Fukushima Prefecture during the Great East Japan Earthquake. (a) Fukushima Prefecture, lying to the northeast of Tokyo, and Miyagi and Iwate Prefectures, located to the north of Fukushima, were severely damaged by the quake and tsunami caused by the Great East Japan Earthquake. (b) Locations and geographical area classifications of the six study hospitals. 1. Public Soma General Hospital (Soma City), 2. Fukushima Rosai Hospital (Iwaki City) in Area 1, 3. Fukushima Medical University Hospital (Fukushima City), 4. Ohara General Hospital (Fukushima City), 5. Japanese Red Cross Fukushima Hospital (Fukushima City) in Area 2, 6. Fukushima Prefectural Aizu General Hospital (Aizuwakamatsu City) in Area 3.

(a, b) The radioactive concentrations of radiocesium, ¹³⁴Cs (a) and ¹³⁷Cs (b), in each part of the bamboo shoots collected in Date, Fukushima Prefecture (41 km from Fukushima Daiichi). (c, d) The radioactive concentrations of radiocesium, ¹³⁴Cs (c) and ¹³⁷Cs (d), in each part of the bamboo shoots collected in Ichikawa (215 km from Fukushima Daiichi) and Kashiwa (195 km from Fukushima Daiichi) in Chiba Prefecture. NS indicates not sampled. (e, f) The radioactive concentrations of radiocesium, ¹³⁴Cs (e) and ¹³⁷Cs (f), in each part of the bamboo shoots collected in Aizuwakamatsu in Fukushima Prefecture (102 km from Fukushima Daiichi) and Annaka in Gunma Prefecture (225 km from Fukushima Daiichi). Error bars indicate measurement deviation.

Local collection cities are aligned from northern (left) to southern (right). Fukaura City is in Aomori Prefecture, Sendai and Shiroishi Cities are in Miyagi Prefecture, and Fukushima, Koriyama, and Shirakawa Cities are in Fukushima Prefecture. Forewing sizes are shown in blue or pink square symbols, and average temperatures are shown in orange diamond symbols. Data points and error bars indicate mean ± SD. The populations found in Fukushima and Koriyama City are shaded in blue and pink, respectively. Any prefecture that significantly differed (p < 0.05) from the Fukushima or Koriyama populations is indicated with its p-value. (a) Males in the fall of 2012. (b) Females in the fall of 2012. (c) Males in the fall of 2013.

Notes. The tsunami generated by the Great East Japan Earthquake hit the Fukushima Daiichi Nuclear Power Plant, causing a nuclear disaster in Fukushima Prefecture. The location of the Fukushima Daiichi Nuclear Power Plant is circled. Regions colored in dark gray correspond to municipalities where evacuation orders were issued for the total area (total evacuation areas: Naraha, Tomioka, Okuma, Futaba, Namie, Katsurao, and Iitate). Regions colored in light gray correspond to municipalities designated as terminated/partial evacuation areas (Tamura, Minami-Soma, Kawamata, Hirono, and Kawauchi). Uncolored municipalities correspond to non-evacuation areas.
Total evacuation areas: Naraha, Tomioka, Okuma, Futaba, Namie, Katsurao, and Iitate
Terminated/partial evacuation areas: Tamura, Minami-Soma, Kawamata, Hirono, and Kawauchi
Non-evacuation areas: Other municipalities in Fukushima Prefecture

Residents of Namie were evacuated to other areas after the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. Residents of Nihonmatsu City were analyzed in this study.

Blue is water system: Aga river basin is west area of Fukushima, Abkuma river basin is center of Fukushima. Green is mountain chain or highland where heights is more 1,000 m. Yellow is high contaminated area by nuclear accidents. We created the map using the GIS software which is ‘MANDARA for windows 2000/XP/VISTA/7 Version 9.35' (the software copyright: 1992–2011 Tani Kenji).

Concentric circles indicate the distance from the Fukushima Daiichi nuclear power plant.

The Yotsukura and Ena stations are about 35 and 50 km south of the Fukushima Daiichi Nuclear Power Plant (FDNPP), respectively.
