Radiological protection — Medical proton accelerators — Requirements and recommendations for shielding design and evaluation

Scope

This International Standard is applicable to radiation shielding design and evaluation work for medical proton accelerators with nominal energies of the beam ranging from 70 MeV to 250 MeV, with subsystem such as beamlines, energy selection system (for cyclotron) and nozzle components.
The radiation protection requirements and recommendations given in this international standard cover the aspects relating to regulations, shielding design goals and other design criteria, role of the manufacturers, of the radiation protection officer or qualified expert and interactions between stakeholders, source terms and radiations around a proton accelerator, shielding for accelerators and its subsystems (including shielding materials and transmission values, calculations for various room configurations, duct impact on radiation protection), the radiological monitoring (measurements) and area control.
