3.13.1.6 Lead Time <strong>for</strong> Submission/Availability of Documents<br />
The lead time <strong>for</strong> submission of documents at any stage of consenting process<br />
is 30 days be<strong>for</strong>e the desired date of consent provided the application is<br />
complete in all respects <strong>for</strong> review by AERB.<br />
3.13.2 Medical Diagnostic X-ray Equipment<br />
3.13.2.1 General<br />
The most common and reliable diagnostic technique in use today is X-ray<br />
imaging. In India more than 50,000 X-ray machines are currently in use. The<br />
types of X-ray radiography machines vary from simple mobile X-ray units<br />
(ranging from 40 kVp to 100 kVp with 20 mA to 100 mA) to larger stationary<br />
X-ray units (ranging from 100 kVp to 150 kVp with 100 mA to 800 mA).<br />
Radiography is sometimes combined with fluoroscopy (conventional/IIT/<br />
digital). Special machines are capable of dental radiography, ortho-pantomograph<br />
(OPG), bone densitomet and mammography. Simulator is another<br />
X-ray unit used <strong>for</strong> the verification of the therapy technique prior to start of<br />
the external beam therapy in radiotherapy.<br />
3.13.2.2 Site and Layout Plan Approval<br />
The room housing fixed radiography/fluoroscopy units, should be planned<br />
in accordance with the radiation safety requirements stipulated by AERB in<br />
Safety Code <strong>for</strong> ‘Medical Diagnostic X-ray Equipment and Installations’,<br />
[AERB/SC/MED-2(Rev.1), 2001]. These are essential in the nature of access<br />
control, patient flow control and radiation shielding. Adequate distance from<br />
the X-ray unit to walls and ceiling obviates the need <strong>for</strong> unnecessary shielding<br />
and lead lining. Conventional fluoroscopy rooms require proper darkening<br />
so that illumination on the screen is possible with minimal beam current and<br />
hence minimal patient dose. The <strong>for</strong>mat of Application <strong>for</strong> Site and Layout<br />
plan approval of diagnostic X-ray installation is given in Annexure 39.<br />
3.13.2.3 Construction:<br />
The construction of the diagnostic X-ray facility can be started after obtaining<br />
layout plan approval from regulatory board and no separate regulatory<br />
clearance is required <strong>for</strong> construction.<br />
3.13.2.4 Procurement:<br />
It is to be ensured that only AERB Type Approved diagnostic X-ray units<br />
should be installed and used <strong>for</strong> patient diagnosis in India. In case unit is not<br />
Type Approved, supplier/manufacturer has to submit application <strong>for</strong> Type<br />
Approval along with relevant documents to AERB <strong>for</strong> issuing Type Approval<br />
as referred in subsection 3.18.1.<br />
