Electric-Field Exposure of Persons Using Video Display Units

S.M. Harvey · 1984

Researchers measured electric fields from four video display units over a frequency range from DC to 1 MHz using a capacitive sensor on a simple simulation of the human body. The electric fields were the sum of three components from the charged CRT screen, the flyback transformer, and the low-voltage circuitry. Flyback transformer fields had pulse repetition rates of 15.8 to 18.5 kHz with peak-to-peak amplitudes of 19 to 170 V/m and rms amplitudes of 4 to 35 V/m. CRT fields showed DC magnitudes of 300 to 7,000 V/m after 0.5 hours and rms modulation amplitudes of 10 to 65 V/m. Operator exposures were typically two to three orders of magnitude below permitted exposure limits, leading to the conclusion that these VDUs present no hazard within existing guidelines.

ELECTROMAGNETIC BIOLOGY: AN UPDATE ON SOME CURRENT ISSUES

Christopher H. Dodge, Zorach R. Glaser · 1984

The presentation was designed to enumerate actions taken by U.S. governmental groups on RF issues during the previous two years. The authors intended to point out the inconclusive and insufficient nature of the RF bioeffects and health effects databases. They also planned to note the difficulty of applying risk assessment to the available data.

VDT radiation: What's known, what isn't

Louis Slesin · 1984

The article reviews concerns about radiation from video display terminals (VDTs) in the workplace. VDTs emit very low frequency (VLF) radiation from the flyback transformer at about 16,000 pulses per second. The VLF pulses are similar in shape and intensity to those that caused adverse effects on chick embryos in Delgado's laboratory. Eleven clusters of problem pregnancies and miscarriages have been reported among women working on or near VDTs in the U.S. and Canada.

Inexpensive Microwave Oven Survey Instruments: An Evaluation

Donald M. Witters, Jr., William A. Herman · 1984

The study tested nine commercially available inexpensive microwave survey instruments for calibration, polarization sensitivity, amplitude modulation response, and overload sensitivity. The Micromate yielded warning readings at 0.6 to 1.9 mW/cm², while the Guard-Rod ranged from 3.7 to 47 mW/cm² depending on measurement surface. Several instruments showed large sensitivity changes with polarization and amplitude modulation. Some instruments suffered overload damage that reduced sensitivity without user indication. The Seeker had two versions with very different performance that users could not distinguish.

WEST GERMANY PUBLISHES EMF EXPOSURE STANDARD

Thomas C. Rozzell · 1984

The article reports that West Germany published its first official human-exposure guidelines for electromagnetic fields, applicable to both workers and the general public. The German standard covers frequencies from 0.01 MHz to 3900 GHz, which is wider than the ANSI standard’s 0.1 MHz to 100 GHz range.

Radiofrequency radiation and the immune system. Part 3. In vitro effects on human immunoglobulin and on murine T- and B-lymphocytes

Robert P. Liburdy, Alan Wyant · 1984

Researchers exposed human serum to a 10 MHz electric field during liquid gel chromatography and murine spleen lymphocytes to 2500MHz RFR during immunoaffinity cell chromatography. The 10 MHz exposure accelerated elution of IgM, IgA, and IgG fractions, with the IgG peak shifting from approximately 165 ml to 150 ml. The 2500MHz RFR exposure caused premature elution of 19 per cent of the Ig* (B-cell) population, indicating an alteration of Ig binding. No measurable heating occurred; the gel media temperature remained at 25-00 +0-05°C and temperature excursions in excess of +0-05°C were not observed.

Instrumentation for Nonionizing Radiation Measurement

Unknown authors · 1984

The document was prepared by the Conference of Radiation Control Program Directors and the National Center for Devices and Radiological Health. It covers three categories of nonionizing radiation: radiofrequency radiation including microwave, optical radiation, and acoustic radiation. For radiofrequency, 60 Hz fields, and ultrasound, most commercially available instruments are listed, while for optical measurements only representative instruments are included. Instrument specifications are taken from manufacturer data sheets and have not been verified by the publishing agencies.

Microwave Bioeffects in the Erythrocyte Are Temperature and pO₂ Dependent: Cation Permeability and Protein Shedding Occur at the Membrane Phase Transition

R.P. Liburdy, A. Penn · 1984

Researchers exposed rabbit erythrocytes to 2450 MHz continuous-wave microwaves at 60 mW/g and used sham exposures with the waveguide unenergized. Sodium-22 influx increased by 75-100% only at the membrane phase transition temperature of 17.7-19.5 °C. The permeability increase was amplified at intracellular oxygen tension (0-5 mm Hg) and at hyperoxic conditions (760 mm Hg), but was least pronounced at arterial and atmospheric oxygen tension. Microwave exposure at the phase transition temperature caused shedding of at least 11 proteins under 28,000 D, including two unique bands at 26,000 and 24,000 D. Approximately 450 fg of protein were estimated to be released per erythrocyte.

Differences in DMBA-induced mammary neoplastic responses in two lines of Sprague-Dawley rats

Unknown authors · 1984

Researchers gave 10 mg of DMBA per 100 g body weight by stomach tube to rats from two sources. Dutch-source rats showed about 25% carcinoma and 18% fibroadenoma rates after 367 days. U.S.-source rats showed 90-100% carcinoma and 83-95% fibroadenoma rates after 300 days.
