Abstract Objective To explore the influences of the scattering and leaking rays from X-ray machines on the area of the room of the machines installed and the design parameter.Methods Measurements of the distributions of scattering and leaking rays from eight types of medical diagnostic X-ray machines were made.Results The reduction of intensities of scattering and leaking rays obey approximately the index law and mainly depend on the performances of X-rays machine used.Conclusion The design of machine room should take such factors as the performance of the X-ray machine, the commodity value of the land and the distribution of people potentially affected, into potentially affected, into consideration in order to realize optimization of radiation protection.
