Summary: The study conducted indoor radon level detection with a RAD7 radon detector in 21 bedrooms of households in Weifang city, and calculated the annual effective radiation dose for ordinary residents. Significant differences in radon levels were found between different floors. It is suggested that more attention should be paid to Rn-220 in future research in Weifang city.

Summary: The results of scientific work presented in the WHO report indicate that exposure to radon increases the risk of lung cancer in humans, particularly in children. Measurement evaluations in nurseries revealed similar variability in radon concentration and showed that higher values were influenced by low wind speeds. The study also found that public awareness of radioactivity is generally low. The results of the effective dose levels can be used to optimize future radon testing in various building purposes.

Summary: This study investigated the potential harmful radon gas emanation in Self-Compacting Concrete (SCC) with higher dust material. Different SCCs with various mineral additives were placed in closed glass environments for measurement of radon activity concentrations (ARACs) using CR-39 detectors. The results showed that ARAC values increased with the addition of fly ash (FA) and decreased with the addition of silica fume (SF). The highest annual effective equivalent dose (AEED) was found in SCC with 20% FA. The study confirmed the hypotheses based on mineral additive type and rate.

Summary: Seasonal monitoring of Rn-222 and Rn-220 and their progenies was conducted in 150 dwellings of district Gurugram, Haryana, India, using Pin-holes dosimeter and deposition-based sensors. Annual indoor mean concentrations of Rn-222, Rn-220, radon progeny, and thoron progeny were found within the ranges of 8.1-76.2 Bqm(-3), 10.2-86.2 Bqm(-3), 1.2-32.5 Bqm(-3), and 0.2-14.1 Bqm(-3), respectively. Winter season and modern dwellings showed the highest levels. Measured radionuclides concentrations were used to calculate the total annual effective dose.

Summary: This study investigated the spatial distribution of alpha particle tracks produced by radon and its progeny in radon diffusion chambers. The nonuniform distribution of alpha particle tracks on detector surface was found to be influenced by chamber dimensions and critical angle of particle detection. Experimental results were compared with analytical predictions and software based on Monte Carlo method with some expressions significantly underestimating the results.

Summary: This article presents the results of radiochemical events/processes that occur when water is exposed to ionising radiation of charged particles (beta and alpha-particles). The idea of cogeneration becomes even more lucrative if we consider that hydrogen energy generation is clean (also known as green energy) because of its insignificant contribution to environmental pollution. These results supplement the fluctuation in effective dose theory/hypothesis of a previous study on time-dependent variations in the radiological health impact of an interim SNFS facility presented in 2021 (Leotlela, 2021).

Summary: This work explores the possibility of using a polymer composite to protect against neutron radiation in space conditions. The study shows that the proposed polymer composite has high structural properties necessary for use in space. Monte Carlo simulation is used to evaluate the neutron radiation passage through the material. The results demonstrate that the protective layer made of the polymer composite is thinner and more suitable for spacecraft, which is crucial due to limited space on board.

Summary: This study investigated the effects of Neodymium (III) nitrate hexahydrate and lanthanum nitrate hexahydrate on the structural and radiation shielding properties of zircon mineral, and a new La/Nb-doped ZrO2 nanocomposite was fabricated. Experimental techniques such as energy-dispersive X-ray, scanning electron microscope, transmission electron microscopy, and X-ray diffraction pattern were used to analyze the structure and composition of the fabricated nanocomposites. Monte Carlo simulation was employed to evaluate the gamma-ray shielding properties. The results showed that the fabricated composites had good shielding characteristics, with a shielding capacity of 30-50% compared to pure lead in the intermediate energy range of 0.244-2.506 MeV.
