Low-dose radiation induces antitumor effects and erythrocyte system hormesis.
OBJECTIVE Low dose radiation may stimulate the growth and development of animals, increase life span, enhance fertility, and downgrade the incidence of tumor occurrence.The aim of this study was to investigate the antitumor effect and hormesis in an erythrocyte system induced by low-dose radiation. METHODS Kunming strain male mice were subcutaneously implanted with S180 sarcoma cells in the r...
متن کاملEvidence for beneficial low level radiation effects and radiation hormesis.
Low doses in the mGy range cause a dual effect on cellular DNA. One is a relatively low probability of DNA damage per energy deposition event and increases in proportion to the dose. At background exposures this damage to DNA is orders of magnitude lower than that from endogenous sources, such as reactive oxygen species. The other effect at comparable doses is adaptive protection against DNA da...
متن کاملRadiation 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 ...
متن کاملRadiation Hormesis in Humans Exposed to Low Level Ionizing Radiation
Through various researches and investigations it has been established that high doses of ionizing radiation are harmful to health. There is substantial controversy regarding the effects of low doses of ionizing radiation despite the large amount of work carried out (both laboratory and epidemiological). According to the linear no-threshold (LNT) hypothesis, any amount, however small, of radiati...
متن کاملNuclear energy and health: and the benefits of low-dose radiation hormesis.
Energy needs worldwide are expected to increase for the foreseeable future, but fuel supplies are limited. Nuclear reactors could supply much of the energy demand in a safe, sustainable manner were it not for fear of potential releases of radioactivity. Such releases would likely deliver a low dose or dose rate of radiation, within the range of naturally occurring radiation, to which life is al...
