“…For a central flux density of 2 x 10"'* tesla (2 gauss), the stray field 3.75 m away is 8.8 x 10"^t esla (8.8 milligauss) which is more than three times the ambient magnetic field levels reportedly found in homes [30].…”

“…Other investigators have published limited reports of MFD and, in some cases, electric field (E-field) measurements in or near homes [Caola et al, 1983;Male et al, 1987;Norris et al, 1987;Tomenius, 1986;Deno, 1987;Gauger, 19851. Some relevant results of these papers are as follows:…”

A magnetic flux density (MFD) and electric-field (E-field) data-acquisition system was built for characterizing extremely low-frequency fields in residences. Every 2 min during 24-h periods, MFD and E-field measurements were made in 43 homes in King, Pierce, and Snohomish counties of Washington State. The total electrical energy used in each residence during the 24-h measurement period was also recorded, and maps were drawn to scale of the distribution wiring within 43 m (140 ft) of these homes. Finally, on a separate date, field measurements were made in each home during an epidemiological interview. The results of this study can be summarized as follows: 1) 24-h-average MFD measured at two separate points in the family room were correlated, as were a 24-h-average bedroom measurement and the mean of the two family-room measurements. 2) The 24-h-average family-room MFD and E-field measurements were uncorrelated. 3) The 24-h-average total harmonic distortions of family-room MFD and E-fields were less than about 24% and 7%, respectively. 4) Residential MFD exhibited a definite 24-h (diurnal) cycle. 5) The 24-h-average and interviewer-measured MFD were correlated. 6) Residential 24-h-average MFD were correlated with the wiring code developed by Wertheimer and Leeper. 7) An improved prediction of 24-h-average residential MFD was obtained using the total number of service drops, the distance to neighboring transmission lines, and the number of primary phase conductors.

“…However, the magnetic field strength decreases rapidly as a function of distance from the surfaces of household devices (28), and the ambient field levels at most locations within a household environment are generally less than 0. 3 p,T (17,57,90). The video display terminals present in most offices generate local ELF magnetic fields with flux densities up to 5 p,T, although the typical exposure level at the operator's location is less than 1 p,T (93,107).…”
