本文报告了落下灰对家兔皮肤的辐射效应。实验动物依据受照射的种类及剂量的不同分为8组。第1—7组动物所接受的全身吸收剂量为0.4—350拉德,皮肤吸收剂量为0.2—12208拉德;第8组用落下灰制成的贴敷源贴敷,皮肤的吸收剂量为215—13800拉德。经过长期观察,发现放射性落下灰对动物不仅引起体表损伤,而且也引起内污染及放射病。局部皮肤损伤与全身损伤有相互加重的作用。落下灰对动物的皮肤损伤与其他射线引起的类同,但全部实验家兔的皮肤无水泡出现。整个观察期间发现皮肤伤面的糜烂、上皮化有周期性的变化,有些家兔有毛色变异及颈部的粘液性水肿。但所有动物未发现皮癌。
This article reports the radiation effects of falling ash on rabbit skin. The experimental animals were divided into 8 groups according to the type and dose of irradiation. Group 1-7 animals received systemic absorbed dose of 0.4-350 rad, skin absorbed dose of 0.2-12208 Rad; group 8 with a drop of ash made of sticking source application, the skin absorption dose of 215 -13800 rad. After long-term observation, it was found that radioactive fall ash not only causes body surface damage to animals, but also causes internal pollution and radiation sickness. Local skin injury and systemic injury have mutual aggravate effect. Falling gray skin damage to animals and other rays caused by the same, but all experimental rabbit skin blisters appear. Erosion of the skin wound surface was found throughout the observation period with periodic changes of the epithelialization, and some of the rabbits had gross color variation and myxedema of the neck. However, no skin cancer was found in all animals.
