We experimentally evaluated the absorption fraction in gastrointestinal system of Cs-137 in wild boar meat contaminated by the Fukushima Daiichi Nuclear Power Plant accident. Wild boar was hunted in difficult-to-return zone in December 2017. For three parts of the meat (Loin, Brisket, Round), extraction tests were performed based on in-vitro digestion method by Minekus et al. (2014). From this test, the extraction rate in small intestinal was evaluated as 89%3%.
