Safety and Protections

The World Health Organization (WHO) declared in 1980 that foods irradiated with X-rays of 10 kGy or less are free from toxicity, nutrient content, and microbiological aspects. The dose of our X-ray foreign matter detector is less than 0.001 Gy, which is much lower than the WHO recommendation.

Protection for Human

We are always exposed to radiation. The annual amount of exposure a human receives is approximately 1100μSv/h (the dose limit of the International Radiation Defense Committee), and approximately 300μSv is exposed when a chest X-ray is taken. The leakage dose of our X-ray foreign matter detector is less than 1μSv/h.

* 2000h = 8 hours per day, 5 days per week and 50 weeks per year (notified by the Ministry of Science and Technology of the Atomic Energy Act) (1.4mSv / 200h)

USA FDA 21CFR Chapter 179 21

X-ray tube -> Jabis X-ray up to 120 kV in terms of output of up to 500 kV or less radiation sources for inspection in food, packaged food and food processing processes.

United States CDC(Centers for Disease Control and Prevention)

The safety of food resulting from radiation sterilization was studied through tests on animals and humans, and these studies were conducted through generations of animal testing.

the United Kingdom FSA(Food Standards Agency)

Radiological sterilization of food has nothing to do with food safety. Food passed through the X-ray airport inspector is also absolutely safe with a 0.5 Gy exposure. ▶ XAVIS X-ray 0.006Gy


The vast amount of research conducted worldwide has proven that food research using radiation energy is the cleanest and safest way to store food, while the United Nations' International Atomic Energy Agency (IAEA), the Food and Agriculture Organization (FAO), and the World Health Organization (WTO) actively encourage the use of this technology in terms of solving food problems and promoting hygiene and health.

  • 1980 FAO/WHO/IAEA Joint Special Committee on Food Investigation (JECFI)
    Announcing that no food irradiated with radiation to an average of 10 kGy causes no toxicological disturbances at all, no more toxicological tests are necessary, and no more nutritional and microbiological problems.
  • 1997 FAO / WHO / IAEA Joint Study Group Meeting on High-Dose Irradiation
    After reviewing the chemical, toxic, nutritional, and microbiological studies of food irradiated with doses of more than 10 kGy, we concluded that food irradiated under the appropriate conditions, even if it is more than 10 kGy, is safe and nutritionally suitable.
  • XAVIS X-ray food foreign body detector's irradiation dose is about 0.006Gy, much less than recommended.
  • commercial use of food irradiation
    The United States, Japan, China, France and Germany have already used radiation irradiation worldwide to ensure the hygiene and quality of food in dried vegetables, spices, meat, frozen foods, fruits, etc.
  • On February 2, 1997, the Food and Drug Administration (FDA) allowed irradiation of red meat.
  • the amount of human exposure
    We are always exposed to radiation. The natural exposure that humans receive per year is around 2.4 mSv, and approximately 1.0 mSv is exposed on a chest X-ray.According to Article 65 of the Atomic Energy Act and Article 63 of the Enforcement Rules of the Atomic Energy Act, the legal reference dose has a surface radiation dose rate of 10 μSv/h or less at a distance of 10 cm from the surface.
    The surface radiation dose rate of the XAVIS X-ray food foreign body detector is less than or equal to 1 SSv/h at a distance of 10cm above the surface, so it is less than the prescribed value.
