Some problems which the attention has been recently paied to in radiation protection in underground mining are presented and discussed with author's reviews in this paper. These problems involve evaluation of radia tion hazards, estimation of annual limit of a-potential energy exposure, selection of radioactive monitoring methods and improvement of ventilation effectiveness

本文介绍了近年来地下矿山辐射防护研究中值得注意的几个问题,其中包括评价辐射危害、确定α潜能年暴露量限值、选择辐射监测方法和提高通风效果等,并对这些问题进行了讨论。

It has been identified by many works that the radiation de-triment to residents from indoor radon is primarily from inhalation of sh- ort-lived decay products of the radon.It is,therefore,of vital importan-ce to study sources and behaviour of radon daughters in indoor air andthe measures for reducing concentrations of radon daughters Concentrationof condensation nuclei(e.g.aerosol or smoke)in the air is the main fact-or influencing the rates of adhesion and deposition for Rn daughters.Ma-thematical relationship...

Ozone plays an important role in the Earth's ecological environment owing to its strong absorption of biologically damaging incoming ultraviolet light. The possibility that the stratospheric ozone could be depleted has been a burning question over since the discover of ozone hole in Antarctic vortex. It has been confirmed that ozone depletion is caused by catalytic reaction of the chlorine monoxide dimerise and reaction between BrO and CIO, it is promoted by the polar stratospheric clouds. Ozone hole is already having :an effect on populated region of lower latitude as a result of transport of air after the spring bread-up of the Antarctic vortex. Otherwise, volcanoes are one significal source of stratospheric chloride and inject sulphuric acid aerosols which may be comparable to polar stratospheric cloud, therefore they might have played a part in the depletion of stratospheric ozone. The phase-out of long-live CFCs production and development of substituting short-live CFCs is needed in order to-decrease the risk of greater ozone depletion.

臭氧具有强烈吸收紫外线作用,使生物免遭紫外线辐射危害.自南极旋涡里出现臭氧洞以来,平流层臭氧损耗成为当今全球性环境问题之一.实验证实:Cl0-ClO两聚化及BrO-ClO的催化反应有效地将臭氧分子转化成氧分子,旋涡里出现的极地平流层云加速了催化反应损耗臭氧的速率.随着暮春旋涡消散,臭氧洞弥合过程空气的稀释作用,将影响低纬度地区臭氧时空分布.此外,火山喷发的硫酸气溶胶亦具有类似于极地平流层云作用.同时火山喷发也是大气氯化物排放源之一.因此火山喷发具有一定损耗平流层臭氧能力.为了保护臭氧层,限制生产和使用长寿命CFCs,研制和推广短寿命的CFCs替代物是很必要的.
