The Impact

In this paper, the impact of increased levels of uranium and radium in soil on the levels of activity and radiation-hygienic validity of animal products of ruminants was investigated.Region around Livno town is placed on coal layer with the in creased levels of uranium and radium compared with other coals used in Bosnia and Herzegovina. As a result of mixing between coal matrix and soil, in creased value of average absorbed dose rate at 1 m above the ground (144 nGy h-1) was measured. The highest average value of 238U and 226Ra in the samples of animal products of ruminants was measured in the samples of sheep cheese (0.070 Bq kg-1 for 238U and 0.207 Bq kg-1 for 226Ra). The levels of these two radionuclides in the rest of animal product of ruminants were aproximatelly similar and ranged 0.016–0.046 Bq kg-1 for 238U and 0.028–0.080 Bq kg-1 for 226Ra. Levels of 40K were in the range of average values for animal products (31.2–86.4 Bq kg-1). Calculated annual effective dose by ingestion of the animal products of ruminants were approximatelly 0.064 mSv with the highest dose contribution of 40K (96.4%). On the base of obtained results, animal products of ruminants produced in observed region, can be considered as valid for human consumption from radiation-hygienic aspect.

All individual living beings on the earth are exposed continuously to the radiations coming from terrestrial and extraterrestrial sources and also from their own bodies. The indoor and outdoor ambient gamma radiations are measured in and around Nuggihalli- Holenarasipura schist belts of Hassan district in Karnataka state. The measurements are carried out using the environment radiation dosimeter UR 705 which is a portable detector. Absorbed dose rate and annual effective dose rate are estimated by measuring the exposure rate. The total annual effective dose calculated from both indoor and outdoor varies from 0.68 to1.62 mSv.y-1 with an average value of 1.16 mSv.y-1. The calculated indoor and outdoor annual effective doses are found to be higher than the world average.

Abstract Natural background gamma radiation was measured along the main roads in the eastern, western and southern regions of Thailand using a car-borne survey system with a 3-in × 3-in NaI (Tl) scintillation spectrometer. The system was able to quickly survey a large area and obtain outdoor absorbed dose rate in air from a gamma ray pulse height distribution. A total of 19 219 data of the outdoor absorbed dose rate in air were collected. The average outdoor absorbed dose rate in air in the eastern, western and southern regions were found to be 8–127, 16–119 and 16–141 nGy h -1 , respectively. The highest outdoor absorbed dose rate in air was detected in the southern region of Thailand. The corresponding average outdoor annual effective dose to the public ranged from 11.7 to 80.8 μSv.

The aim of the article is to assess the level and directions of changes in the subjective structures of animal products processing in the food industry in Poland in 2004 -2015. Considerations were started from the comparison of changes in the subjective structures of the food industry in Poland and the European Union. In the following, changes in the share of individual groups of enterprises were presented, both in the total number of entities, average employment, and in the value of sold production, and the impact of these changes on labor productivity in the analyzed groups of enterprises. Based on the analysis, it can be concluded that the integration processes with the EU and globalization have had a significant impact on the concentration processes in the animal product industries (investments in modernization and adjustment of production to Community requirements). The process of changes in entity structures in this segment was faster than in the entire food industry and was diversified in the industry. The improvement of work efficiency was the result of more production, with relatively stable employment, but also the increase in the technical equipment of work.

The activity concentrations of natural radionuclides (226Ra, 232Th, and 40K) for a set of 31 agricultural soil samples from the Nile River banks in the area of El-Sebaiya city, Aswan Governorate, Egypt were measured by gamma-spectrometry. The study revealed that the average activity concentrations of natural radionuclides 226Ra, 232Th, and 40K were 23.2 ? 2.8Bq/kg, 21.1 ? 2.8 Bq/kg, and 218.6 ? 3.7 Bq/kg, respectively. The obtained results of the activity concentrations are within the range of values reported for neighbouring areas in Egypt. The values obtained for the hazard indices and the representative level index in all sampling sites were lower than unity, showing that there is no significant risk arising from the exposure to the soil in the studied area. The absorbed dose rate and annual effective dose in air outdoors and indoors were calculated from 226Ra, 232Th, and 40K in soil, the average values being 32.64 nGy/h, 40.06 ?Sv, and 160.25 ?Sv, respectively. The absorbed dose rate at the eastof El-Sebaiya city is higher than that obtained for the west because of higher concentrations of tri-calcium phosphate in the soil. The studied area is not significantly affected by the industrial activities, except for a few isolated spots.

Within the scope of this study, the first evaluations of natural (226Ra, 232Th and 40K) and artificial (137Cs) radio isotope activities of the Arzular-Yitirmez-Dölek (Gümüşhane) mine/alteration site were carried out. Measurements were carried out with Poptop Ortec gamma rays detector on 22 soil samples collected from the field. When the natural 232Th, 226Ra and 40K activities of the area are compared with the weighted world averages, it has been determined that the 40K and 226Ra activities exceed the world averages in most of the sampling points, and the 232Th activities are below the weighted world average except for a few sampling points. It was observed that the artificial 137Cs activities in the field were above the detection limit and exceeded 2 Bq/kg except for a few sampling points. It has been evaluated that the high 137Cs activities in the field may be associated with a human-induced effect, especially the accident at the Chernobyl nuclear power plant. Parameters such as radiological hazard indices, Ra equivalent activity value, absorbed dose rate and annual effective dose rate were also calculated for the field. Considering the results obtained from these parameters, it was concluded that it would be beneficial to study the Arzular-Yitirmez-Dölek mineralization/alteration field in more detail in terms of natural and artificial radioisotope activities.
