Background: The health effect of rapidly increasing everyday exposure of humans to radiofrequency radiation is a major global concern. Mobile phone jammers prevent the mobile phones from receiving signals from base stations by interfering with authorized mobile carriers’ services. In spite of the fact that mobile jammer use is illegal, they are occasionally used in offices, shrines, confe...

physical agents such as ultraviolet or ionizing radiation and repetitive trauma have been related to the causation of cancer in humans. much less clear is the association between exposure to radiofrequency, such as radar and microwave radiation to the development of cancer. sporadic case reports and small series suggest that this type of radiation might lead to cancer or contribute to its evolu...

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...

Although exposure to electromagnetic radiation in radiofrequency range has caused a great deal of concern globally, radiofrequency radiation has many critical applications in both telecommunication and non-communication fields. The induction of adaptive response phenomena by exposure to radiofrequency radiation as either increased resistance to a subsequent dose of ionizing radiation or resista...

Radiofrequency radiation dosimetry describes how this radiation is being absorbed in the body. The basic units of measuring the radiofrequency exposure are the electric E (V/m), magnetic B (A/m) field strength, the power density S (W/m 2 ), and the Specific Absorption Rate (SAR) (W/kg). Many studies have made use of different types of instruments to assess the level of radiofrequency radiation ...
