Bhabha Atomic Research Centre, Mumbai, India designed and developed a telecobalt unit, Bhabhatron-II. In this paper, the results pertaining to radiation safety of the indigenously developed Bhabhatron-II telecobalt unit are reported. The various tests were carried out as per requirements of International Electrotechnical Commission standards and acceptance criteria. Various devices such as CaS0₄:Dy-based thermoluminescent dosimeters, Farmer-type ionization chamber, water phantom, and radiographic films were used. All the parameters pertaining to radiation leakage/transmission were within the tolerance limits, as per the IEC standard 60601-2-11, except the collimator transmission through X collimators (upper jaw), which marginally exceeds the tolerance limit.
