Abstract Objective To emphasize the importance using correctly radiation protection survey meter by an analysis of current status in the protection monitoring of X and γ rays in China.Methods The calibration of the survey meter in SSDL should be done for determination of the relation of different reading-type survey meters as well as the correct factor of it.Results Ambient dose equivalent is recommended in the radiation region monitoring for the above 25 keV photons.Conclusion An assessment of protection quantity is put into practice on the basis of ambient dose equivalent converted from the measuring results of survey meters according to the knowledge of a radiation spectrum when the ionization radiation level of the monitoring region is near to the limits of protection quantities.
