Radiation hormesis is the hypothesis that low doses of ionizing radiation (within the region of and just above natural background levels) are beneficial, stimulating the activation of repair mechanisms that protect against disease, that are not activated in absence of ionizing radiation.
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
The validity of the LNT model, however, is disputed, and other models exist: the threshold model, which assumes that very small exposures are harmless, the radiation hormesis model, which says that radiation at very small doses can be beneficial, and the supra-linear model. It has been argued that the LNT model may have created an irrational ...
The following table includes some dosages for comparison purposes, using millisieverts (mSv) (one thousandth of a sievert). The concept of radiation hormesis is relevant to this table – radiation hormesis is a hypothesis stating that the effects of a given acute dose may differ from the effects of an equal fractionated dose. Thus 100 mSv is ...
Radiation exposure from radon is indirect. The health hazard from radon does not come primarily from radon itself, but rather from the radioactive products formed in the decay of radon. [1] The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only ...
However, my study was designed to test the assumption that the danger of radiation is simply proportional to the radiation dose, which is the only evidence that low-level radiation may be harmful. My conclusion was that that assumption is false." [1] [6] [11] Other scientists disagree [12] [13] and more research has been called for. [14]
Consider these two statements (bold is my addition) from the hormesis article - In the intro: "Radiation hormesis (also called radiation homeostasis) is the hypothesis that low doses of ionizing radiation (within the region and just above natural background levels) are beneficial, stimulating the activation of repair mechanisms that protect ...
To put it in the same paragraph as radiation hormesis just makes LNT look like a safe middle ground, a place which it does not occupy. LNT is the extreme upper limit on low-level radiation damage in the literature, and should not be made to look like a middle of the road estimate.
