The hearing and cerebral circulation was evaluated in 100 liquidators ranging from 23 to 50 years of age 1 year and 6 to 8 years after the disaster. Also, the hearing state data was compared from 80 liquidators of the same age dwelling in clean and radionuclide-contaminated areas for 5 to 8 years. The control group consisted of 20 young healthy individuals having no history of contact with radiation. Subjective audiometry, AEP and REG was used. Testing performed indicate that under radiation, more pronounced changes occur in the central part of the acoustic analyser rather than in its receptor system. More impaired were the persons residing the radionuclide-contaminated areas. The liquidators of the ChFS accident who live in clean areas presented with better state of the cerebral circulation and bioelectric brain activity. But over the time, the REG data 6-8 years after the disaster became considerably worse, as compared to the data obtained 1 year after the disaster. It should be emphasized that individual irradiated during and after the Chernobyl disaster require a constant dynamic observation and their identified changes require periodical management. Withdrawal of the liquidators from the contaminated to the clean areas is one of the preventive measures against the hearing and cerebral circulation disorders.
在灾难发生1年以及6至8年后，对100名年龄在23至50岁之间的清理者的听力和脑循环情况进行了评估。此外，还对80名年龄相同、在清洁地区和放射性核素污染地区居住了5至8年的清理者的听力状态数据进行了比较。对照组由20名无辐射接触史的年轻健康个体组成。采用了主观听力测定、听觉诱发电位（AEP）和视网膜电图（REG）。所进行的测试表明，在辐射情况下，听觉分析仪的中枢部分比其感受器系统出现更明显的变化。居住在放射性核素污染地区的人员受影响更大。切尔诺贝利核事故清理者中生活在清洁地区的人员脑循环和脑生物电活动状态较好。但随着时间推移，与灾难发生1年后获得的数据相比，灾难发生6至8年后的视网膜电图数据明显变差。应当强调的是，切尔诺贝利灾难期间及之后受到辐射的个体需要持续的动态观察，对其发现的变化需要定期处理。将清理者从污染地区转移到清洁地区是预防听力和脑循环障碍的措施之一。
