However, severe problems seem to exist with their data, including the fact that one study they cite (Muirhead 2009) contradicts their conclusion. Their study also relied on experiments with mice, while the epidemiological studies in the Bulletin of the Atomic Scientists' Radiation Issue relied on humans, and a great many more of them.
