We will explain the characteristics of our gamma-ray irradiation device and examples of irradiation for each polymer!
The industrial use of gamma rays is being conducted in various aspects of our lives, primarily in industries such as manufacturing, healthcare, and agriculture. In particular, gamma-ray sterilization of medical devices, food packaging materials, and inspection instruments is expanding year by year. Many of these products use polymer materials as key components such as housings and lids. However, gamma-ray sterilization can cause issues such as degradation and discoloration depending on the polymer materials used. For more detailed information, please refer to the related catalog.

Company information
Koga Isotope Co., Ltd. was established in 1981 as a contract service company for gamma-ray irradiation. We provide contract services for radiation sterilization (gamma sterilization), disinfection, and modification of polymer materials through gamma-ray irradiation. Gamma-ray irradiation contributes to health and safety in sterilization and disinfection applications for medical devices, food, and pharmaceutical packaging materials, and is also applied in the modification of polymers, leading to the development of various applications such as high-performance battery materials and water-absorbent polymers. Koga Isotope has obtained ISO 9001, ISO 13485, and ISO 11137 certifications, establishing a quality assurance system that allows customers to confidently request irradiation and microbiological testing. Additionally, we have three irradiation devices and a sterilization research center, enabling us to provide a wide range of irradiation services from low to high doses and from small to large products, as well as to examine sterilization conditions and conduct microbiological testing and training, offering total services in sterilization. Furthermore, we continuously evolve to better serve our customers by acquiring licenses for cosmetics and pharmaceutical manufacturing and introducing rapid microbial identification devices (MALDI TOF/MS).
