Radiotherapy is modality of medical treatment using ionising radiation such as gamma rays (emitted from radioactive source), high energy X-rays (generated by medical accelerator) and particle therapy using Hadron Therapy Accelerator (e.g. Proton/ Carbon Ion based).  In radiotherapy, aim is to deliver intended radiation dose to the tumour and minimum possible dose to the surrounding normal tissue. The radiation dose is delivered to the tumour either by external beam therapy (i.e. teletherapy) or brachytherapy or in combination of both depending on necessity of the case. In the external beam radiation therapy, the radiation dose is delivered to the tumour from a teletherapy unit where radiation source is kept at a certain distance from the tumour. Brachytherapy is a method of cancer treatment in which radiation sources are kept at a short distance from the tumour to deliver radiation dose by interstitial, intracavitary or surface application.

 

To establish a Radiotherapy facility, the user institute must go through the Regulatory requirements as mentioned in the Atomic Energy (Radiation Protection) Rules, 2004 and AERB Safety Codes [AERB/RF-SC/MED-1(Rev.1)] and shall obtain requisite regulatory consent from AERB as per AERB Safety Guide for Consenting process for Radiation Facilities (AERB/SG/G-3).
