During Chernobyl accident a large amount of radionuclides were released into atmosphere and added to atmospheric nuclide inventory from weapons tests. In early May of 1986 in South Korea, radioactivities such as 1-131 and Cs-137 were detected in surface air and rain water. That indicated that Chernobyl debris spreaded to far eastern Asia. In the present time, the long-lived radionuclides have b...

Organisms differ in their susceptibility to ionizing radiation 27 although the ecological basis for such differences remain poorly 28 understood. We hypothesized that ecological characteristics such as body 29 size, diet, migration and pigments of plumage would predict the impact of 30 radiation on abundance through effects on relative food consumption rates, 31 free radicals and antioxidants. ...

On 26 April 2016, thirty years will have elapsed since the occurrence of the Chernobyl accident, which has so far been the most severe in the history of the nuclear reactor industry. Numerous epidemiological studies were conducted to evaluate the possible health consequences of the accident. Since the credibility of the association between the radiation exposure and health outcome is highly dep...

Background: Thyroid cancer incidence of individual dose groups in Fukushima residents exposed at ≤18 years age demonstrated a linear response to thyroid estimated the United Nations Scientific Committee on effects Atomic Radiation (UNSCEAR) 2020/2021. Increased childhood was found come dominantly from radiation exposure nuclear accident. The UNSCEAR 2020/2021 concluded that apparent excess canc...

This study assesses parameters of thyroid function in persons who resided in Ukraine, Belarus, and southern Russia and exposed at 0 to 16 years of age to radioiodine contamination from the Chernobyl accident. Six to eight years after the accident a group of 300 young people who had immigrated to Israel were interviewed, underwent physical and ultrasound thyroid examination, and had their serum ...

We analyzed mid- to long-term 137Cs wash-off from the catchments contaminated due Chernobyl accident in 1986 and Fukushima Dai-ichi Nuclear Power Plant 2011. A semi-empirical diffusional model for radionuclide is proposed enable estimation of dissolved particulate ratios catchments; differences characteristics these two regions are explained their trends predicted. The based on premise that cat...

After the Tokyo Electric Power Company Fukushima Daiichi nuclear power plant accident, cancer risk from low-dose radiation exposure has been deeply concerning. The linear no-threshold model is applied for the purpose of radiation protection, but it is a model based on the concept that ionizing radiation induces stochastic oncogenic alterations in the target cells. As the elucidation of the mech...
