WP3: Optimisation of the use of active personal dosemeters in interventional radiology

Coordinator:
Institute for Radiological Protection and Nuclear Safety

Participants:
IRSN, MGPI, CEA, SCK, UPC, CHUV

Specific objectives:

  • To optimise the use of active personal dosemeters (APDs) in interventional radiology

Activities:

  • To make a selection of APDs according to the previous results of the CONRAD (ref. 1,2) and IAEA-EURADOS groups (ref. 3)
  • To study the real radiation field characteristics encountered in interventional radiology in terms of energy, angular distribution, dose rate and pulse characteristics
  • To define, by measurements under laboratory conditions, the angular and dose rate response of APDs. Tests will be performed using the reference photon facilities of laboratories which participate in this work package
  • To study the effect of the frequency and duration of pulses on the APD response by testing dosemeters in real conditions on site in different hospitals and under laboratory conditions
  • To prepare guidelines related to the use of APDs in interventional radiology, to define corrections that will eventually be applied
  • To propose technical solutions to improve the response of APDs in collaboration with the manufacturer MGPI
  • To test the different technical solutions (with continuous feedback) developed by MGPI under laboratory conditions and on site in hospitals
