| 内容記述 | Radiocesium (134Cs+137Cs) concentrations in foods are of great concern since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident as people want to avoid receiving additional internal dose from ingestion of the radionuclide. Food monitoring has been carried out, and, if any food exceeds the Japanese standard limit for radiocesium, that is, 100 Bq/kg-wet, the food name together with the producing district has been reported immediately by the Ministry of Health, Labour and Welfare (MHLW). Every month, radioactivities of more than 20,000 samples are being measured and the most recent data of April 2014 (MHLW, 2014) showed that foods exceeding the standard limits were mostly from the wild (that is, not commercially grown or raised). One of the public’s main concerns is how to decrease ingestion of radiocesium from foods, especially foods they have collected from the wild as well as from their home-grown garden vegetables because radioactivities in these foods have not been measured for many cases. Unfortunately, radiocesium removal data by food processing, including culinary preparation, for crops commonly consumed in Japan have been very limited because of little interest in the topic before the FDNPP accident. To remedy this, we have begun collecting such data (Tagami et al., 2012; Tagami and Uchida, 2013). Recently, the Radioactive Waste Management Funding and Research Center (RWMC) compiled the radiocesium removal ratios by food processing using open source data published mainly in 2011 and 2012 (RWMC, 2013). In the present study, we focused on food processing effects on radiocesium removal in food plants from the wild to add more information and we compared obtained values with previously compiled values in the IAEA Technical Report Series No. 472 (2010). We also measured potassium-40 concentrations in the same samples for comparison with radiocesium. |
