Radiation Doses

To follow on from the radiation dosage questionnaire data I presented at grand round the other week, here’s something from today’s e-news suggesting how many extra cancers are caused each year due to excessive CT scanning.

As always, there’s a question on the actual equivalence of dose for a CXR, and a CT.  Our data here has a CXR as 0.02 mSv, about 3 days background radiation in the UK.  To give an idea of lethality, Dr Slotin (The original Mr Manhattan) received a dose of 21 Sv, and died 9 days later.  That’s a million CXRs in a single dose.

Still, I think we massively underestimate the impact of ionising radiation on our young (and old) patients.
