本刊1992年第1期介绍过德国东部Saxony州和Thuringia州的铀矿区铀生产所带来的一些环境问题。本文继续报道德国统一后对该地区进行地下矿井治理和地表复原的进展情况。这项耗资130亿马克的庞大治理计划将延续10～15年。几个已完成治理工作的废石堆已能继续在地表进行农业耕作,或将辟为公园,或将在其上建设居民区。监测区的氡测量结果表明,低于德国联邦辐射防护委员会推荐的居民区室外氡浓度限值80Bq·m~(-3)。
No. 1, 1992, introduced some of the environmental problems posed by uranium production in uranium mines in the states of Saxony and Thuringia in eastern Germany. This article continues to report on the progress of underground mine management and surface rehabilitation in the region following the reunification of Germany. The massive governance plan of 13 billion marks will last 10 to 15 years. Several waste rock piles that have completed their governance work have been able to continue farming on the surface or to open parks or build residential areas on them. Radon measurements in the monitoring area show that it is below the outdoor radon concentration limit of 80Bq · m -3 recommended by the German Federal Commission on Radiological Protection.
