Background/Introduction
Normal 0 false false false EL X-NONE X-NONE MicrosoftInternetExplorer4
Scientific literature shows the existence of large variation of patient radiation doses in diagnostic and interventional X-ray examinations mainly due to differences in examination protocols.
However,
there are radiation incidents involving the exposure of a patient to a dose much greater than intended.
Main reasons for these very high doses are a) lack of knowledge in medical radiation protection,
b) poor equipment knowledge and c) use of inappropriate protocols.
There are also other causes of accidental...

There are data on radiological incidents/accidents in the literature.
A recent review paper provides information on radiation overexposure accidents worldwide (1).
A well known accident occurred in 2009,
when more than 250 patients in the USA received overdoses from brain perfusion CT.
In some patients,
deterministic effects (skin injuries and hair loss) were observed after the exposure.
However,
there are also radiation incidents where radiation doses are not high enough to produce deterministic effects.
In these...
Conclusion and Recommendations
Normal 0 false false false EL X-NONE X-NONE MicrosoftInternetExplorer4
Accidental medical exposures are a source of continuing concern.
Article 63 of the new European Union Basic Safety Standards (2) is focused on accidental and unintended exposures.
This article states that all European Member States shall ensure that all reasonable measures are taken to minimise the probability and magnitude of accidental or unintended exposures of individuals subject to medical exposure.

The European Federation of Organisations for Medical Physics (EFOMP) was founded in May 1980 in London to serve as an umbrella organisation for national medical physics organizationss.
The current membership covers European organisations which together represent more than 7500 medical physicists and clinical engineers working in the field of medical physics.
