The Property Survey

Based on the findings of a property survey, it is possible to provide specific recommendations for any planned construction activity. Anticipated fu­ture developments in the neighborhood should also betaken into consideration.

First, map the naturally occurring terrestrial ra­diation pattern to detect anomalies in the Earth’s magnetic field as well as radioactivity.

Second, assess the risk of power frequency fields. Be aware that on days with little moisture in the air the electric fields from high-tension power lines might be overestimated, although in many cases building materials will attenuate the exter­nal fields. In contrast, alternating magnetic fields are mostly independent of the weather. Because power consumption fluctuates over any given day, week, or even season, data logging is neces­sary for proper risk assessment.

Third, measure RF radiation. Radio waves, or microwaves, ride along the airwaves with an inten­sity that varies with the distance from the source of emission and the time of day. To accurately as­sess the highly complex web of electromagnetic waves, data logging is a must. The main direction and specific frequency bands of the major sources of RF radiation need to be carefully monitored so that appropriate shielding advice can be given.

Remember that in creating a safe electrocli­mate in your bedroom any attainable reduction is worthwhile and nature is the ultimate guide.

main or subpanel as well as on all connected outlets. To maintain proper functioning of an automatic demand switch in the long run, you should test it by inserting a control lamp once a month, just as you would test a ground fault circuit interrupter (GFCI).

If elevated AC electric fields originate from neighboring apartments or adjoining houses, demand switches will not help and shielding strategies will have to be explored.
