초록
Gamma ray dose reduction occurs when gamma rays interact with irradiated sampleand lose energy. This dose reduction also can be affected by water content of sample, waterqualities, water properties. Flooded cultural heritages are saturated with moisture, and havehigher density than dry conditions. For this reason, it may cause increases in dose reductionand decreases effcts of gamma ray sterilization. The aims of this study was to understand thechracteristics of gamma ray irradiated water samples and water saturated samples. Irradiatiedwater samples and non-irradiated water samples of various qualities were analyzed in this study. Dry paper samples and flooded paper samples were also irradiated and their absorbed doseswere compared to each other. As a result, water samples had diffrences in properies, but therewere few changes after gamma irradiation. Flooded paper samples had higer dose reductions,but water qualities caused few diffrences of dose reduction. Therefore, dose reduction caused bywater saturation should be considered in gamma ray sterilization of flooded cultural heritage. Futhermore, traditional samples, such as Hanji and Silk, should be considered in additionalstudies.
Abstract
Gamma ray dose reduction occurs when gamma rays interact with irradiated sampleand lose energy. This dose reduction also can be affected by water content of sample, waterqualities, water properties. Flooded cultural heritages are saturated with moisture, and havehigher density than dry conditions. For this reason, it may cause increases in dose reductionand decreases effcts of gamma ray sterilization. The aims of this study was to understand thechracteristics of gamma ray irradiated water samples and water saturated samples. Irradiatiedwater samples and non-irradiated water samples of various qualities were analyzed in this study. Dry paper samples and flooded paper samples were also irradiated and their absorbed doseswere compared to each other. As a result, water samples had diffrences in properies, but therewere few changes after gamma irradiation. Flooded paper samples had higer dose reductions,but water qualities caused few diffrences of dose reduction. Therefore, dose reduction caused bywater saturation should be considered in gamma ray sterilization of flooded cultural heritage. Futhermore, traditional samples, such as Hanji and Silk, should be considered in additionalstudies.
