Measures to reduce radiation exposure during interventional procedures
Measures to reduce radiation exposure during interventional procedures
Lower the rate of fluoroscopy
Minimize the use of cinefluoroscopy which has 10 times higher radiation dose
Proper use of collimation
Maximize the distance between the operator and X-ray source
Doubling the distance reduces exposure to one fourth
Avoid left anterior oblique projection which gives maximum scatter radiation to operators
These measures are in addition to routine precautions of using lead apron, thyroid shield, lead glasses, radiation protection caps and if available, lead shields for the legs. Hanging lead shields protect scatter from the image intensifier. Lead shields below the table reduces radiation from the X-ray source. Personal dosimeters should be used always and real time dosimeters if available.
