Linear No-Threshold Model VS. Radiation Hormesis.
The atomic bomb survivor cancer mortality data have been used in the past to justify the use of the linear no-threshold (LNT) model for estimating the carcinogenic effects of low dose radiation. An analysis of the recently updated atomic bomb survivor cancer mortality dose-response data shows that the data no longer support the LNT model but are consistent with a radiation hormesis model when a...
متن کاملRadiation Hormesis: an Evolutionary Expectation Invalidating the Linear No-threshold (lnt) Premise
Organisms survive best, or show high fitness, in the habitats in which they most commonly occur, a phenomenon referred to as hormesis in the literature of toxicology. Examples of hormesis accumulate rapidly in the literature. However, a lack of underlying models has led many to doubt its existence, especially for ionizing radiation. The evolutionary model developed here indicates that all poten...
متن کاملDestroying the Linear No-threshold Basis for Radiation Regulation
This article suggests five classes of effort that scientists can undertake to destroy the linear no-threshold hypothesis as the basis of radiation regulation in the United States. These are (1) pressure on regulators such as the Nuclear Regulatory Commission, (2) presidential messages, (3) Congressional pressure, (4) educate physicians about low-dose radiation, and (5) work with journalists and...
متن کاملRadiation Hormesis
The word “hormesis” is derived from the Greek word “hormaein” meaning: “to excite,” which is the origin of the word “hormone.” In 1902, the English physiologist, E. Starling, discovered that an acid extract from the human duodenum contained a substance designated as secretin that, when discharged into the bloodstream, stimulated the pancreas to release its secretions when food has passed throug...
متن کاملRadiation Hormesis Overview*
Evidence of health benefits and longer average life-span following low-dose irradiation should replace fear, “all radiation is harmful,” and “the perception of harm” as the basis for action in the 21 century. Hormesis is the excitation, or stimulation, by small doses of any agent in any system. Large doses inhibit. “Low dose” is defined as any dose between ambient levels of radiation and the th...
