核医学
Green and Peter Karamoskos (a nuclear radiologist) say there is growing scientific confidence in the linear no-threshold model for ionising radiation. The linear no-threshold model is used by Green to assert "Nuclear medicine is killing more people than the reactor and the isotope processing facility and everything else at Lucas Heights", adding "it is likely that of the people subjected to nuclear medicine in the year 2007 almost 500 will die from those nuclear medicine procedures at some time in the future." 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.
