The assessment of function, histopathological changes, and oxidative stress in liver tissue due to ionizing and non-ionizing radiations
Background: Compared to past decades, humans are exposed to rapidly increasing levels of radiofrequency electromagnetic radiations (RF-EMF). Despite numerous studies, the biological effects of human exposure to different levels of RF-EMF are not fully understood, yet. This study aimed to evaluate the bioeffects of exposure to "900/1800 MHz" and “2.4 GHz" RF-EMFs, and x-rays as well as their pot...
متن کاملDetection of ionizing radiation emitted from the cesium-137 and cobalt-60 sources using electrochemical superoxide anion sensor in the aqueous medium
Widespread use of ionizing radiation in medicine, industry, agriculture, education and research, the increasing production of nuclear waste and nuclear incidents, has exposed humans and organisms to this radiation. Despite the benefits of ionizing radiation, these beams can cause serious damage to living systems. Hence, the need for radiation protection actions requires accurate, fast, inexpens...
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 کاملThe Bystander Effect of Ultraviolet Radiation and Mediators
A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, ch...
متن کاملEffects of microwave electromagnetic radiations emitted from common Wi-Fi routers on rats’ sperm count and motility
Background: Wi-Fi allows electronic devices such as laptops to exchange data or connect to a network resource. The main goal of this study was to assess the bioeffects of short term exposure to 2.4 GHz microwave radiation emitted from a common Wi-Fi router on sperm quality. Materials and Methods: Male Wistar rats were divided into 7 groups; I, sham exposed 4 h/day for 7days at 30 cm from ...
