X-ray Critical Examination

Dual-Tech Dental Service's qualified dental equipment engineers will help you meet your regulatory and legal requirements, taking care of the critical examination of x-ray equipment.




Critical Examination


A key requirement of both the Ionising Radiations Regulations 2017 (IRR17) and the Ionising Radiation (Medical Exposure) Regulations 2017 (IRMER17) is the need to seek expert advice. In the case of dental practices this will always be from external consultants. When opening a new practice, making alterations to the layout of a surgery or installing x-ray equipment, it is essential that a critical examination is carried out prior to first usage.

Where a person erects or installs an article for use at work, being work with ionising radiation, that person must – —

(a) undertake a critical examination of the way in which the article was erected or installed for the purpose of ensuring, in particular, that –
(i) any safety features and warning devices operate correctly; and (ii) there is sufficient protection for persons from exposure to ionising radiation;
(b) consult with the radiation protection adviser that they appointed, or that the employer engaged in work with ionising radiation appointed, with regard to the nature and extent of any critical examination and the results of that examination; and
(c) provide the employer engaged in work with ionising radiation with adequate information about proper use, testing and maintenance of the article.

Dual-Tech Dental Services' qualified engineers can carry out critical examinations as part of a new surgery build and fit-out, when supplying a new x-ray unit for use within your practice, or following any move or major maintenance procedure of an existing unit. If you are in any doubt as to whether you need a critical exam, get in touch - we will be happy to advise you.


When do I need a critical examination?

You will need to arrange for a critical examination to be undertaken if you install a new x-ray unit or replace an existing one, even if that unit has been used elsewhere in the practice or is second hand. In some cases a critical examination is required after major maintenance to an existing unit.
