Risk from radiation is a slope, there is no one “cut-off” point below which it is “perfectly safe” – even small radiation doses may have some risk. Therefore, statutory regulations require the dose to be “as low as reasonably achievable”.
Having said that, there is no absolute “legal” limit to the dose a patient can receive – go ahead and order the scan if you think the investigation is medically indicated, and the benefits outweigh the risk.
What then, is the risk, and how do you explain it to patients in layman terms?
