Abstract:
Bauxite Residue (BR) is the main waste generated during the alumina-producing Bayer process. With the aim to utilize BR in the production of traditional ceramics, the potential impact such a use might have on the leaching behaviour and radioactivity levels of the final products was investigated. Leaching behaviour of Cr, Ni and V on calcined BR was studied according to the maximal availability test, NEN 7341. Firing atmosphere, firing temperature and soaking time were the investigated parameters. Results demonstrate that the soluble fraction of Cr is higher for oxidizing atmosphere whereas the soluble fraction of V and Ni increases for inert and reducing atmosphere, respectively. For assessing radioactivity, the activity concentrations of 226Ra, 40K, and 232Th were determined by means of gamma ray spectroscopy. For an excess gamma dose less than 1mSv/a, the maximum quantity of BR that can be introduced replacing the raw materials ranges from 14wt.% up to 100wt.%, depending on the type of product and the extent of use in the dwelling.

Abstract:
In cooperation with the Shanghai Environmental Specimen Bank (SESB) research project and in support of the Shanghai government's comprehensive plan to harness the Suzhou River, we collected water and sediment samples in the every spring season since 1998. The elemental analysis of sediment and water samples was performed by the PIXE technique using the 3 × 2 MeV NEC Tandem accelerator at the Taipei Institute of Physics. The characterization of á and â radioactive levels for water and sediment samples was performed using BH1216, low-background, radioactivity instrument at the Shanghai Institute of Nuclear Research. PIXE results showed that the content of Cl , K , Ca , Cr , Mn , Fe , Zn and Pb in river water gradually decreased with the rising tide. At high tide, their concentrations were minimum, and then once again increased toward the ebb tide. The analysis also demonstrated that the radioactivity of water samples had been gradually decreasing year by year. It was found that the decreasing rate of á radioactivity was a little quicker than that of â radioactivity. Further aspects of environmental data evaluation and assessment are also discussed in detail.

Abstract:
The radiological risk due to the presence of natural and man-made radionuclides in beach sands from several renowned seaside and riverbank public beaches was estimated in this study. The exposure levels to terrestrial radiation of the beaches were determined, as well as hazards due to human use of the analyzed sands in industry and in building constructions. Specific radionuclides concentrations in the sand samples were determined by standard gamma-spectrometry. The corresponding radiation hazards arising due to the use of sand as a building material were estimated by three different radiological hazard indices. The total absorbed gamma dose rate in the air was determined and the corresponding annual effective dose outdoors was estimated. The obtained data are relevant both from human health and environmental monitoring aspects.

Abstract:
A cross-sectional survey was conducted in Yauri LGA, Kebbi State in between April, 2015 and January, 2016 in order to ascertain the level of awareness of inhabitant’s exposure to radioactivity from the mines. Yauri LGA was sampled based on its metropolitan and suburban parts that receives heavy mining activities by stratified random sampling by proportions. An interactive medium was created to sample the opinions of inhabitants around these mines through questionnaire. A total of 150 questionnaire were designed, 30 were accepted by the respondents and 22 were returned with response from the correspondents during the survey and interview to document and assessment awareness of the inhabitants. The study unveiled facts about the inhabitant’s awareness towards the environmental and health effect of indiscriminate mining activities around living places. The results shows that over 70% of the inhabitants within the suburb and metropolis concurred to the potential health consequences in their dwellings as a result of exposure to radioactivity from the mines respectively. These results indicates that the environmental and health discomfort due to indiscriminate mining activities around living places will be more significant in the near future if no immediate efforts are put in place to mimic future malady. The second aspect of this study whose results will be published in the subsequent issue involved collection of soil, water and vegetation samples in order to further assess the level of radioactive elements viz: 226Ra, 232Th and 40K occurrence in the study locality.

Abstract:
Objective. to determine the relationship between polymorphisms of glutathione S-transferase gene family and bronchial hyperreactivity in children living in radioactively contaminated areas. Materials and methods. School age children-residents of radioactively contaminated areas (RCA), without clinical signs of respiratory pathology were examined. Molecular genetic studies were carried out by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) for further analysis. The GSTT1, GSTM1 gene deletion polymorphism was investigated using multiplex PCR. PCR and PCR-RFLP analyses were performed in the study of the GSTP1 gene A313G polymorphism. The ventilation lung capacity was examined by the pneumotachographic method according to the analysis of «the flow–volume» loop. The pharmacologic inhalation test with bronchodilator drug, affecting the β2-adrenergic lung receptors was used to detect the early changes in the ventilation lung capacity – the bronchial hyperreactivity (latent and nonlatent bronchospasm). Results. Molecular genetic studies showed that the GSTM1 gene deletion genotype and the GSTP1 gene A313G polymorphism were found significantly more often in the subgroup of children with bronchial hyperreactivity living in RCA than in children without bronchial hyperreactivity and children of the control group. The frequency of GSTT1 deletion polymorphism did not have a statistically significant difference in all subgroups. Conclusions. The GSTM1 gene deletion polymorphism and the GSTP1 gene A313G genotype may be a risk factor for developing bronchial hyperreactivity in children living under adverse environmental conditions, including radioactively contaminated areas. Key words: children, radioactively contaminated areas, bronchial hyperreactivity, glutathione-S-transferase gene polymorphisms.

Abstract:
After the Fukushima nuclear accident in Japan, a number of practical activities related to public understanding (PU) of radiation risks were implemented inside and outside Fukushima Prefecture. The various noteworthy approaches and strategies behind those practical activities have not been organized and made explicit thus far. In this study, we have organized the noteworthy practical activities related to PU of radiation risks following the Fukushima nuclear accident, and discussed them mainly from the standpoints of communication strategies and approaches. As several examples demonstrate, efforts to contextualize and localize radiation risk in various forms were observed during post-accident recovery in Fukushima, and these efforts were confirmed, through actual experiences, to be an important component of effective PU activities of radiation risks. Community-based or citizen science approaches, such as having affected residents or citizens to measure radioactivity, have contributed to the PU of radiological situations, but some challenges, such as ethical aspects and the handling of uncertainty, have also been revealed. In the era of information and communications technology, a number of citizens, experts, and agencies have made social media a popular platform for disseminating radiation risk messages to the public and have demonstrated that social media can play an important role in providing radiological risk information. The knowledge and lessons learned from the practical activities discussed in this study can be useful in enhancing PU of risks not only radiation but also other stressors such as toxic chemicals, preparing future disasters and supporting risk communication plans during recovery periods after disasters.

Abstract:
The increasingly frequent use of nuclear energy in peacetime, experimental nuclear and thermo-nuclear explosions, as well as accidents in nuclear plants lead to an increased and unequal distribution of radioactive substances in the environment. Mankind is in this way threatened not only by environmental irradiation, but also by consuming contaminated food and water which contain radionuclides whose concentrations are above the level of natural radioactivity. From the aspect of the veterinary profession, the most important task is to organize the protection of domestic animals and their products from radioactive contamination. This work presents the results obtained by measurements of the activity level of 137Cs in products of animal origin and cattle feed, in samples obtained from border crossings in Yugoslavia and partly in Macedonia during the period from 1990 until 1999. Examined import samples were taken from cheese, prok, and corn and the activity level of 137Cs was within the permitted legal levels - less than 1 Bq/kg. However, powdered milk was found to contain an activity level of 137Cs from 1,22-7,27 Bq/kg, and saltwater fish from 1,10-3,30 Bq/kg, so that these products could not be released for sale under the Official Gazette of the FRY, Number 53/91.
