Medical ray protective cover

Technical Field

The utility model belongs to the technical field of the safety protection technique and specifically relates to indicate a safety protection equipment that can protect X ray, specifically speaking is a medical ray protection casing that can effectively avoid X ray to the examinee not shoot the position and near personnel cause the injury.

Background

Since exposure to X-ray radiation can be detrimental to health, body parts other than the examination part of the patient should be safeguarded against exposure to the main beam. Some of the effects of X-ray radiation are cumulative and may appear months or years later. The best safety criterion for X-ray operators is "to avoid direct exposure to the main beam at any time". Any object in the path of the main beam generates secondary radiation (scatter). The intensity of the secondary radiation depends on the energy and intensity of the primary beam and the atomic number of the material of the object impacted by the primary beam. The intensity of the secondary radiation may be greater than the intensity of the radiation reaching the film, and protective measures should be taken against it. Lead shielding is an effective measure of protection. To minimize the risk of exposure to radiation, protective devices such as lead screens, lead-impregnated gloves, lead aprons, thyroid guard rings, etc. should be used. The personal protective device (apron, gloves etc.) should contain at least a 0.25mm thick layer of lead or equivalent.
