A Radiofrequency Radiation Exposure Apparatus
نویسندگان
چکیده
A radiofrequency radiation exposure apparatus has been developed and placed into operation at the USAF School of Aerospace Medicine, Brooks AFB, Tex. The rectangular coaxial device has dimensions of 4% ft. by 9% ft. by 30 ft., with a 6-ft.-wide center conductor. It is powered by a B0-kwp. transmitter and operates in a pulsed mode at frequencies of 10.5, 19.27, and 26.6 MHz. Up to 12 animals (Macaco, mulatto.) can be exposed simultaneously to uniform fields ranging in power density from 0.05 to 0.2 w./cm. The instrumentation system, consisting of portable Eand H-field probes and fixed E-field probes, was developed and calibrated by the National Bureau of Standards. Details of the system design, checkout, and operation are presented.

Adaptive Response Induced by Pre-Exposure to 915 MHz Radiofrequency: A Possible Role for Antioxidant Enzyme Activity
Background: Over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. Adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. This study aimed to assess whether radiofrequency radiation can induce adaptive r...
متن کاملExposure to Radiofrequency Radiation Emitted from Common Mobile Phone Jammers Alters the Pattern of Muscle Contractions: an Animal Model Study
Introduction: The fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. To disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofreque...

متن کاملKlebsiella pneumonia, a Microorganism that Approves the Non-linear Responses to Antibiotics and Window Theory after Exposure to Wi-Fi 2.4 GHz Electromagnetic Radiofrequency Radiation
Background: Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...
متن کاملEffect of Exposure to 900 MHz GSM Mobile Phone Radiofrequency Radiation on Estrogen Receptor Methylation Status in Colon Cells of Male Sprague Dawley Rats
Background: Over the past several years, the rapidly increasing use of mobile phones has raised global concerns about the biological effects of exposure to radiofrequency (RF) radiation. Numerous studies have shown that exposure to electromagnetic fields (EMFs) can be associated with effects on the nervous, endocrine, immune, cardiovascular, hematopoietic and ocular systems. In spite of genetic...
متن کامل“Triple M†Effect: A Proposed Mechanism to Explain Increased Dental Amalgam Microleakage after Exposure to Radiofrequency Electromagnetic Radiation
A large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (RF-EMFs) such as common mobile phones and magnetic resonance imaging (MRI). Studies performed on the increased microleakage of dental amalgam restorations after exposure to RF-EMFs have further supported th...
