Journal ArticleDOI
Eye lens monitoring for interventional radiology personnel: dosemeters, calibration and practical aspects of H-p(3) monitoring. A 2015 review

TL;DR: The paper concludes that the use of a dosemeter placed at collar level outside the lead apron can provide a useful first estimate of the eye lens exposure, however, for workplaces with estimated annual equivalent dose to the eye Lens close to the dose limit, specific eye lens monitoring should be performed.
Journal ArticleDOI
Review of skin dose calculation software in interventional cardiology.
Françoise Malchair,Jérémie Dabin,Marine Deleu,Marta Sans Merce,Olivera Ciraj Bjelac,Aoife Gallagher,Carlo Maccia +6 more
TL;DR: Large differences among vendors made it clear that work remains to be done before an accurate and reliable skin dose mapping is available for all patients.
Journal ArticleDOI
Investigations into the basic properties of different passive dosimetry systems used in environmental radiation monitoring in the aftermath of a nuclear or radiological event
Željka Knežević,Marija Majer,Zuzanna Baranowska,Olivera Ciraj Bjelac,G. Iurlaro,Nikola Kržanović,F. Mariotti,Marijana Nodilo,S. Neumaier,Katarzyna Wołoszczuk,Miloš Z. Živanović +10 more
TL;DR: The performance of 12 passive dosimetry systems was examined in radiation fields of different photon energies, angles of incidence and ambient dose equivalent rates in order to estimate their performance in the almost omni-directionally and energetically broad radiation field of the natural environment.
Journal ArticleDOI
Accuracy of skin dose mapping in interventional cardiology: Comparison of 10 software products following a common protocol.

TL;DR: In this article, the capabilities and accuracy of several skin dose mapping (SDM) software products were assessed on X-ray systems from the main manufacturers following a common protocol, and the MSD estimates generally agreed with the measurements within approximately 40% for fundamental irradiation set-ups and simulated procedures.
Journal ArticleDOI
A European perspective on dental cone beam computed tomography systems with a focus on optimisation utilising diagnostic reference levels
Teemu Siiskonen,Aoife Gallagher,Olivera Ciraj Bjelac,L. Novák,Marta Sans Merce,J Farah,Jérémie Dabin,Françoise Malchair,Željka Knežević,Mika Kortesniemi +9 more
TL;DR: In this article, the authors conducted a survey to identify existing practices in Member States and found that patient doses are still not properly optimised and diagnostic reference levels (DRLs) are largely not established.
