Why small clinics get caught out
A large hospital has a medical physicist, a radiation safety committee and a compliance department. A clinic with one dental unit has a dentist, a nurse and a receptionist — and exactly the same regulatory obligations for that unit. The rules do not scale down with the practice.
The good news is that the list is short and finite. Most clinics that fail an inspection fail on paperwork and on a missing responsible person, not on anything dangerous.
The checklist
What a clinic needs in place
| Item | What it means in a small practice |
|---|---|
| A valid facility licence | Issued for the premises and covering each X-ray unit by make, model and serial number — including a unit that replaced another. |
| A named responsible person | Appointed in writing and trained in radiation protection. In a small clinic this is usually a practising clinician, not a separate post. |
| An assessed room | A shielding assessment for the room as built and as used, covering the walls, the door, the control position and the rooms above and below. |
| Personal dosimeters | For everyone who operates the unit or stays in the room during exposures, exchanged and read on a fixed cycle. |
| Equipment testing | Acceptance testing when a unit is installed and periodic performance testing afterwards, with the reports kept. |
| Protective equipment | Aprons and thyroid collars in serviceable condition, checked for cracks and stored hanging rather than folded. |
| Signage and control | Warning signs at the room entrance, and a control position from which the operator is protected and can see the door. |
| Records | Licence, appointment letter, training certificates, dose reports, equipment test reports and maintenance records, in one place someone can produce on request. |
What is different about dental
Dental practices are treated as low-risk in general, and intraoral units genuinely are — the beam is small, the output is low and the exposure is brief. That reputation, however, is what causes two specific problems.
- Panoramic and cone beam CT units are not intraoral units. A CBCT delivers a far higher patient dose and needs a room assessment, justification for each examination and operator training that matches the technology.
- Nobody holds the film or the sensor for the patient. If a patient cannot hold it, a holder is used, and if a person must assist, it is an accompanying adult with protection — never a member of staff, and never the same person repeatedly.
- The operator stands behind the protective barrier or at the distance stated for the unit, and not in the doorway with a hand holding the door.
The findings inspectors write most often
Frequently asked questions
Does a one-unit clinic really need a responsible person?
Yes — someone has to be accountable for the licence conditions, the records and the staff. In a small practice this is a role a working clinician takes on after training, not a full-time appointment, but it must be named in writing rather than assumed.
We are moving to a new premises. What moves with us?
The equipment moves; the authorisation does not. The new room needs its own shielding assessment and the licence has to reflect the new address before the unit is used there. Clinics that install first and notify later usually end up doing the work twice.
Is a pregnant staff member allowed to keep working?
Normally yes, once the pregnancy is declared and the working conditions are reviewed so that the dose to the embryo or fetus is kept very low for the rest of the pregnancy. The declaration route should exist in writing before anyone needs it.
How long do we keep the records?
Dose records are long-term records kept well beyond the end of employment. Equipment, training and maintenance records are kept for the periods set in the licence conditions, and in practice the simplest rule for a small clinic is to keep everything in one file and dispose of nothing.
Training and consulting
ALDuha Institute for Training and Environmental Consulting trains responsible persons and clinical staff in Qatar, prepares room shielding assessments and licensing files for clinics, and reviews an existing practice against this checklist before an inspection rather than after one.
