| As we know, nowadays radon has been a hot topic, especially. Radon and its progency have exerted great influence on human health, which are raised universal attention on them.The measurement on radon and its progency are complex problems, they involve in multi-discipline fields, such as nuclear science, technology of electronic science, geoscience, environment science and radioactive science, etc. this paper start from basic theory, introducing the fundamental theories of radon, the ways of radon measurement and the classification of instrument for measure radon as well as alternative means of measure radon.On the basis of using the principle of unsteady radon concentration and self-constructing equipment of standard detecting, this paper elaborate at some length the form construction of the detecting and the corresponding function principle. And through plenty of experiences, trying to make properties study on the standard detecting, for example, seal, uniformity, radon distribution come to mean time, effect of temperature and humidity on radon concentration and impact of waste gas on environment, and so on. It is proved that the equipment of standard detecting is stability of function and safety credibility, it is applicable to calibration and regulation of instrument of radon measurement, for instance, moment instrument, accumulate instrument and accumulation collector. |
