During the last two decades, the number of macrocell mobile telephony base station antennas emitting radiofrequency (RF) electromagnetic radiation (EMR) in residential areas has increased significantly, and therefore much more attention is being paid to RF EMR and its effects on human health. Scientific field measurements of public exposure to RF EMR (specifically to radio frequency radiation) ...

We demonstrate an active, implantable drug delivery device embedded with a microfluidic pump that is driven by a radio-controlled actuator for temporal drug delivery. The polyimide-packaged 10 × 10 × 2 mm(3) chip contains a micromachined pump chamber and check valves of Parylene C to force the release of the drug from a 76 μL reservoir by wirelessly activating the actuator using external radio-...

In the past few years, radio frequency (RF) devices, which are usually used in the vicinity of a human body, are increasing. The health effects of the electromagnetic (EM) waves from RF devices on the human body are dependent on the frequency and strength of the waves. The absorbed RF EM energy mainly contributes to tissue heating. The specific absorption rate (SAR) has been used as the standar...

background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...

Exposure to radio frequency electromagnetic fields has raised scientific and public concern regarding possible adverse effects to people exposed to such radiation. At cellular mobile communication frequencies, the most important parameter used to assess human exposure to electromagnetic fields is SAR (Specific Absorption Rate). This paper will firstly address two exposure scenarios related to a...

Introduction Electromagnetic wave propagation in tissue is known to cause dielectric resonance effects if the wavelength reaches the object dimension. At 3.0T, dielectric resonance effects are visible in body MR imaging predominantly in heavier patients and in patients with intraabdominal fluid collections (i.e. ascites). The use of multiple transmit channels can provide better control of the r...

A case-control study of radio frequency electromagnetic fields (RF-EMFs) and childhood leukemia was conducted in West Germany. The study region included municipalities near high-power radio and TV broadcast towers, including 16 amplitude-modulated and 8 frequency-modulated transmitters. Cases were aged 0-14 years, were diagnosed with leukemia between 1984 and 2003, and were registered at the Ge...

Absorption of pulsed microwave nergy can produce an auditory sensation in human beings with normal hearing. The phenomenon manifests itself as a clicking, buzzing, or hissing sound depending on the modulatory characteristics of the microwaves. While the energy absorbed (--• 10/z J/g) and the resulting increment of temperature (--• 10 -6 øC) per pulse at the threshold of perception are small, mo...
