It is no secret that the enthusiastic use of X-rays and radioactive materials in the early years following their discovery led to numerous biological adverse effects. Realisation of this cause-effect relationship sparked a keen interest in protection against the hazards associated with medical radiation exposure.
The recent dramatic increase in the number of diagnostic medical procedures that use ionising radiation, including nuclear medicine procedures, has resulted in a very significant increase in cumulative exposure to radiation and in the small, but measurable, related risk of carcinogenesis.
In 1980, medical imaging was estimated to account for 15% of the average annual radiation exposure received by the population of the USA (0.54 of 3.6 mSv); by 2006 this proportion had risen to 50% (3.0 of 6.0 mSv). To explore this trend, Mettler and co-workers  recently reviewed two publicly available surveys of radiological and...
