Are There Radiation Dose Limits For Patients?
While there are no specified dose limits for patients, there is a responsibility to ensure that all exposures are justified and optimised, as stated in regulations 7.1 and 7.5 (a) of S.I. 478 of 2002. All exposures must have a net benefit, and must be kept as low as reasonably achievable consistent with obtaining the required diagnostic information.
The Dental and Medical Councils are also required to promote the establishment and use of diagnostic reference levels (DRLs). These are dose levels which are not expected to be exceeded for standard procedures when good and normal practice regarding diagnostic and technical performance is applied. The Medical Council position paper can be found here and the Dental Council document here.
