Plutonium (Pu) has been released in Japan by two very different types of nuclear events – the 2011 Fukushima accident and the 1945 detonation of a Pu-core weapon at Nagasaki. Here we report on the use of Accelerator Mass Spectrometry (AMS) methods to distinguish the FDNPP-accident and Nagasaki-detonation Pu from worldwide fallout in soils and biota...

Radiocesium was dispersed from the Fukushima Dai-ichi disaster in March 2011, causing comparatively high radioactive contamination in nearby environments. Radionuclide concentrations in wild rodents (Apodemus argenteus, and Apodemus speciosus) within these areas were monitored from 2012 to 2016. However, whole-organism to soil transfer parameters (...

Natural and anthropogenic disasters have the capability to cause sudden extrinsic environmental changes and long-lasting perturbations including invasive species, species expansion and influence evolution as selective pressures force adaption. Such disasters occurred on 11 March 2011, in Fukushima, Japan, when an earthquake, tsunami and meltdown of...

Genetic effects and radioactive contamination of large mammals, including wild boar (Sus scrofa), have been studied in Japan because of dispersal of radionuclides from the Fukushima Dai-ichi Nuclear Power Plant in 2011. Such studies have generally demonstrated a declining trend in measured radiocesium body burdens in wildlife. Estimating radiation...

The March 2011 Fukushima Dai-ichi Nuclear Power Plant accident in Japan released 520 PBq of radionuclides compared to a total release of 5300 PBq from the Chornobyl Nuclear Power Plant accident. Both nuclear accidents resulted in deposition of radiocesium throughout the northern hemisphere, and a plethora of studies have been performed regarding ra...

Radiological measurement of tissues from wild game meat, including wild boar, has been monitored in Japan as a result of the dispersal of radionuclides from the Fukushima Daiichi Nuclear Power Plant in 2011. Monitoring activities also include the development of data frameworks to estimate internal radiological contamination of animals from radionuc...

The number of Japanese sika deer (Cervus nippon) populations continues to increase contributing to the wide distribution of deer in Japan. However, historically, anthropogenic impacts caused the near extinction of Japanese sika deer in the Tohoku region of Northeast Japan. In recent history, Japanese sika deer have been able to repopulate many part...

The health effects associated with chronic low-dose, low-dose rate (LD-LDR) exposures to environmental radiation are uncertain. All dose-effect studies conducted outside controlled laboratory conditions are challenged by inherent complexities of ecological systems and difficulties quantifying dose to free-ranging organisms in natural environments....

Supplement to Cunningham et al. 2021. Evaluation of DNA damage and stress in wildlife chronically exposed to low dose, low dose rate radiation from the Fukushima Dai-ichi Nuclear Power Plant accident. Provides additional dosimetry information, data and analyses to main paper (published in Environment International).

Hybridization between wild boar (Sus scrofa) and their domestic relative, pigs, is a global issue and gene flow between these populations has been known to negatively impact biodiversity with increased aggression, litter sizes, and growth. However, establishing a cost-effective analysis for long-term monitoring of possible gene flow of wild pigs in...

One of the largest releases of radioactive contamination in history occurred at Japan's Fukushima Daiichi Nuclear Power Plant (FDNPP). Although the accident occurred in 2011, questions still persist regarding its ecological impacts. For example, relatively little is known about radiocesium accumulation in snakes, despite their high trophic status,...

On 11 March 2011, a 9.0 magnitude earthquake struck the Tohoku region of Japan. The earthquake caused a 15 m tsunami that bombarded the east coast of the island nation. Among the losses was the damage to the Fukushima Daiichi nuclear reactor that lost onsite power and was unable to cool the reactor cores. The reactors melted down and released a plu...

The 2011 Tohoku earthquake drastically changed human activities in some regions of Fukushima Prefecture, Japan. The subsequent tsunami damage and radioactive pollution from the Fukushima Daiichi nuclear power plant resulted in the evacuation of humans, and abandonment of agricultural lands, allowing population expansion of wildlife into areas forma...
