When examining the genes of children such as residents in the vicinity who were exposed to radiation in the accident at the Chernobyl nuclear power plant in the former Soviet Union, the research results that the effects of parental exposure were not found in the genes of children were found in Japan and Announced by international research groups such as the United States.
After the Chernobyl accident in 1986, international research groups such as Japan, the United States, Ukraine, and Russia have examined the genes of 130 children who were involved in decontamination work and residents in the vicinity with a radius of 70 km. Published in the magazine "Science".
According to it, the children were born between the year following the accident and 2002, and
the radiation dose received by the father averaged 365 millisieverts, up to 4080 millisieverts, and the mother received an average of 19 millisieverts, up to 19 millisieverts. It was 550 millisieverts, but the rate of mutations in genes such as germ cells of children was the same as when the parents were exposed to a large amount of radiation.
The research group says that the genes of children are not affected by exposure, and the health effects inherited from parents are expected to be extremely small.
Nori Nakamura, an adviser to the Radiation Effects Research Foundation, who participated in the study, said, "Analysis of more than 100 people has shown that the genetic effects of parental exposure on children are limited. Continued analysis is necessary, but Fukushima I would like people to see this as data that will help alleviate their anxieties to some extent. "
