Radiation shielding of multiple x-ray sources in diagnostic radiology
Abstract:
A unified approach to the problem of barrier thickness calculations for diagnostic x-ray rooms containing multiple x-ray tubes emitting primary, scatter, and leakage radiation is presented. Given the reasonable constraint that all x-ray tubes in a room operate at the same maximum potential (kVp), the required barrier thickness is determined completely and accurately from a single transcendental equation relating the Kux and BLx values calculated for each radiation source separately. A useful approximation to this is discussed and examples given.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
