Covers MEDICAL ELECTRON ACCELERATORS used for therapy purposes in human medical practice. Applies to ELECTRON ACCELERATORS which deliver a RADIATION BEAM of either X or ELECTRON RADIATION with ENERGIES in the range 1 MeV to 50 MeV at maximum ABSORBED DOSE RATES between 0,001 Gy s to the power of minus 1 and 1 Gy s to the power of minus 1 at 1m from the RADIATION SOURCE and at NORMAL TREATMENT DISTANCES between 50 cm and 200 cm from the RADIATION SOURCE. Describes test procedures to be undertaken by the manufacturer at design and construction stage but does not specify acceptance tests to be performed after installation on site.
