Regulation 11(1) of the Ionising Radiations Regulations 2017 (IRR17), Ionising Radiations Regulations (Northern Ireland) 2017 (IRR(NI)17)states that x-ray equipment "be properly maintained so that it remains fit for the purpose for which it was intended" and "be adequately tested and examined at appropriate intervals.

Calendar Orange How often do I need my X-Ray equipment inspecting?

The majority of manufacturers recommend you have an annual electro-mechanical inspection.

For radiological checks, a test should be undertaken at least once every three years for intra-oral, panoramic and panoramic/cephalometric x-ray sets; annually for CBCT and hand-held dental x-ray sets. You may find, however, that it is more convenient for you to have us carry out this type of testing along with the annual electro-mechanical test.

Clock Orange How long will an X-Ray inspection take?

Our inspection usually takes 45 minutes for an intra-oral X-Ray set and an hour and a half for a panoramic X-Ray set.

Pound Orange How much do you charge?

Electrical Mechanical Check for intra-oral, OPG (without Ceph) and handheld x-ray equipment, the price of an inspection is £123+vat for members and £141+vat for non-members.

Routine Test for intra-oral, OPG (without Ceph) and handheld x-ray equipment, the price of an inspection is £158+vat for members and £181+vat for non-members.


Person Orange What will our engineer actually do during the inspection?


  • Ensure the x-ray set is switched off

  • Review the paperwork from the previous visit(s) and make a note of any concerns noted which have not been addressed. If they have not been addressed, ensure they are noted and brought to your attention before the test continues

  • Check serial number of the x-ray tube head

  • Mark down the operating potential [kV], tube current [mA] and filtration values from the tube head

  • Check the stability of the x-ray mount

  • Check for any damage to the x-ray tubehead

  • Check the electrical and mechanical safety of the machine and grade its condition

  • Check the condition of the x-ray exposure control

  • In the case of an intra-oral x-ray set, check the condition and operation of the counter-balanced arm and fittings

  • In the case of a panoramic/CBCT x-ray set, check the rotational movement of the x-ray tubehead and the fittings

  • In the case of a cephalometric x-ray set, check the scanning motion of the image receptor with the x-ray tubehead and, where applicable, the secondary collimator.

  • Switch on the x-ray set

  • Check the operation of the dead man switch and/or emergency stops

  • Check the operation of the equipment warning lights and audible signals

  • For the routine (three-yearly) performance testing, complete the required number of exposures and record the measurement results (patient entrance dose [mGy], kV, exposure time, filtration)

  • Check the consistency of the radiation output

  • Complete ‘Radiological Inspection’ documentation, accurately completing all relevant fields

  • Photograph the x-ray equipment as a record of any concerns noted on your paperwork

  • Highlight any discrepancies to you in relation to the electro-mechanical operation of the x-ray equipment

  • Ensure that the exposure settings are as found on arrival

  • Switch the x-ray set off

  • If you have membership and/or have Radiation Protection Consultancy contract, the results will be sent to DD's RPA/MPE for review and, for the routine performance testing, a brief formal report will then be issued to the practice.
