RADIATION HORMESIS OF FIELD-SEEDED BROCCOLI, PARSNIP AND CAULIFLOWER

Radiation 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...

Radiation 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...

Hormesis and radiation safety norms.

Today's radiation safety norms are based on the linear no-threshold theory (LNT): extrapolation of the dose-response relationships down to the minimal doses, where such relationships are unproven and can be inverse due to hormesis. The most promising way to obtaining reliable data on the dose-effect relationships for low radiation doses would be large-scale animal experiments. Outstanding publi...

Radiation hormesis and adoptive response induced by low doses of limiting radiation

  Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems  to be induced at low doses of exposure. In recent decades, however, some pioneer scientists have indicated that ionizing radiation like many other essential agents has toxic effects  ...
