| Abstract | 「要旨」131I投与患者と接触する第三者への被曝線量に基づいて患者の帰宅・帰室の基準を検討した. 主婦とその家族の接触度調査をもとに家族への外部被曝線量を計算し, 患者と家族の距離および年齢との依存関係を明らかにした. 次のような基準値を得た. (1)家庭へ帰宅する場合, 患者と夫の就寝距離が50cm以上でかつ子供の年齢が1歳以上であれば体内保持量は0.51 GBq以下である. 体内保持量が0.2 GBq以下の場合は家族に対する制限は必要ない. (2)一般病室へ帰室する場合, 131I投与患者との距離が2.0m, 25mのとき, 体内保持量はそれぞれ28 MBq, 41 MBq以下である. 第三者被曝に寄与する他の因子の基準値への影響を分析する方法論的基礎を確立したものと考える. |

| Abstract | [Summary] This paper describes levels for discharge from hospital and return to general ward of patients treated with 131I. The level was determined by compairing the possible exposure dose to those individuals whom the patients are in daily contact with the anual dose limit for the public. The external exposure dose was calculated by using the data on the distance between the patient and individuals, length of the time spent at each distance, and each individual's age. The following levels were obtained: (1) For the patient to be discharged from the hospital, the maximum residual radioactivity should be less than 0.51 GBq if the distance from the patient in bedroom is 50 cm or more and the ages of her children are all over one year. No restriction is needed for the patient with residual radioactivity of 0.20 GBq. (2) For the patient to be returned to the general ward, the maximum residual radioactivities should be 28 MBq and 41 MBq, corresponding to the distance from the patient of 2.0 m and 2.5 m respectively. We established a method to analyze the factors affecting the level. |
