متن کاملLow Doses and Radiation Risk in vivo
The “Linear No Threshold” hypothesis, used in all radiation protection practices, assumes that all doses, no matter how low, increase risk. However, in human and other mammalian cells, low doses of low LET radiation such as gamma and X-rays induce an adaptive response that protects against both radiation-induced and spontaneous risk. An in vivo test of the hypothesis in mice showed that a 100-m...
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 کاملLow-dose radiation exposure and carcinogenesis.
Absorption of energy from ionizing radiation by the genetic material in the cell leads to damage to DNA, which in turn leads to cell death, chromosome aberrations and gene mutations. While early or deterministic effects result from organ and tissue damage caused by cell killing, latter two are considered to be involved in the initial events that lead to the development of cancer. Epidemiologica...
متن کاملCarcinogenesis Induced by Low-dose Radiation
Background Although the effects of high dose radiation on human cells and tissues are relatively well defined, there is no consensus regarding the effects of low and very low radiation doses on the organism. Ionizing radiation has been shown to induce gene mutations and chromosome aberrations which are known to be involved in the process of carcinogenesis. The induction of secondary cancers is ...
