Abstract

Ingestion of radionuclide contaminated food is one of the major concerns in long-term exposure following a nuclear accident. A terrestrial food chain model was developed to evaluate radioactivity in terrestrial food and ingestion doses under the Korean agricultural environment. The influence of the radionuclides released from the Fukushima Daiichi Nuclear Power Plant accident on contamination of agricultural food and livestock produced in Japan and the ingestion doses for people living in Fukushima Prefecture was calculated using the developed model.

Notes

  1. Attachments for the 2013 UNSCEAR report are available on http://www.unscear.org/unscear/en/publications/2013_1.html.

  2. The regions considered in this study referred to the classification of geographic areas from the 2013 UNSCEAR report [1]. The evacuated regions, in which people were evacuated within months after the FDNPP accident according to evacuation scenarios, include Futaba, Hirono, Namie, Naraha, Okuma, Tomioka, Iitate, Kawamata, Minamisoma, Tamura, Kawauchi, and Katsurao.

  3. According to the 2013 UNSCEAR report [1], restriction of food supplies was introduced by the Japanese authorities to limit radiation exposure of the Japanes public from March 2011 to the end of March 2012. Limitation levels of radionuclides for foods are as follows. Iodine: 300 Bq kg−1 for milk, 2000 Bq kg−1 for other foods; cesium: 200 Bq kg−1 for milk, 500 Bq kg−1 for other foods. After April 2012, lower values were introduced for cesium: 50 Bq kg−1 for milk, 100 Bq kg−1 for other foods.
