Accurate calibration services of the highest standards for peace of mind

Our Oarai Research Laboratory calibrates radiation measurement instruments such as survey meters, ion chamber survey meters and personal dosimeters. We also calibrate radiation measurement instruments purchased by customers from other companies.

The secondary standard dosimeters owned by the Oarai Research Laboratory undergo periodic calibration by stipulated standard instruments at the National Metrology Institute of Japan (NMIJ) of the National Institute of Advanced Industrial Science and Technology to meet national Japanese standards. Our laboratory is registered as a calibration company for γ-ray measuring instruments and α/β-ray nuclides under the Japan Calibration Service System (JCSS).

In addition, Oarai Research Laboratory is an international MRA certified company for γ-ray measuring instruments, and can issue accredited calibration certificates valid in countries that have joined the Mutual Recognition Arrangement.
