Optical radiation

Optical radiation is used in healthcare to treat a wide variety of conditions including neonatal jaundice, psoriasis and skin cancers and to perform laser surgery.

The team of clinical scientists, medical physicists and clinical technologists at CMPE provide advice and clinical support to departments working with these technologies to ensure that patients are treated effectively and the risks to staff are minimised.  Our principal clinical areas of work are:

  • Safety advice for laser and Intense pulsed light (IPL) sources
  • Clinical support and safety advice for ultraviolet phototherapy and photodynamic therapy

Hospitals may use sources of optical radiation for illumination, diagnosis, therapy, research and development and non-clinical applications, e.g. theatre lighting, laser imaging, and sterilisation. We can advise on these devices also. We can provide detailed safety assessments for the optical hazards of these and other intense light sources as covered by the Control of Artificial Optical Radiation (AOR) Regulations (2010).

This service covers the following areas of expertise:

  • Safety advice for the use of lasers, UV treatment systems, and other equipment that produces hazardous levels of optical radiation
  • Detailed optical hazard assessments of intense light sources for the purposes of compliance with exposure limits.
  • Equipment performance and calibration testing of UV treatment units.
  • Assistance with establishing quality assurance programmes


The group is active in research and development in a number of non-ionising radiation topics and also provides support for clinical research projects utilising non-ionising radiation.

  • Laser/IPL and optical radiation safety training for clinical users and laser protection supervisors
  • Safety awareness for users of broadband radiation sources such as UV and  PDT sources
  • Work-based training for the Modernising Scientific Careers Scientist Training Programme.
  • Safety training for those using or maintaining artificial optical radiation sources, which can be tailored to suit a particular user group.

Staff actively participate in a range of professional matters ranging from refereeing scientific papers, presenting and attending at national and international conferences to providing advice to national and international bodies.

  • We have many years of experience in providing LPA services NHS trusts and private hospitals ensuring that sources of non-ionising radiation are used safely.
  • The group operates within a BS EN ISO 9001:2008 quality system.
