Radiation Hormesis: Demonstrated, Deconstructed, Denied, Dismissed, and Some Implications for Public Policy
نویسنده
چکیده
The prevailing view of regulatory agencies and advisory groups is that all radiation is bad for health, and exposure to any form of it should be minimized. While high-dose radiation, regardless of source or intention, is harmful to health, evidence is presented that chronic doses up to 100 times those of normal ambient (including medical) exposures are beneficial, mainly due to lower cancer rates. Further evidence is presented that single, acute doses of up to 50 rad are beneficial, including in treatment of cancer and gangrene. Data are cited to show that below-ambient radiation levels are unhealthful, and that some radiation may be essential for many life-forms.

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 ...

Cook and Calabrese (2006) make inaccurate claims about our perspective on hormesis (Thayer et al. 2005). They define hormesis as “low-dose stimulation and high-dose inhibition,” declaring “beneficial/ harmful effects should not be part of the definition, but reserved to subsequent evaluation. . . .” Yet, they advocate higher permissible environmental levels of hazardous agents based on purporte...

Today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “NUCLEAR” can induce worries in patients and society. In this article, base on new documents, we intend to show that this worries has no scientific basis. To produce a realistic view, ...
متن کاملThe Importance of Hormesis to Public Health
Hormesis is a specific type of nonmonotonic dose response whose occurrence has been documented across a broad range of biological models and diverse types of exposure. The effects that occur at various points along this curve can be interpreted as beneficial or detrimental, depending on the biological or ecologic context in which they occur. Because hormesis appears to be a relatively common ph...
متن کاملHormesis: implications for cancer risk assessment.
Current guidelines for cancer risk assessment emphasize a toxicant's "mode of action", rather than its empirically derived dose-response relationship, for determining whether linear low-dose extrapolation is appropriate. Thus, for reasons of policy, demonstration of hormesis is generally insufficient to justify a non-linear approach, although it may provide important insights into the actions o...
