Efficient reinforced medical building ionizing radiation protection system easy to construct

The invention relates to an efficient, reinforced and easy-to-construct medical building ionizing radiation protection system which is a six-surface radiation protection system defined by keels and lead plates and specifically comprises a ground floor, a top floor and four base layer walls. A top lead plate is arranged below the top floor, the top lead plate is fixed through a top lead plate framework, the top lead plate framework comprises a load-bearing steel framework and a U-shaped through keel, the load-bearing steel framework is fixed through expansion bolts, and the U-shaped through keel is fixed through fasteners; a square tube keel is arranged on the surface of the base layer wall body, a base layer lead plate is arranged on the surface of the square tube keel, and the keel frame and the base layer lead plate are fixed through fasteners; and a ground lead plate is arranged above the ground floor. Through protection of a six-face lead plate system, medical equipment radiation leakage is effectively pr
