Comparison of chromosome aberration and micronucleus induction in human lymphocytes after occupational exposure to vinyl chloride monomer and microwave radiation.

Micronucleus and chromosome aberration assays detected mutagenicity in lymphocytes from persons occupationally exposed to both vinyl chloride monomer and microwave radiation. The study reports quantitative and qualitative differences: VCM caused more overall …

The effect of microwave radiation on the cell genome.

Exposure to continuous 7.7 GHz radiation at 30 mW/cm2 inhibited [3H]thymidine incorporation by preventing DNA from entering S phase, with recovery of normal incorporation within one V79 generation cycle. Compared with controls, irradiated cells showed a highe…

[The combined action of microwave radiation and hydrogen peroxide on the viability and ultrastructure of Pseudomonas aeruginosa cells].

Combined microwave radiation plus hydrogen peroxide decreased P. aeruginosa viability by 1.5–2 times compared with the isolated action of each factor. Electron microscopy showed deterioration of surface structures and the nuclear and ribosomal apparatus under…

[Effect of ultra-high frequency electromagnetic energy on the rheologic properties of the blood].

In 150 rats exposed to microwave radiation (8 mm; 80 mVt/cm2) for 5 hours/day over 3 days, elevated blood viscosity (hyperviscosity) was observed using rotation and ultrasound viscometers at low and high shear frequencies. Hematocrit did not change; the visco…

Acute leukaemia in workers exposed to electromagnetic fields.

In a French case-control study (185 cases, 513 controls), occupational exposure to EMF other than from arc welding was associated with a significantly increased risk of acute leukaemia (odds ratio 4.04, 95% CI 1.26–12.88), persisting after adjustment for poss…

Thermographic studies of phantom and canine kidneys thawed by microwave radiation.

Microwave thawing produced non-uniform temperature distributions with frozen areas and/or hot spots in all phantom kidneys and in free-standing canine kidneys and gel-packed ethylene glycol-perfused kidneys. Glycerol- and dimethyl sulfoxide-perfused canine ki…

[Effect of electromagnetic SHF-radiation on the morphofunctional status of early mouse embryos].

A differential effect of 915 MHz microwave radiation (500 Hz amplitude modulation; 1 ms pulses) on the morphofunctional state of mouse 8-cell embryos was reported. Development was not disturbed by irradiation for 15 to 20 minutes.

Effects of pulsing electromagnetic fields on the prenatal and postnatal development in mice and rats: in vivo and in vitro studies.

PEMF at 20 and 50 Hz inhibited >50% of mouse blastocyst hatching and further development within 72 h in culture. In rat embryo culture, 50 and 70 Hz PEMF were associated with malformations (22% and 30%) and growth/developmental delay; TEM showed no significan…

Use of electric blankets and risk of testicular cancer.

In this case-control study, reported electric blanket use was similar in cases and controls (age-adjusted RR=1.0, 95% CI 0.7–1.4), and duration distributions were also similar. By subtype, electric blanket use was slightly lower for seminoma (RR=0.7, 95% CI 0…

The influence of microwave radiation on transdermal delivery systems.

Several transdermal delivery systems exposed to microwave radiation from a microwave diathermy unit showed temperature rises up to 2.2°C at a maximum power density of 800 W/m2. The authors considered these rises insignificant for producing a burn and conclude…

[The action of microwave radiation on potassium ion transport and oxygen consumption in the perfused rat liver].

Microwave irradiation (2450 MHz; specific absorbed power 0.1 to 5 W/g; continuous and pulsed-modulated) produced changes in potassium ion transport and oxygen consumption in perfused liver that did not differ from changes induced by heating the perfusate, sug…

Proflavin and microwave radiation: absence of a mutagenic interaction.

In L5178Y mouse leukemic cells, simultaneous exposure to 2.45-GHz pulsed-wave radiofrequency radiation (SAR ~40 W/kg for 4 h) and proflavin did not produce a statistically significant increase in induced mutant frequency compared with proflavin alone. No chan…

[Hygienic standardization of electromagnetic radiation from two-channel meteorological radar stations].

The study analyzed effects of combined EMF with wavelengths of 10 and 0.8 cm at various energy current density levels on central nervous system, metabolic processes, immune resistance, and reproductive function. Based on the obtained data, maximum allowable E…

Hematological changes in peripheral blood of workers occupationally exposed to microwave radiation.

Generation of microwave radiation in the tunneling junction of a scanning tunneling microscope.
