Карло методом) и експериментално добијених вредности.
Мерења су обављена помоћу полупроводничког HPGe спектрометра, при чему је
тачкасти извор био позициониран на аксијалној оси детектора на девет
различитих растојања од капе детектора. Формиран је систем једначина, који
осим нуклеарних података, као улазне параметре користи и експериментално
добијене вредности тоталног одброја у целом спектру, као и одброја испод
фотопикова. На основу решавања система једначина одређени су корекциони
фактори за коинцидентно сумирање. Упоређивањем резултата, утврђено је да
се вредности корекционих фактора добијених помоћу ове две методе разликују до
3 %.
AB  - In gamma ray spectrometry often deals with coincidence summing effect, and therefore
calculation of correction factors is necessary. Coincidence summing effect play an
important role in HPGe spectrometry at low source-detector distances, due to the large
solid angle subtended by the detector at the source. The aim of research described in
this paper was to compare values of correction factors for point source 88Y obtained
using the software package GESPECOR (Monte-Carlo method) and experimentally
obtained values. Measurements were performed using a semiconductor HPGe
spectrometer, wherein point source was axially located on detector at nine different
distances. The system of equations was formed whereas net areas in full energy peaks
as well as in entire spectrum were used as input data. The system was solved and
correction factors for point source 88Y were determined. By comparing the obtained
values, it was found that correction factors obtained by these two methods have
discrepancy less than 3 %.
