Added text to state that one approach to estimate the potential contribution of exposure to ionizing radiation from medical imaging is to develop statistical models based on the estimated cancer risks associated with a range of dose levels.
Added text about a cohort of 10.9 million electronic medical records of Australians who received diagnostic computed tomography (CT) scans when they were aged 0 to 19 years; those who had at least one CT scan were statistically significantly more likely to be diagnosed with cancer as they were followed into young adulthood, compared with those who did not have a CT scan (cited Mathews et al. as reference 12).
