Results of concentrations of radioactive cesium in milk. (2024)

We monitored milk product samples that are commercially distributed in the market this year as well.The add-ups are below.The unit is mBq/kg. Please be careful not to misread.If you single-click on the table of the results, images will be magnified and will get easy to see.


Results of concentrations of radioactive cesium in urine. (2023)

We put the results of urine monitoring from January to December 2023 together. 
(N=159, We picked up only the first result of those who were monitored multiple times.)  

Below are the results of radiation measurement.

Comparison of Cesium-137 Concentrations in Seawater after Radioactive Contaminated Water Release

On August 24, 2023, the discharge of radioactive contaminated water from
Fukushima Daiichi Nuclear Power Station (FDNPS) began.

We collected seawater samples around FDNPS in December of that year and
analyzed the concentration of radioactive cesium-137 to compare with the
data before the release.

Radioactive cesium concentration analysis was performed using the
AMP(Ammonium molybdophosphate) method in cooperation with CNIC.

Results of measurement of radioactive cesium in yogurt.(2023)

In December of last year, measurements were conducted on 11 different brands of commercially available yogurt. Below is a summary of the measurement results:

  • mBq/kg represents 1/1000 Bq/kg. ND stands for Not Detected, and NA stands for Not Applicable.
  • Please note that even if the product names are the same, the origins of the raw milk may vary.
  • The selection of brands is at the discretion of the measurement requester.
