Eye lens dosimetry: Task 2 within the ORAMED project

The ORAMED (Optimization of Radiation protection for Medical staff) project is funded by EU-EURATOM within the 7. Framework Programme. Task 2 of the project is devoted to study the dose to the eye lens. The study was subdivided into various topics, starting from a critical revision of the operational quantity Hp(3), with the corresponding proposal of a cylindrical phantom simulating as best as possible the head in which the eyes are located, the production of a complete set of air kerma to dose equivalent conversion coefficients for photons from 10 keV to 10 MeV, and finally, the optimisation of the design of a personal dosemeter well suited to respond in terms of Hp(3). The paper presents some preliminary results. (authors)
