Re: Cancer risk in 680 000 people exposed to computed tomography scans in childhood or adolescence: data linkage study of 11 million Australians
In Greece, CT scanners, CT exams, and relative radiation exposures appear in massive numbers. 
Up to 40% of patients admitted in public hospitals every year will be sent for CT scans!
32% of the whole Greek population receives a CT scan every year! 
Corruption, favourable NHS reimbursements, together with medical incompetence, are the reasons for this Radiation Exposure World Record.
Researchers interested in CT scan radiation exposure hazards should come in Greece in order to study the Greek population.
