short-term exposure to high levels of natural external gamma radiation does not induce survival adaptive response

Short-term exposure to high levels of natural external gamma radiation does not induce survival adaptive response

Background: In some areas of Ramsar, a city in northern Iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. Induction of adaptive response in residents of Ramsar has been reported previously. In this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. Materials and M...

Does short-term exposure to elevated levels of natural gamma radiation in Ramsar cause oxidative stress?

BACKGROUND Ramsar, a city in northern Iran, has areas with some of the highest recorded levels of natural radiation among inhabited areas measured on the earth. AIMS To determine whether short-term exposure to extremely high levels of natural radiation induce oxidative stress. MATERIALS AND METHODS In this study, 53 Wistar rats were randomly divided into five groups of 10-12 animals. Animal...

Does Occupational Exposure of Shahid Dastghieb International Airport Workers to Radiofrequency Radiation Affect Their Short Term Memory and Reaction Time?

Background: Airport workers are continuously exposed to different levels of radiofrequency microwave (RF/MW) radiation emitted by radar equipments. Radars are extensively used in military and aviation industries. Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile ...

Special Issue on The Challenging Issues of the Health Effects of Exposure to High Levels of Natural Radiation

Does short-term exposure to Wi-Fi waves affect the cognitive functions of the mind?

Introduction: In recent years, we have seen a tremendous growth in communications devices, such as mobiles and tablets. Also, the appeal to connect to the Internet through wireless systems has increased significantly. Given these changes in everyday life, the approach to cognitive works and problem-solving and decision-making in a complex system that has become increasingly imp...

Assessment of the role of specific absorption rate of mobile phones on the induction of microwave-induced survival adaptive responses after exposure to lethal doses of gamma radiation

Background: Whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. The main goal of this study was to assess the role of 900 MHz microwave radiations with different specific absorption rates (SARs), emitted from some widely used cell phones, on the induction of adaptive response in male Balb/c mice after receiving a lethal dose of gamma ...
