At industrial sites, Vitale has measured EMF levels from equipment as high as thousands of milligauss
Target-site readings ranged from 1 milligauss to 30 milligauss, whereas those at control sites ranged from 1 milligauss to 100 milligauss.
Four target sites had peak magnetic-field magnitudes of 10 milligauss or more, as compared with only one control site that displayed a peak of 100 milligauss.
An electromagnetic probe placed in the path of another orb recorded a field of 120 milligauss
Six sites exceeded the norm for GMFs by 200 milligauss
(mG) or more.
In the Theater on the fourth floor, Nichols recorded a transient temperature decrease that coincided with a geomagnetic field (GMF) anomaly that exceeded 100 Milligauss, the maximum threshold of the meter.
Nichols recorded a GMF strength of 157 Milligauss, as compared to the ambient field of 2-3 Milligauss in the rest of the Castle.
In fact, some studies have shown that constant exposure to just two milligauss
(the units in which EMFs are measured) is enough to cause childhood leukemia.
Gillette, who directed the study, reports that riding in cars or electric subways exposed the volunteers to electromagnetic fields of 200 to 300 milligauss
-- four to eight times stronger than those generated by computer terminals at work.
The book said measurements at various places near our Guilford substation fence gave readings between 20 and several hundred milligauss
but does not say who took them or where they were taken.
