In late June the Nuclear Regulatory Commission (NRC) announced that three petitioners, a radiation-health organization, a health physicist, and a professor of radiation oncology at the University of California, Los Angeles, asked that it amend its radiation protection standards to change the basis of those regulations from the linear-no-threshold (LNT) model to the hormesis model. The NRC explained, “The radiation hormesis model provides that exposure of the human body to low levels of ionizing radiation is beneficial and protects the human body against deleterious effects of high levels of radiation.” (1)
