2022 December 01

XNUMX. Survey and inspection method

• Target area: 5 points in Niigata prefecture (Kaetsu East, Kaetsu West, Sado, Chuetsu, Joetsu)
• Target varieties: "Gohyaku mangoku", "Takane Nishiki", "Koshitanrei" from Niigata prefecture, produced in 3rd year of Reiwa
• 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.)

XNUMX, test results

"Gohyaku mangoku" from Niigata prefecture (3rd year of Reiwa)

* Not detected ... Indicates that the value is below the lower limit of quantification for each nuclide to be inspected.

"Takane Nishiki" from Niigata Prefecture (3rd year of Reiwa)

* Not detected ... Indicates that the value is below the lower limit of quantification for each nuclide to be inspected.
* Untested because the sample brown rice from Sado of "Takane Nishiki" produced in Reiwa 3 was not available.

"Koshitanrei" from Niigata prefecture (3rd year of Reiwa)

* Not detected ... Indicates that the value is below the lower limit of quantification for each nuclide to be inspected.
