RF levels from various every-day devices compared to Smart Meters

These values are from a BGE filing to the MD PSC which simply quoted values from various industry studies.

RF Source	Distance	Power density (µW/cm²)
Microwave oven	5 cm from door (FDA limit)	5,000
Microwave	1 meter	10
Cell phone	at head	30-10,000
Cell phone base station	at ground level	1-12
Walkie-Talkie	at head	500-42,000
Wi-Fi router, access point	2.5m	10-20
Lap-top with Wi-Fi	1m	10-20
Smart meter	1 foot	8.8
Smart meter	25 feet	.005
Smart grid access point	25 feet	0.03

The following are from a study done by the AAEM in their attempt to show that these meters are dangerous. The table is copied from their report, with the power density unit of mW/m² converted to µW/cm² to allow comparison with the above table.

RF Source	Distance	Power density (µW/cm²)
Landis+Gyr Smart meter	3 ft	19.1
	10 ft	3.4
	20 ft	.4
	50 ft	.1

Note that the measurements vary widely because of the different configurations and situations being measured. However, it can quickly be seen that any radio-frequency "radiation" from Smart Meters is insignificant compared with many other sources that we take for granted.

Another interesting table in the AAEM report shows the power level measured in front, to the side, and behind the meter. The level behind it was 1/400 of that in font, thus demonstrating that the claim that occupants of the house on the other side of the wall are in special danger is really bogus.
