The entire system of small light hanging electric door (suitable for lead radiologist equivalent protection of small electric sliding doors) A. Drive on radiation protection lead glass to withstand the weight of the four small nylon wheel, aluminum alloy track. Such doors weighing less than 240KG, with square tube welding skeleton mainly manual welding techniques like sliding doors. B. The door to load up the wall, the wall has sufficient load-bearing capacity requirements, the side wall is not as lightweight hollow brick or brick wall, if the wall will have to add these two lintels, track installation should pay attention to a few points: 1) on the power beam or wall drilling; 2) drilling in the power beam and plate; 3) with M10 bolts secured over the track on the beam or wall; 4) Make sure that the power installation horizontal beam, do not run into when installing or cutting power beam track, otherwise it will affect the performance or longevity. C. the doors will be installed along with a good hanging round hanging on the rail, were leveling, cutting sliding freely, inlaid floor after partial blocking rail radiation protection, blocking partial wheel and rail 2-3mm gap should lead equivalent radiation protection, and then fixed explanation. D. Finally, install door opener and tensioners power repeatedly tried the door. To limit the stochastic effects of radiation protection lead door, radiation dose equivalent staff were uniformly illuminated when the body should not exceed 50mSv (5rem). When subjected to non-uniform irradiation, the effective dose equivalent should satisfy the following inequality: ΣT WT HT ≤50MSv (5rem) Where: HT - tissue or organ (T) of the annual dose equivalent, mSy (rem) WT - organization or organ (T) relative risk weighting factor (see Appendix F) ΣT WT HT - called the effective dose equivalent, HE expressed by medical radiation protection | Hebei Ericsson (certified) | radiation protection provided by Ericsson Hebei Medical Engineering Co. .
