Use of effective dose to assess x-ray protective clothing

This review article provides an overview on the results of studies conducted by the authors to
improve the current personal protection concept in the clinical application of x-rays. With the aid
of personal dose equivalent measurements during radiologically guided clinical interventions,
laboratory tests using the Alderson-Rando phantom as well as Monte Carlo simulations various x-ray
application scenarios were investigated. The organ doses and the effective doses of staff persons
standing near the patient were determined. The 3D-attenuation properties of protective clothing
under the scattered radiation emitted by the patient play a special role here. With regard to the
minimisation of the quantity ‘effective dose’ the protection of the lower body from the gonads to
the chest is of particular importance, since 80% of the effective dose is contributed by this region
of the body. In contrast, protection of the back plays a subordinate role. Protective aprons
optimised in terms of...
