IRMER Radiation Physics and Biology


About this course

Dental staff in the UK are required by law to be "IRMER Trained". This law applies to everyone involved in taking and/or processing radiographs, not just GDC registrants. This course covers the physics of X-rays, and the types of damage they can cause to biological systems, knowledge required by The Ionising Radiation (Medical Exposure) Regulations 2017.

This course is a GDC Highly Recommended CPD Topic (Radiography and radiation protection).

This course is relevant to the whole dental team.

This course provides training for the roles of Operator, Practitioner, Referrer, Legal Person, and Radiation Protection Advisor.

CPD Time: 2 hours (2 CE Credits)

Customer feedback on this course

  • Very good, detailed explanations and truly enjoyed the course.
  • So informative and understandable.
  • Great course. I really appreciated the video clips.
  • Very nicely presented and interesting, easy to understand.
  • Great module on IRMER Radiation Physics and Biology, excellent content.

Assessment: 12 MCQs. Pass mark 75%. more…

On passing the assessment you will immediately receive a GDC-recognised Enhanced CPD IRMER Certificate.

Access: You will have access for 12 months, and can take the course as often as you wish in this period.

The aim of the learning and teaching materials in this course is to allow learners to develop their professional knowledge, understanding and competence in Radiation Physics and Biology, as it applies to Radiography and Radiation Protection, in line with their identified personal development requirements.

Course objective
• to teach the core of scientific knowledge and the understanding necessary to use X-ray equipment and process radiographs competently and safely in dental practice, in line with the theoretical knowledge requirements of the IRR and IR(ME)R laws and current professional recommendations.

Anticipated learning outcomes:
The learner will:
• have an understanding of the physical principles involved in x-ray generation
• have an understanding of the biological effects and dangers of x-ray radiation
• learn how to minimise these risks in dental radiography and radiology
• through achieving these outcomes, provide an improved level of service to their patients.
