Please help us raise money for a lawsuit to end the use of the linear no-threshold (LNT) model for radiation protection regulations.


FALLACY OF THE LNT MODEL. For several decades, regulatory agencies such as the Nuclear Regulatory Commission (NRC) have used the linear no-threshold (LNT) model for radiation protection regulations, based on the recommendations of advisory bodies such as the National Council on Radiation Protection & Measurements (NCRP). According to the LNT model, even the slightest increase in the radiation exposure would increase the risk of cancer. However, many studies of people exposed to low-dose radiation, such as the Nuclear Shipyard Workers Study, have shown reduced cancer mortality rates, directly contradicting the LNT model and supporting a phenomenon known as radiation hormesis, which is supported by experimental radiobiological data also. Such studies have been ignored by advisory bodies.


FEAR OF NUCLEAR ENERGY. Use of the LNT model has led to the widespread fear of the smallest amount of radiation exposure, causing considerable harm to the society. For example, the public fear of very low radiation exposures led the Japanese government to evacuate Fukushima residents following the damage to several nuclear reactors resulting from the tsunami in 2011, and these evacuations caused enormous economic harm and over 2000 deaths whereas no deaths were caused by radiation. In addition, fear of low-level radiation resulted in the complete shutdown of nuclear power in Japan, although it has proven to be the safest way of making electricity.


FEAR OF MEDICAL RADIATION. The concerns regarding low-dose radiation have also blocked and/or dissuaded the study of low-dose radiation for the prevention and treatment of many major diseases, including cancer, Alzheimer’s disease, and COVID-19 pneumonia. There is considerable evidence to support such beneficial use of low-dose radiation. If low-dose radiation had been studied for cancer prevention when it was proposed by Prof. T.D. Luckey in 1980, over 50 million cancer deaths would likely have been prevented worldwide during the past four decades.


DENIAL OF PETITON TO END THE LNT. In light of the enormous harm caused by regulations that are based on the LNT model, it is important to discontinue its use. In 2015, three petitions were filed with the NRC asking it to end the use of the LNT model. In these petitions, considerable evidence was presented demonstrating the cancer-preventive and therapeutic benefits of low-level radiation, contradicting the LNT model. However, instead of discussing the merits of the evidence and the petitions, the NRC quoted advisory bodies and simply dismissed the evidence and the petitions.


LAWSUIT. Since scientific evidence and reasoning have failed to persuade the NRC, it is necessary to explore additional approaches. We plan to launch a lawsuit against the use of the LNT model by regulatory agencies such as the NRC, the Environmental Protection Agency (EPA), and the U.S. Food and Drug Administration (FDA). Since the regulatory agencies justify their actions by quoting advisory bodies, we will also challenge and question advisory bodies such as the International Commission on Radiological Protection (ICRP), NCRP, and the National Academy of Sciences (NAS), for their neglect of the evidence supporting radiation hormesis and for their continued support of the LNT model.



• Reduction of the occurrence of cancers and deaths due to cancer

• Cancer treatments with low-dose radiation with very few adverse side effects

• Exploration of low-dose radiation for preventing and treating Alzheimer’s disease

• Much reduced cost of nuclear power due to elimination of unnecessary regulations

• Flourishing of nuclear power and plentiful low-cost electricity

• Economic development of poorer countries with minimal pollution


YOUR HELP. Presently, we have a unique courtroom opportunity because the NRC has denied the petitions to discontinue using the LNT model. We believe the NRC denied the petitions illegally and we have a certain amount of time to sue and to force the NRC to reconsider the petitions based on the best available science. Please click here to support our lawsuit with a generous donation. The lawsuit will be launched after $150,000 has been raised in donations.
