Abstract[Summary] The maximum excretion rates of Iodine in exhalation, perspiration and salivation were measured in patients treated with 131I for thyroid carcinoma and hyperthyroidism. The contamination of dishes, chopsticks, toothbrushes, linen (coversheets, sheets and towels) , and underwear (shirts and drawers) were monitored and evaluated along with the air contamination level arising from these items. The maximum excretion rate of the administered dose for thyroid carcinoma patients was in the range of 7.7×10-6 to 1.2×10-7 per hour in exhalation, 2.4×10-5 per hour in perspiration, and in the range of 7.0×10-3 to 7.1×10-4 per ml in saliva. Hyperthyroidism patient's maximum excretion rate was in the range of 1.4×10-5 to 2.75×10-7 per hour in exhalation, 6×10-6 to 8.6×10-5 per hour per gram in perspiration, and 1.2×10-2 to 1.3×10-3 per ml in saliva. The maximum contamination rate of the administered dose was 1.1×10-4 to 3.8×10-5 for chopsticks, 2.3×10-3 to 2.3×10-4 for toothbrushes, 35×1-4 to 4.6×10-6 for sheets, 1.3×10-4 to 10-5 for coversheets, 2.8×10-4 to 3.8×10-4 for shirts, 1.8×10-3 to 1.3×10-4 for drawers, and 5.4×10-4 to 3.6×10-5 for towels. The maximum air contamination rate ranged 1.4×10-5 to 1.2×10-7 of the administered dose. The decision for release must be done based on the comparison a half of the present annual dose limit with the absorbed dose of houshold evaluated by applying the worst conditions to some parameters. When a patient cannot adequately satisfy our suggested safty parameters, he should not be released from the hospital.
