WP2: Development of practical eye lens dosimetry in interventional radiology

Coordinator:
ENEA Radiation Protection Institute Bologna

Participants:
ENEA, RADCARD, GAEC, CEA, NIOM, SCK

Specific objectives:

Development of a formalism to measure eye lens doses (via the theoretical study of the operational quantity Hp(3) for the eye lens and its practical implementation)
Design and development of new practical dosemeters that are suitable to respond in terms of Hp(3) (measurement of eye lens dose)

Activities:

To critically study the definition and to numerically evaluate the quantity Hp(3). A complete set of energy and angular dependent conversion coefficients will be provided
To develop a thermoluminescence based dosemeter suitable for readout and handling equipment commonly available in existing European dosimetric services. The dosemeter development will include a sequence of the following sub-tasks:
Design of several alternative dosemeter models supported by Monte Carlo modelling
Manufacture of pre-prototype working models of dosemeters
Measurements in laboratory and workplace conditions
Production of prototypes of the dosemeters
Using the calculated conversion coefficients from air kerma to HT(lens) and the design of a simplified calibration phantom, a calibration facility will be developed
Type-testing of prototype dosemeters
