The Research Of The Radon Measurement And The Instrument Of Calibration Technology

Relating to enviorment protection and health, the study about radon and its progeny is a hot topic recent years. The measurement to radon and its progeny is the first step to further study them. Ulteriorly, we can effectually make use of the theory of radom and its progeny to meet our needs. The measurement to radon and its progeny involed many fields in all kinds of subjects, such as nuclear technology, electronics, geoscience, enviorment science and radioactive medicine etc.Our research start with the measurement of radon and its progeny, introduce you sereral measurement ways and corresponding instruments. From experiments,we have accumulated large numbers of dadum which educed common laws of varietion of radon concentration in different conditions in enviorement air.In the process of research, a mini type radon chamber system had accomplished. Due to this system,we have groped much useful experience and theory. Great deals of practice proved that the result was OK to calibrate instruments in variational concetration.Through the basis of minitype radon chamber system, it is convenient to prepare the medium radon chamber system. In this paper, there are many analysises about the choice of radon resource, framework of radon chamber system, the control and supervise of radon concentration and the evaluation of every performance of radon chaber system.In the primary running of he medium radon chamber system, we can gain the conclusion that the chamber only results in low pollution. In the end, there are some resolvents that we can further weaken the pllution.
