ACGIH stated in 1980 that insufficient knowledge existed to set guidelines for magnetic field exposures. Existing laboratory guidelines had little basis beyond being levels considered safe in the 1960s.

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.

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.

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.

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.

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.

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.
