Regarding radiation exposure to staff, the X-ray Ordinance, which does not apply for patients, requires compliance with body dose limit values.

Wearing protective clothing, due to its inherent weight, also leads to the physical stressing of the person concerned. As a rule, dosimeters are worn underneath the protective apron, so that the measured values remain low.

Furthermore, the average fluoroscopy duration of five hours per week (assumed) is very low with regard to the intensive capacity uti- lization in modern radiology.
