CT Scan Regulatory Framework in India

Computed Tomography (CT) involves higher radiation exposure compared to conventional radiography and is therefore subject to strict regulatory oversight in India. CT radiation safety and compliance are governed primarily by the Atomic Energy Regulatory Board (AERB) under the Atomic Energy Act, 1962, supported by national and international best-practice guidelines.

This section explains CT regulatory requirements from the perspectives of radiographers, institutions, radiation safety officers, and CT equipment operation, with an emphasis on radiation protection, dose optimisation, and legal compliance.

Students & Practicing Radiographers

Students posted in CT areas are classified as radiation workers
Must work under supervision
Personal dose monitoring is mandatory

Radiographers operating CT scanners are occupational radiation workers
Responsible for patient dose optimisation and radiation protection

Common Mistakes

Assuming students do not require monitoring
Poor awareness of occupational classification

Monitoring Devices Used in India

Thermoluminescent Dosimeter (TLD)
Optically Stimulated Luminescence (OSL) badge

Monitoring Authority

AERB-approved personnel monitoring agencies

Common Mistakes

Not wearing badges consistently
Wearing badges under lead aprons incorrectly
Delayed badge submission

Parameter	Limit
Effective dose	20 mSv/year (5-year average)
Lens of eye	20 mSv/year
Skin / extremities	500 mSv/year

Common Mistakes

Confusing patient dose with staff dose
Failure to report abnormal exposure

Examination justification
Protocol optimisation
Correct patient positioning
Pregnancy screening
Shielding where applicable

Common Mistakes

Using default protocols blindly
Poor communication with clinicians

Examination	Typical Dose
CT Head	1–2 mSv
CT Chest	5–7 mSv
CT Abdomen	8–10 mSv
CT Abdomen–Pelvis	10–15 mSv
CT Coronary Angiography	12–18 mSv
