| Research Abstract |
Confidence in food was required after broad area radiation contamination caused by nuclear accident in the Fukushim Daiichi nuclear power plant. In this study, an inexpensive radiation detector measuring radioactivity for retail shops and/or direct marketing farmers. This detector was designed to made best use of self-shielding of food itself. In size of 1.25 x 1.25 x 3.0 cm^3 of CsI(Tl) scintillator was assumed, and it was reveled to achieve screening level of 50 Bq/kg within 22 minute for rice in 5 kg. In addition, it took only several minutes to determine that radioactivity is lower than 100 Bq/kg.
