氡及其存在行业氡是一种惰性金属原子,在空气中能产生衰变,氡原子的衰变产物被称为氡子体。氡子体为金属离子,主要通过呼吸道进入人体后在整个呼吸道中长期定居,随年龄增加,氡子体不断增多地在肺部“行凶”。氡存在的行业大致有3类:一类是核工业系统,如放射性矿物的开采、冶炼和加工工人,以及核反应堆、核电站的操作工;第二类是放射 Radon and its Presence Radon is an inert metal atom that produces decay in the air. The decay products of radon atoms are called radon progeny. Radon progeny as metal ions, mainly through the respiratory tract into the human body after the long-term settlement throughout the respiratory tract, with age, radon progeny in the lungs continue to increase. There are roughly three types of industries in which radon exists: the first category is the nuclear industry systems, such as the mining, smelting and processing of radioactive minerals, and the operators of nuclear reactors and nuclear power stations; the second category is radiation
