It was in 1954 when we inherited the electron tube and electronics technology and developed our own radiation measurement systems based on the predecessor's technology.

Since then, we have supplied numerous state-of-the-art radiation measuring systems to radioisotope handling facilities in atomic power facilities, universities, research centers, hospitals, etc.

Our radiation measuring systems range from light weight, compact units to multifunctional systems incorporating total data processors. Each system maintains high reliability in terms of high-level performance.

Ever since the East Japan Disaster in 2011, our systems have become standard instruments for various radiation measurements throughout Japan.
