TLD personnel radiation monitoring at VECC, Kolkata

A cyclotron guides the nuclei of atom magnetically into a beam and using RF accelerates them electrically into a target, where they smash into other nuclei to produce newly formed isotopes and reveal the basic building blocks of matter, The cyclotron operates at relatively high beam currents results in dose rates in the vaults of up to 30 Gy / hr. and there is therefore the risk of acute exposure of personnel. The following article describes how the TLD PMS Unit, Personnel Monitoring Section, Radiological Physics and Advisory Division, Bhabha Atomic Research Centre at Variable Energy Cyclotron Centre, Kolkata is looking after the external radiation monitoring of the personnel at VECC, Kolkata since its inception and that for the state of West Bengal and Uranium Mining and Milling workers as well.
