Scattered X-ray intensities from fluoroscopy units

This excerpt was created in the absence of an abstract.

We refer to the protection afforded by multileaf Pb aprons on fluoroscopy units and would like to offer our own illustrative example of the importance of such measures in shielding against scattered radiation. Our concern lies with an incident that occurred in a hospital and which involves a fluoroscopy unit (a Siemens Gigantos with a 100 kW multipulse generator capable of delivering 1000 mA and 150 kVp) that was operated in the absence of its protective Pb aprons. Figure 1 shows the image of a gastrointestinal tract (using Curix Agfa Gevaert X-ray film and a CaWO₄ normal-speed screen combination) and a superimposed forearm (not that of the patient).
