Radioactivity Tests

Radioactive Substance Tests and Raw Material Origins

We started conducting radioactive substance test on manufactured products from November, 2011.
The inspection equipment that we use is “LB2045” highly-sensitive NaI (TI) gamma-ray spectrometer (detection threshold: 1Bq/kg) of BERTHOLD TECHNOLOGIES.
Our product standard for radioactivity is below 4Bq/kg (total of radioactive cesium-134 and -137).
We installed this testing equipment and perform examination on every production. Up until now, there is no report exceeding this standard.

The names of ingredients harvested/supplied after the Fukushima nuclear power plant disaster in 2011 are listed on the page below. When we use such ingredients for our products, we disclose the information and publicize their production origins.
