John Dunn, MD, JD: The historical basis for the no threshold claims in matters of radiation biophysics was not scientifically valid and a thorough investigation by Dr. Calabrese creates a serious question of ideology driving scientific claims rather than good evidence and reliable science. The idea that radiation or any other toxin or harmful substance has no threshold for effect as a cause of cancer ignores the evidence. The widespread acceptance of linear no threshold toxicity/oncology has created a risk management protocol that is irrational and unscientific. It does not serve the public well.
