Abstract

We developed an emergency national manual for preservation of cultural heritage using irradiation disinfection technic under flood disaster. And we examined its practicality with a critical radiation dose on fungi that occur at water-logged event in order to prevent fungal damage that occurs during submersion. The X-ray irradiation for this experiment was conducted at the Production Technology Research Institute located in Yeongcheon, Gyeongsangbuk-do. A disinfection critical dose of 12 kGy was selected for two types of fungi known to spread rapidly and are resistant to radiation to submerged cultural properties, and this experiments were conducted by setting a target dose of 12kGy at 8.37mA at 5MeV. Under the above conditions, only continuity of irradiated samples were completely disinfected. This suggests that continuity of irradiation is important for fungal disinfection.
