- •Estimates were made of number of patients likely receiving cumulative effective dose ≥100 mSv in 5-years from CT exams.
- •It results in about 2.5 million patients in 35 OECD countries.
- •Countries were classified into Low: 0 to <1, Medium: 1 to <2 and High: ≥2 patients with CED ≥ 100 mSv/1000 population.
- •There are 2 countries in Low, 24 in medium and 9 in high number group.
- •Stake holders in patient radiation safety should attend to the issue of high doses to such large number of patients.
