Interventional radiologists have the highest exposure to radiation among medical staff working with X‑ray techniques . In recent years, the dramatic improvements of the imaging devices allowed to increase the number of clinical tasks that can be performed in interventional radiology. As a result, the number of procedures continues to rise. The occupational dose is currently determined by means of physical dosimeters. Doses to the trunk are monitored routinely, but this sole quantity is often not indicative of the doses delivered to other parts of the body. In fact, in interventional radiology the tissues that may be exposed to higher doses are those in the head and in the hands. The dose to the hands is a matter of concern because of the need for the operator to be close to the X-ray field to carry out manipulations, and the possibility of higher doses from poor practice if the hands are exposed to the primary beam . However, monitoring those body parts would require the staff to wear several (special) dosimeters. This is not practical nor ergonomic to the operators; furthermore, the sensitivity of such dosimeters would be greatly affected by the angular and energy responses. In line with the current trends and necessity for real-time dose monitoring, we are working towards an innovative approach to determine occupational exposures. Instead of using dosimeters, our methodology is based on computational simulations.
