The 2nd edition of ‘Guidance Notes for Dental Practitioners on the Safe Use of X-ray Equipment’ is now available.  Originally published in 2001, the Dental GNs set down principles of good practice with the aim of restricting doses to all involved as far as reasonably practicable, as required by UK radiation protection legislation.  SRP was represented on the working party (led by PHE) that generated the revised Dental GNs and included representatives from all the UK regulatory bodies, experts from professional and advisory bodies, consultant dental radiologists and general dental practice.  Adherence to the guidance should materially contribute to and support high standards of radiation protection throughout the UK dental profession.
