There are 90 medical institutions in the country in which advice on planning of teletherapy installations has been rendered by the Division of Radiological Protection in the last 5 years. In initial periods many hospitals had caesium-137 and other fixed beam cobalt-60 units such as Eldorado-8, incorporating source strengths upto 3000 ci. These plans were supplied by AECL or other suppliers of the units and they were modified by DRP to suit Indian conditions. Later on, the use of Rotational Teletherapy units such as Theratron-60, Gammatron-R, Theratron-780 and Picker C-8 units came into prominent use. A standard plan which may normally accommodate either of these units upto a maximum source strength for 12000 Ci was designed, which had to be slightly notified in individual cases, depending upon the availability of area and the nature of occupancy all around and other factors such as cast and economy. The paper reviews the sequence of the development in the design of the plans of teletherapy units installed in this country up till now. It also brings out the modifications carried out in the plan supplied by the supplier of the units. This presentation will show how the institutions can acceptable to the competent authority.
