AB  - Geopolymers are a class of alkali activated binders, and present a viable alternative to Portland cement. Utilization of geopolymers is a way to reduce greenhouse gas emissions and utilize secondary materials.Geopolymers are becoming a material of choice in radioactive waste conditioning, for grouting and encapsulation. Binder set times are a key parameter in determining the workability of grouts, mortars and concrete. While studying the effects of ionizing radiation on geopolymer set times, we were constrained by the configuration of the irradiation device and field, so we developed a modified Vicat apparatus, sample case/phantom, and temperature/humidity monitor. The modified procedure has allowed for a better temporal resolution of the measurements, with continuous monitoring of the experimental conditions. Fly-ash geopolymer set times under Co-60 gamma radiation are presented.

AB  - The activity concentrations of 226Ra, 232Th and 40K were determined in 43 soil samples collected from 0 to 10 cm and 10 to 50 cm depths of Niška Banja region, Serbia, using a low background gamma spectroscopy with 3″ × 3″ NaI(Tl) scintillation detector. The mean absorbed dose rate of 0–10 cm and 10–50 cm depth soil were 66.1 and 60.4 nGy/h, respectively which was close to UNSCEAR worldwide value. The radium equivalent and annual effective dose effect were lower than the permissible level. Therefore, there is no significant radiological risk from the soil to residents living in this region. © 2023, Akadémiai Kiadó, Budapest, Hungary.

AB  - The paper deals with the analysis of the annual indoor radon concentrations variations due to different geological parameters of Sjenica community, Western Serbia. The measured 222Rn concentrations were ranging from 10 to 1130 Bq/m3. In 14% of the buildings, the radon action level of 300 Bq/m3 is exceeded, indicating that Sjenica community could be characterized as a radon priority area. Each of 35 measuring location was georeferenced and corresponding lithostratigraphic units and geological period was assigned. Data were analyzed using the multiple linear regression (MLR) method and two predictive models were developed. The MLR model generated by the geological periods explained 17% of the radon variability while, the better one, was the lithostratigraphic MLR model, which explained 52% of the radon variability. Analysis has shown that lithostratigraphic units are important parameters in the prediction of radon levels. © 2019 Carpathian Journal of Earth and Environmental Sciences.

The experience with four different methods of the exhalation measurement, established in our laboratory for the purpose of the intercomparison is reported.
