Active personal dosemeters in interventional radiology: tests in laboratory conditions and in hospitals
2011
The work package 3 of the ORAMED project, Collaborative Project (2008–11) supported by the European Commission
within its seventh Framework Programme, is focused on the optimisation of the use of active personal dosemeters (APDs) in
interventional radiology and cardiology (IR/IC). Indeed, a lack of appropriate APD devices is identified for these specific
fields. Few devices can detect low-energy X rays (20–100 keV), and none of them are specifically designed for working in
pulsed radiation fields. The work presented in this paper consists in studying the behaviour of some selected APDs deemed
suitable for application in IR/IC. For this purpose, measurements under laboratory conditions, both with continuous and
pulsed X-ray beams, and tests in real conditions on site in different European hospitals were performed. This study highlights
the limitations of APDs for this application and the need of improving the APD technology so as to fulfil all needs in the
IR/IC field.
