Abstract：Objective To study and analyze the radiation problems of C-arm X-ray machine in minimally invasive surgery for
unstable intertrochanteric fracture and to propose the protective strategy. Methods The radiation dose level of head, neck, chest,
abdomen and hand of the medical personnel in the operating room under the C-arm X-ray machine was measured by X-ray and
γ-ray dosimeters. The radiation dose difference between the upper and the lower C-arm X-ray machine was compared. The radiation
dose levels of doors, windows, walls and downstairs of the operating room with and without protective measures were measured by
radiation dose patrol instrument, and the radiation protection effects of the operating room were compared. Results The upper C-arm
X-ray machine caused the maximum radiation dose in the hand; the lower C-arm X-ray machine caused the maximum radiation dose
in the abdomen. The radiation level of the head, neck and chest of upper C-arm X-ray machine was significantly higher than that of
the lower model (P<0.05). The radiation dose level outside the door, window and wall of unprotected room was significantly higher
than that of protected room (P<0.05). Conclusion To protect the operating room is the key measure to avoid the radiation damage
of medical staff. If conditions permit, the lower model C-arm X-ray machine shall be used as much as possible to reduce the harm of
radiation to human body
