铀是放射性很强的剧毒物质之一,人们在生产和使用铀的实践中,对其放射性射线的危害途径和如何防护其放射性射线对人体的危害,进行了深入而有效的探索。本文拟结合华东地质学院实验楼工程的铀矿物实验室、陈列室,铀矿床实验室、陈列室(简称铀矿实验室)的设计,谈点粗浅的看法: 一、铀γ、α射线对人体的危害性. 铀矿实验室陈列和使用的铀矿石标本,会辐射出穿透性很强的γ射线。如超过了人体的允许照射剂量,则将对人体产生不同程度的危害。铀矿标本和铀矿石,随着时间的推移而衰变,产生有放射性的氡气。氡进入大气又不断衰变产生放射性更强的氡子体。当实验室工作人员进行呼吸时,氡随空气由呼吸道进入 Uranium is one of the highly radioactive highly toxic substances. In the practice of producing and using uranium, people have carried out an in-depth and effective exploration on the ways of harming their radioactive rays and protecting their radiation ray’s harm to the human body. This article intends to combine the design of the uranium mineral laboratory, the showroom, the uranium deposit laboratory, and the showroom (abbreviated as the uranium laboratory) of the Experimental Building Project of East China Institute of Geology, and to discuss some of the superficial views: 1. Uranium gamma, alpha ray on the human body Harmfulness. Uranium ore specimens displayed and used by uranium labs radiate highly penetrating gamma rays. If it exceeds the allowable radiation dose of the human body, it will have different degrees of harm to the human body. Uranium specimens and uranium ore, which decay over time, produce radioactive helium. As the helium enters the atmosphere, it continues to decay and produces more radioactive radon daughters. When laboratory workers breathe, helium enters the airway with air
