Harms from the use of the LNT model


The use of the LNT model led to

  • considerable concerns regarding even very low levels of radiation



  • adverse effect on public health because LNT model discouraged/blocked study of low-dose radiation for the prevention and treatment of major and currently intractable diseases such as Alzheimer's and Parkinson's diseases and cancer, though evidence supports its consideration for such diseases

Mayak - Evacuated residents of villages near Mayak Nulcear Weapons Facility (Kostyuchenko, 1994)

Significant reduction of cancers observed following low-dose radiation exposure, but could not be investigated because of the LNT model

Not much progress in the war on cancer in 50 years

  • considerable casualties, tremendous economic loss, and disruption of normal life due to precautionary evacuations following nuclear accidents, e.g. in Fukushima, but no benefit.

  • harm to patients due to misdiagnoses/missed diagnoses because of patients/parents refusal of diagnostic studies and doctors not prescribing diagnostic studies, and non-diagnostic imaging studies performed due to misguided dose-reduction efforts.

  • increased power generation costs due to ratcheting up of radiation safety regulations for nuclear power plants

Note: LNT model, ALARA, and low-dose radiation concerns as well as other factors contributed to the observed increased costs over the years.



  • barriers to development of underdeveloped countries as low-dose radiation concerns have suppressed development of nuclear power in spite of it being the cheapest, safest, least-polluting mode of energy generation. Lack of power is a major constraint for development.

Considering the major harms caused by the use of the LNT Model, there would indeed be major potential benefits from discarding the LNT model:
