A new system of setting National DRLs for diagnostic radiology procedures has been launched with new values replacing those set by the Department of Health over a decade ago.
"The NDRLs will be regularly reviewed and updated by Public Health England (PHE), in collaboration with a working party on national dose surveys and DRLs with representation from PHE, the radiology professional bodies and the Department of Health. Data for future NDRLs will be considered from national dose surveys undertaken by PHE and from other appropriate studies."
For further details, and the latest NDRL values, please visit the PHE website.
Diagnostic Reference Levels are defined in UK legislation (IRMER) as "dose levels in medical radiodiagnostic practices or, in the case of radioactive medicinal products, levels of activity, for typical examinations for groups of standard-sized patients or standard phantoms for broadly defined types of equipment", and from 2018 will also include "interventional radiology practices". They are not intended to be compared with doses to individual patients, but to the average dose to a sample of patients (e.g. 20 patients undergoing a particular examination using a particular X-ray set).
The UK’s Health Protection Agency has issued a warning concerning the Tianjie Dental ‘Falcon’ hand held X-ray set imported from China. This device is not CE marked and could lead to large radiation doses to staff and patients. Click for full report.
Cone Beam CT (CBCT) is a relatively new technique, not covered by the NRPB’s 2001 Guidance Notes. In some cases, CBCT can lead to considerably larger radiation doses to staff and patients if used without proper precautions.
The UK’s Health Protection Agency has issued free guidance on the safe use of dental CBCT, available to download from www.hpa.org.uk.
We are pleased to announce that Dr Tim Wood has been awarded the RPA2000 Certificate of Competence to be a Radiation Protection Adviser. Such a certificate from a body authorised by the HSE is required by any person acting as a Radiation Protection Adviser under the Ionising Radiations Regulations 1999. There regulations require an employer to consult a certificated RPA on;
Tim joins our other certificated RPAs, John Saunderson and Craig Moore. Tim has also been appointed, alongside John and Craig, as a Medical Physics Expert (MPE) under the Ionising Radiation (Medical Exposure) Regulations 2000 (IRMER) for radiological imaging.
