ELECTROMAGNETIC LEAKAGE MONITOR "MINI-SURVEYOR" WITH 30 dB DYNAMIC RANGE
Unknown authors · 1977
Research on electromagnetic radiation leakage from microwave ovens operating at 2.45 GHz.
Your microwave oven is one of the most powerful EMF sources in your home, operating at 2.5 gigahertz with enough radiofrequency energy to heat water molecules in food. While these appliances are designed with shielding to contain most emissions, no microwave is perfectly sealed, and EMF exposure occurs both from leakage during operation and from standing waves that can extend several feet from the unit.

This 1977 technical report describes a portable device designed to detect electromagnetic leakage from microwave sources, specifically targeting 2450 MHz frequencies with 30 decibel measurement range. The device was developed as a mini-surveyor tool for monitoring microwave radiation emissions in various environments. While no specific health findings are detailed, this represents early recognition of the need to measure and monitor microwave radiation exposure levels.

In 1977, Health and Welfare Canada conducted a safety assessment of electromagnetic radiation exposure levels in and around Toronto's CN Tower, which was then the world's tallest structure. This government report evaluated potential health risks from the tower's broadcast antennas and transmission equipment. The study represents an early official examination of EMF exposure from major broadcasting infrastructure in urban environments.

This 1977 technical report reviewed the existing scientific literature on cancer-causing properties of both ionizing radiation (like X-rays) and non-ionizing radiation (including microwaves and radiofrequency fields). The analysis examined various forms of electromagnetic radiation to understand their potential role in cancer development. This represents one of the earliest comprehensive reviews connecting non-ionizing EMF sources to carcinogenic concerns.

The study describes two new food-industry applications of microwave power: roasting cocoa beans in Europe and drying egg-volk paste in Japan. Microwave roasting of cocoa beans proved highly effective and produced beans judged clearly superior to conventional methods. Microwave drying of egg-volk paste was found feasible and the product considered superior in characteristics to conventionally produced powder.

Model 1036 measures from -40 dBm to +10 dBm in a single range while Model 1037 measures from -30 dBm to +20 dBm. The instruments achieve rated accuracy of +0.02 dB on the upper 30 dB and +0.04 dB on the lower 20 dB of the power range. A self-check feature uses a front-panel calibrator providing 10 milliwatts accurate within +0.06 dB at 30 MHz. The detectors are protected against overloads up to 10 times full-scale rating and are field-repairable.
