The risk for causing a radiation-induced cancer is not directly measurable in patients subjected to a radiation dose below 0.1 Sv in diagnostic radiology because the doses are too low and the statistical noise in epidemiological studies is too high to directly attribute any specific cancer cases to such low doses. In contrast, Chernobyl accident victims and atomic bomb survivors were exposed to much higher doses, making it possible to measure and study the effects directly.
