Background Natural disasters have been frequent in recent years. Effective treatment of patients with cardiovascular disease following natural disasters is an unsolved problem. We aimed to develop a comprehensive surgical treatment shelter to provide emergency interventional services for patients with critical cardiovascular disease following natural disasters. To evaluate the radiation and protection measures through monitoring c-arm X-ray machine radiation in the comprehensive surgical treatment shelter. We evaluate the radiation and protection measures through monitoring c-arm X-ray machine in the comprehensive surgical treatment shelter.

Methods The radiation dose detectors were used to evaluate the abdominal radiation dose rate when the surgical personnel were next to the c-arm X-ray machine with or without lead shade protection etc. The operation was carried out in nine perspective method detection that was the anteroposterior, head, right shoulder and foot position.

Results Blocked significantly lower radiation dose than the various parts of the storm drain (the unit uGy/h), anteroposterior (7.89 ± 0.19 to 229.80 ± 1.30, P < 0.001), head position (16.86 ± 0.11 to 255.20 ± 1.30, P < 0.001); right shoulder (32.38 ± 1.38 to 249.00 ± 1.22, P < 0.001); right former inclined (37.84 ± 0.35 to 134.60 ± 1.52, P < 0.001); left shoulder (38.20 ± 0.07 to 282.40 ± 1.14, P < 0.001); left front inclined (26.54 ± 0.15 to 276.00 ± 1.22, P < 0.001); liver (36.50 ± 0.19 to 126.00 ± 1.22, P < 0.001); spleen (34.36 ± 0.21 to 261.00 ± 1.00, P < 0.001); foot (36.44 ± 0.22 to 149.00 ± 1.00, P < 0.001).

Conclusions Although the radiation safety in the square cabinet c-arm X-ray machine intraoperative application was really high, the radiation in the teach area cannot be ignored, and we still need to strengthen the protection measures.
