Dutch distribution zones of stable iodine tablets based on atmospheric dispersion modelling of accidental releases from nuclear power plants

Due to the fact that the potential threat to the health to the public living near nuclear power plants is largely determined by the level of air pollution by radionuclides, identification of the dispersion conditions of pollutants in the atmospheric boundary layer is of great importance in the development of engineering protection means for nuclear facilities. In turn, the engineering protection of nuclear power plants provides for the development of automated radiation monitoring systems and their main components, i. e. atmospheric boundary layer status monitoring systems. When analyzing and predicting the radiation situation in the vicinity of nuclear power plants, the determination of atmospheric dispersion variability parameters over time is essential. This research is aimed at assessing interannual and intra-annual variability of atmospheric dispersion parameters in the Belorussian nuclear power plant siting region based on the atmospheric boundary layer monitoring data. This study has revealed the relative interannual stability of the main average annual atmospheric dispersion characteristics throughout the observation period in 2015-2019. At the same time, the average seasonal values of the atmospheric boundary layer dispersion parameters are characterized by significant fluctuations thereof over the annual course. The feasibility of such monitoring for other potentially hazardous industrial facilities, such as thermal power plants and chemical plants, is also noted.

Abstract Purpose：The aim of this study was to clarify the characteristics and the awareness of nuclear prevention measures including prophylactic stable iodine (SI) of guardians of 0- to 6-year-old children living in the urgent protective action planning zone (UPZ) of the Genkai Nuclear Power Plant (GNPP), Japan. Methods：Of these 1172 guardians, 973 responded that they wished to receive pre-distribution of stable iodine (PDSI) and 199 did not wish to receive PDSI. Results: Logistic regression analysis showed that the following items were independently associated with guardians who wished to receive PDSI for their children: thinking that pregnant women should take prophylactic SI (odds ratio [OR]=6.57, 95% confidence interval [CI]: 4.62–9.35; p<0.01); wishing to participate in a lecture about the health effects of radiation exposure (OR=1.99, 95%CI: 1.40–2.82; p<0.01); thinking that SI can prevent exposure from all radionuclides (OR=1.93, 95%CI: 1.24–2.99; p<0.01); awareness of SI before the study (OR=1.91, 95%CI: 1.35–3.00; p<0.01); and anxiety about prophylactic SI for their children (OR=0.33, 95%CI: 0.20–0.55; p<0.01). The GNPP was one of the nuclear power plants in Japan that resumed operations after the Fukushima Dai-ichi Nuclear Power Plant accident in 2011. Conclusion: These results suggest that some residents have incomplete knowledge about nuclear prevention, including SI. Therefore, it is essential to educate residents and communicate the health risks of radiation exposure with residents living around nuclear power plants. Furthermore, it is important to train specialists to educate and communicate with residents to prepare for a nuclear accident.
