Information 2020 production Niigata prefecture sake brewing rice Radioactive material test results

2021th of February 01

XNUMX. Survey and inspection method

  • Target area: 5 points in Niigata prefecture (Kaetsu East, Kaetsu West, Sado, Chuetsu, Joetsu)
  • Target varieties: 2020 Niigata Prefecture "Gohyakumangoku", "Takane Nishiki", "Koshitanrei"
  • Collection method: Brown rice is collected and analyzed at the time of harvest.
  • Analytical organization: Niigata Prefectural Institute for Environmental Health
  • Analytical method: Gamma ray spectrum by germanium semiconductor detector
  • Target nuclides: radioactive iodine, radioactive cesium
  • Lower limit of quantification: 5Bq / kg (becquerel)
    (The lower limit of quantification is the minimum value that can be quantified by the analytical method and the minimum value that the analytical institution can prove based on the measurement.)
