AERB License for Dental X-Ray Machines: A Practical Guide for Indian Clinics

KlyientAI · India · Updated 2026-10-18

Every dental clinic in India running an intraoral, OPG, or CBCT X-ray machine needs clearance from the Atomic Energy Regulatory Board (AERB). This is not optional paperwork. Operating an unregistered X-ray unit is a regulatory violation, and increasingly, state clinical establishment registrations and NABH assessments ask for proof of valid AERB licensing before approval.

What AERB actually regulates

AERB licenses the radiation-generating equipment in your clinic, not the clinic itself. Each X-ray unit (intraoral, OPG, CBCT) needs its own registration on AERB's e-LORA portal (elora.aerb.gov.in). If you add a second OPG machine or replace an old unit, that is a fresh application, not an update to the existing one.

Documents you need before applying

• Type Approval Certificate (TAC) of the X-ray machine, issued by AERB to the manufacturer or supplier
• Room layout plan showing machine position, operator standing area, and shielding (lead-lined walls, doors, windows)
• Shielding design report if the room was not pre-certified by the equipment vendor
• Proof of clinic premises ownership or lease agreement
• Qualification and training certificates of the proposed Radiation Safety Officer
• Invoice and installation report from the equipment supplier
• Quality Assurance (QA) test report of the machine, usually done at installation

Most reputable dental X-ray vendors in India (Dentsply, Planmeca, Carestream dealers) provide the shielding layout and TAC as part of the installation package. Ask for these in writing before you make the final payment, not after.

The Radiation Safety Officer (RSO) requirement

Every licensed facility must name an RSO responsible for radiation safety compliance. For intraoral units, the treating dentist can usually qualify as RSO after completing the AERB-recognised online RSO training and passing the certification exam. OPG and CBCT units sometimes require a higher RSO certification level depending on machine output, so check the category listed on your TAC before assuming the same person qualifies.

The RSO's responsibilities include maintaining a radiation safety logbook, ensuring staff wear personal dosimetry badges (TLD/OSL badges, usually procured quarterly from an AERB-approved dosimetry lab), and being the point of contact during inspections.

Application process on e-LORA

1. Create a facility profile on e-LORA with clinic PAN, address, and ownership proof
2. Upload machine-specific TAC, layout, and RSO details
3. Pay the prescribed registration fee online
4. Receive provisional registration number, which allows you to start using the machine
5. Submit the QA test report within the stipulated period to move to full registration

Typical timelines

Preparing for an AERB inspection

AERB or its designated inspecting authority may visit for post-licensing verification. Clinics that fail inspections usually lose points on basic housekeeping, not technical faults. Before any visit, check that:

• Warning signage ("Caution: X-ray in use") is displayed outside the X-ray room
• Lead apron and thyroid shield are available and not cracked or torn
• Dosimetry badges are current, not expired, and worn by staff operating the machine
• The radiation safety logbook is updated with QA and maintenance entries
• The RSO certificate and registration number are displayed or readily available

Renewal: do not wait for the reminder email

AERB licenses for dental X-ray machines are typically valid for 5 years. Start the renewal process at least 3 months before expiry, since a fresh QA test report and sometimes a shielding re-verification may be required, especially if the room has been renovated or the machine relocated. Clinics that let the license lapse often find out only when a patient's insurance TPA or an NABH auditor asks for the certificate.

Rules and portal processes are updated periodically by AERB, so always cross-check the current requirements on elora.aerb.gov.in or with your equipment vendor before applying, rather than relying solely on what worked for a colleague's clinic last year.
