Abstract:
Object To study on the X-ray protection module in the radiodiagnosis unit to protect X-ray technicians, other medical staffs and etc against radiation during standing and lying X-ray examinations in the tent-form field medical system.Methods A local tightness protection solution was put forward involving in lead protective materials, standing shoot rack,diagnosis couch as well as considerations on the service orientation of the tent-form field medical system and the operation mode of the X-ray tent. A protective support with fast-plug and lateral folding structure was designed based on X-ray radiation protection principle and lead equivalent calculation of the lead curtain. An X-ray protection module was developed with the lend curtain, protective support, warning sign and etc.Results The dose peaked at vertical direction, and at vertical direction the annual dose to the public 1 m away from the tent was 78.8μSv which was far lower than the limit value 1 mSv. The strength of the protective support met the requirements, and the maximum deformation of the support bar was 15 mm after the suspension of the lead curtain.Conclusion The X-ray protection module gains advantages in design, structure, operation,rapid deployment and withdrawal, handling and transport as well as protective effective according to GB 18871—2002 regulation, and thus can be used for X-ray diagnosis at peace and war time.
