REFERENCE DOSIMETRY STUDY FOR 3 MEV ELECTRON-BEAM ACCELERATOR IN MALAYSIA

An effective quality assurance programme is initiated for the use of t he electron beam with energies up to 3 MeV. The key element of the pro gramme is the establishment of a relationship between the standardised beam to the routine technique which is employed to verify the beam pa rameter. A total absorbing calorimeter was adopted as a suitable refer ence system and when used in combination with the electron current den sitymeter (ECD) will enable to determine the mean energy for electron with energies between 1 to 3 MeV. An appropriate method of transfering the standard parameter is studied and the work that is expected to op timise the accuracy attainable with routine check-up of the irradiatio n parameter are presented.
