Abstract:
:The Italian National Centre for Oncological Hadrontherapy is currently under construction in Pavia. It is designed for the treatment of deep-seated tumours (up to a depth of 27 cm of water equivalent) with proton and C-ion beams as well as for both clinical and radiobiological research. The particles will be accelerated by a 7-MeV u(-1) LINAC injector and a 400-MeV u(-1) synchrotron. In the first phase of the project, three treatment rooms will be in operation, equipped with four fixed beams, three horizontal and one vertical. The accelerators are currently undergoing commissioning. The main radiation protection problems encountered (shielding, activation, etc.) are hereby illustrated and discussed in relation to the constraints set by the Italian national authorities.
