Our past experience shows that about 10-15 institutions approach this Division for Planning of new radiation therapy installation in a year. Normally a model layout giving a general idea about the area required and the approximate wall thicknesses is sent to these institutions. Based on this and their requirement the institution sends us an architectural drawing of the proposed installation. This plan is then carefully scrutinized from radiation safety stand point which involves lot of calculations. In most of the cases these plans have again to be modified taking into account the parameters such as the orientation of the unit, occupancies around the installation etc. A modified plan may not always be acceptable to the user due to architectural reasons, change of site etc. Thus the whole process is to be repeated at least two to three times which involves lot of time. To circumvent this difficulty computer package has been prepared which gives many possible plans of the installations for a given site out of which the most suitable one from the user's point of view can be selected. Some of the Salient features of this program are that a complete mapping of the exposure levels around the installation, amount of construction material like concrete needed will also be given. This will help in preparing a rough estimate of the cost of construction of the building.
