1, X-ray machine, X-ray machine of the inherent safety performance is the most important link of X-ray protection.Ball control, shading device should not leak X-ray, window containing aluminum filter plate, useful wire into the skin of patients with air exposure rate should be less than 6 r/min.Bulb perspective, especially in bed X line ball tube and its accessories such as a radiation leak, will be subject to direct radiation workers and patients.
2, the time protection: try to shorten the time of X-ray radiation.Before interventional surgery to draw up the strict operating procedures, to understand information related to the patients, try to reduce unnecessary exposure.In operation of the cumulative exposure time should not exceed 30 min, optimize the best exposure conditions, avoid repeated exposure.
3, the distance protection: use increase performer and radiation source (that is, the focus of bulb) and scatterer distance (check), reduce the performer by radiation dose, distance per 1 times, radiation dose to reduce 3/4, X-ray exposure in addition to the performer and main assistant, when other people stay away from, avoid X-ray radiation source.
4, shielding protection: set shield between the X-ray source and the staff, to reduce or eliminate ray radiation, if there is a lead shielding clothes, lead apron, hat, lead glasses, gloves, etc.
