AB  - Gamaspektrometrija je jedna od najčešće korišćenih metoda za kvalitativno i
kvantitativno određivanje sadržaja radionuklida u zemljištu i drugim uzorcima iz
životne sredine. Meren je 31 uzorak zemljišta sa teritorije opštine Aleksandrovac, pri
čemu su za svaki uzorak korišćene dve različite geometrije (cilindrična kutijica i
marineli posuda). Određene su specifične aktivnosti radioizotopa uranovog i torijumovog niza, kao i 235U, 40K i 137Cs. Uzorci zemlje u geometriji cilindrične kutijice mereni
sa na dva HPGe detektora različitih efikasnosti i karakteristika, dok su uzorci u
marineli posudi mereni samo na jednom HPGe detektoru. U radu su prikazani rezultati
poređenja specifičnih aktivnosti istih radionuklida dobijenih merenjem uzoraka u
različitim geometrijama na istom HPGe detektoru kao i uzoraka u geometriji
cilindrične kutijice merenih na različitim detektorima. Analizirani su uzroci nastalih
varijacija.
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  - With an increase in the awareness of the need to save energy, residents tend to live in dwellings with increasingly tight windows and doors, thus reducing the ventilation rate of indoor air which leads to an increased accumulation of radon indoors. Having in mind that a dose from an exposure to inhaled radon and its progenies can be higher than a dose received from radium in building materials, it is suggested that radon exhalation measurements should receive due attention. In this contribution, the authors compare results gathered using a few methods for radon exhalation measurement and discuss its merits and demerits.
