| Outline of Final Research Achievements |
To clarify whether low-dose radiation exposure caused by the accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP) in March 2011 has had genetic effects on wild plants and animals, we examined the mutation rate of germ line and the DNA oxidative damage in needles of Pinus densiflora, to which reference plants of ICRP can be applied. Allele frequencies of radiosensitivity-related genes were also examined in Apodemus speciosus, to which reference animals of ICRP can be applied. No statistical difference was detected between the high-dose area and the control area for any of the measurements. Although our results do not eliminate the possibility that some effects could be detected by analyzing a larger number of samples, at least it is suggested that dramatic genetic effects caused by the FDNPP accident have not happened on wild plants and animals.
