Determining the effective energy and scattered radiation distributions in an interventional cardiology department

This study aims to determine effective energy and scattered radiation distributions in an interventional cardiology department. Additionally, the protective effectiveness of ceiling-suspended shielding was investigated. Optically stimulated luminescence dosemeters were attached to mica rods to determine effective energy and scattered radiation at numerous points in the catheterization laboratory. The effective energy of the scattered beam ranged from 40 to 50 keV, with the beam scattered to the eye position reaching an effective energy of 45 keV. Radiation was distributed nonuniformly at different locations and heights. Ceiling-suspended shielding reduced the dose to the head and neck region but did not significantly affect other regions. The combination of a suitable standing position and ceiling-suspended shielding can notably diminish the staff's eye dose by >93%.
