چکیده

Bhabha Atomic Research Centre, Mumbai, India designed and developed a telecobalt unit, which was named as Bhabhatron-II. In this paper, the results pertaining to radiation safety of indigenously developed Bhabhatron-II telecobalt unit are reported. The various tests were carried out as per requirements of International Electrotechnical Commission standard and acceptance criteria developed nationally. Various devices such as CaSO4: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 IEC-60601-2-11 standard except the collimator transmission through X collimators (upper jaw), which marginally exceeds the tolerance limit.

Development of Indigenous Source of Cobalt Suitable for Radiation Technology Applications

The role of Cobalt-60 as a radiation source in teletherapy for the treatment of cancer needs hardly to be reiterated. Although not used commonly in developed countries, cobalt-60 teletherapy machines can still be regarded as a very viable and cost effective option for the treatment of a sizeable fraction of cancer patients. At present in India, there are only 399 teletherapy units (280 telecoba...

Is your current safety system compliant to today's safety standard?

It is estimated that about 66% of the Programmable Electronic Systems (PES) running in the process industry were installed before the publication of today’s commonly used safety standards (IEC 61508 and IEC 61511/ISA 84) Some of those safety systems, particularly the ones installed between the late 1980's and early 2000, are either 1. General-purpose PLCs, 2. Not designed or certified according...

Design, implementation and validation of a motorized wedge filter for a telecobalt machine (Bhabhatron-II).

A universal wedge filter of 15W × 20 cm(2) and 60° nominal wedge angle is designed and placed between the collimating jaws and penumbra trimmers inside the treatment head. A pneumatically driven actuating mechanism toggles the wedge between the wedge IN position and wedge OUT position. The effective wedge angles were determined using an analytical formula. An accumulated wedge profile at a dept...
