Sustainability of medical imaging

Contemporary medicine relies heavily on radiological and mediconuclear investigations and procedures. However, the often essential information derived from such investigations is obtained at a risk that few doctors are fully aware of. Increased awareness among both doctors and patients would help reduce the number of inappropriate examinations and the avoidable biological burden on current and future generations. In this article, I outline the effect of ionising testing in our society, review the possible detrimental public health effect based on current estimates of risk, and discuss simple ways of achieving a more cautious approach.
