BACKGROUND The aim of this study was to evaluate the effect of weak radiofrequency microwave (RF/MW) radiation emitted by mobile phones on colony growth of the yeast Saccharomyces cerevisiae. MATERIALS AND METHODS S. cerevisiae strains FF18733 (wild-type), FF1481 (rad1 mutant) and D7 (commonly used to detect reciprocal and nonreciprocal mitotic recombinations) were exposed to a 905 MHz electr...

This article gives a review or several hypotheses on the biological effects of non-thermal radiofrequency/microwave (RF/MW) radiation and discusses our own findings from animal and in vitro studies performed over the last decade. We have found that RF/MW radiation disturbs cell proliferation and leads to cell differentiation in the bone marrow, which is reflected in the peripheral blood of rats...

Introduction Most of the nuclear imaging systems require the use of a gamma (γ)-ray radiation shield to attenuate a stream of γ-rays so that only those traveling in a specified direction are allowed through and to absorb the scattered γ-rays from out of interest regions [1-2]. To meet those requirements, a γ-ray radiation shield is usually made out of lead (Pb) or some other high Z material suc...

Although the important role of the immune system in defending the human body against infections and cancer, only few studies on the possible effects of radiofrequency radiation on the function of human immune cells have been undertaken. The present study was performed to investigate whether radio frequency (RF) field exposure could affect the activity of human immune system cells by studying th...

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 experimentally investigate the outcoupling of atoms from Bose-Einstein condensates using two radiofrequency rf fields in the presence of gravity. We show that the fringe separation in the resulting interference pattern derives entirely from the energy difference between the two rf fields and not the gravitational potential difference between the two resonances. We subsequently demonstrate ho...

Bone-seeking radiopharmaceuticals (RF) are an effective systemic pain-palliative treatment schedule in patients with disseminated bone disease. This treatment relies on selective uptake and prolonged retention of RF at sites of increased osteoblastic activity, while the potential toxicity of systemic administration is reduced by relatively selective tumour targeting. The main theoretic advantag...

PURPOSE In the present study we investigated the possible histopathological effects of pulse modulated Radiofrequency (RF) fields on the thyroid gland using light microscopy, electron microscopy and immunohistochemical methods. MATERIALS AND METHODS Two months old male Wistar rats were exposed to a 900 MHz pulse-modulated RF radiation at a specific absorption rate (SAR) of 1.35 Watt/kg for 20...

During an MR procedure, most of the transmitted RF power is transformed into heat within the patient's tissue as a result of resistive losses. Not surprisingly, the primary bioeffects associated with the RF radiation used for MR procedures are directly related to the thermogenic qualities of this electromagnetic field. This review article discusses the characteristics of RF energy-induced heati...

We experimentally study the influence of 1-40 GHz radiation on the resistance of normal (N) mesoscopic conductors coupled to superconducting (S) loops (Andreev interferometers). At low radio-frequency (RF) amplitudes we observe the usual h/2e superconducting phase periodic resistance oscillations as a function of applied magnetic flux. We find that the oscillations acquire a π-shift with increa...
