Radiofrequency radiation-induced calcium ion efflux enhancement from human and other neuroblastoma cells in culture

Human neuroblastoma cells exposed to 147 MHz radiofrequency radiation amplitude-modulated at 16 Hz showed significant 45Ca2+ efflux at SAR values of 0.05 and 0.005 W/kg. At 0.05 W/kg, enhanced efflux peaked at modulation ranges 13–16 Hz and 57.5–60 Hz. A Chin…

Low intensity microwave radiation effects on the ultrastructure of Chang liver cells.

Exposure to 2450 MHz microwaves at 5–20 mW/cm2 for up to 2 h was associated with intensity- and duration-dependent ultrastructural alterations in Chang liver cells. At 10 mW/cm2 for 30 min, cytoplasmic lesions with degenerated RER were observed; longer exposu…

Effect of metal-framed spectacles on microwave radiation hazards to the eye of humans.

Using a monopole antenna probe and subtraction method in an anechoic chamber, the study measured changes in microwave fields near the eyes when metal-framed spectacles were introduced. In certain cases, spectacles increased field levels by up to approximately…

[Functional status of the developing body as a criterion of hygienic standardization of electromagnetic fields of 2750 MHz].

The study reports elevated sensitivity of developing (nonmature) white rats to exposure from a 2750 MHz electromagnetic field. Based on this, a hygienic standard for 2750 MHz EMF for the population was set at 15 mW/cm2.

Effects of microwave radiation on the eye: the occupational health perspective.

This overview reports that experimental animals can develop lens opacities at relatively high microwave intensities (>100 mW/cm2), and that at lower intensities lens changes may depend on cumulative dose. It describes animal findings including synergistic eff…

Acute thermoregulatory responses of the immature rat to warming by low-level 2,450-MHz microwave radiation.

Colonic temperature increased significantly above initial level at both 5 and 20 mW/cm2 exposures and plateaued after 45 minutes; the increase was larger at higher intensity. Metabolic heat production remained unchanged during exposure at 5 mW/cm2 but decreas…

Results of a United States and Soviet Union joint project on nervous system effects of microwave radiation.

Male Fischer 344 rats were exposed or sham exposed to 10 mW/cm2 continuous-wave microwave radiation at 2.45 GHz for 7 hr. Neither group observed a significant effect on open field activity. Both groups observed changes in variability in passive avoidance data…

Effects of 50-hertz electromagnetic fields on proliferation and on chromosomal alterations in human peripheral lymphocytes untreated or pretreated with chemical mutagens.

Culturing human peripheral lymphocytes with 50-Hz EMFs did not change spontaneous sister-chromatid exchange or chromosomal aberration frequencies, but was associated with enhanced cell cycle progression in vitro. After pretreatment with chemical mutagens (tre…

The differentiation of normal and transformed human fibroblasts in vitro is influenced by electromagnetic fields.

Exposure to symmetric, biphasic sinusoidal EMF (20 Hz, 6 mT) for up to 21 days induced differentiation of normal human skin and lung fibroblasts from mitotic to postmitotic cells, with significantly increased total collagen and total cellular protein (reporte…

Microwave cataract and litigation: a case study.

The paper summarizes an Australian court case regarding a radar technician’s claim that microwave exposure caused subcapsular posterior cataracts. The court ruled it was probable that the level of microwave exposure did not cause or accelerate the cataracts o…

[Clinical variants of the disease caused by exposure to radio-frequency electromagnetic fields].

Clinical data describing characteristics of the course of disease caused by microwave radiation are presented. The abstract states an assumption that clinical features are specified by radiation "geometry".

Scattering of linearly polarized microwave radiation from a dielectric target including the interaction between target elements.

A theory is presented to calculate the internal field within a dielectric helix for incident linearly polarized microwave radiation when the wavelength is larger than the helix wire diameter. Including target self-interactions significantly affects the intern…

Cell surface changes during electromagnetic field exposure.

Chick embryo fibroblasts exposed to a constant electromagnetic field of 10 V/cm underwent sequential morphological changes, including elongation perpendicular to the field and migration toward the cathode. These changes were associated with cell surface alter…

Enhancement of the kinetics of the aeration of ethylene oxide sterilized polymers using microwave radiation.

Microwave heating at 2.45 GHz accelerated diffusion/desorption of ethylene oxide from polyvinylchloride compared with conventional heating at the same macroscopic temperature, with reported degassing time savings of up to 400%. The abstract reports that micro…

[Microwave radiation treatment of liver cancer: animal experiment and preliminary clinical application].

In animal experiments using 2450 MHz microwave treatment, air bubbles formed in liver tissue and small veins when the radiated center temperature exceeded 80°C and were markedly reduced when temperature was controlled around 65°C. The radiated liver showed ne…
