[3] Green and Peter Karamoskos (a nuclear radiologist) say there is growing scientific confidence in the linear no-threshold model for ionising radiation.

"[5] Balanced against this view is the benefit to tens of thousand of people in having the medical conditions correctly diagnosed and treated, often saving their lives, and the highly successful treatment of serious conditions such as cancer.

[citation needed] According to Green and Karamoskos, the alternative view, that low-level radiation is harmless, is limited to a small number of scientists "whose voice is greatly amplified by the nuclear industry".

In Australia, for example, Green believes uranium mining and exploration companies have sponsored speaking tours by scientists who claim that low level radiation exposure is not only harmless but actually good for you.
