铍及其化合物,由于特有的物理、化学性质,已被广泛用于空间技术、原子能反应堆、电子及国防各工业部门。铍对人体的危害早已为世人所知,通常把接触铍及其化合物而引起以肺部肉芽肿病变为主要表现的全身性疾病称慢性铍病。目前本病的诊断主要依据确切的职业史和胸部 X 线检查。为了探讨我国铍作业工 Beryllium and its compounds, due to its unique physical and chemical properties, have been widely used in space technology, atomic energy reactors, electronics and defense industries. Beryllium hazards to the human body has long been known to the world, usually caused by contact with beryllium and its compounds caused by pulmonary granuloma lesions as the main manifestation of the generalized disease known as chronic beryllium disease. The current diagnosis of the disease is mainly based on the exact history and chest X-ray examination. In order to explore our beryllium workers
