re: Smart meters coming

[Guest guest]

How did they get away w overexposing limits to start? These pulse 24/7. 

From the sage Report

Smat meters & cell phones exposure standards were done for 6 & 30 mins!

RF  up to1500 MHz were approved as IF they were 300 GHz. 

In the frequency range from 100 MHz to 1500 MHz, exposure limits for

field strength and power density are also generally based on the MPE

limits found in Section 4.1 of “IEEE Standard for Safety Levels with Respect

to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300

GHz,†ANSI/IEEE C95.1-1992 ( IEEE, 1992, and approved for use as an American

National Standard by the American National Standards Institute (ANSI).

NOTE 1: Occupational/controlled limits

apply in situations in which persons are exposed as a consequence of

their employment provided those persons

1st for occupational exposure

NOTE 2: General population/uncontrolled

exposures apply in situations in which the general public may be

exposed, or in which persons that are exposed as a consequence of their

employment

 may not be fully aware of the potential for exposure or can

not exercise control over their exposure. Source: FCC

Bulletin OET 65 Guidelines, page 67 OET, 1997.

In this report, the public safety limit for a smart meter is a

combination of the individual antenna frequency limits and how much

power output they create. A smart meter contains two antennas.

One

transmits at 915 MHz and the other at 2405 MHz. They can transmit at

the same time, and so their effective radiated power is summed in the

calculations of RF power density. Their combined limit is 655 uW/cm2.

For the collector meter, with it’s three internal antennas, the

combined public safety limit for time-averaged exposure is 571 MHz (a

more restrictive level since it includes an additional 824 MHz antenna

that has a lower limit than either the 915 MHz or the 2405 MHz

antennas).

In a collector meter, only two of the three antennas can

transmit simultaneously (the 915 MHz LAN and the GSM 850 MHz (from the

FCC Certification Exhibit titled RF Exposure Report for FCC ID:

SK9AMI-2A).

The proportionate power output of each antenna plus the

safety limit for each antenna frequency combines to give a safety limit

for the collector meter of 571 uW/cm2.

Where one collector meter is

combined with multiple smart meters, the combined limit is weighted

upward by the additional smart meters’ contribution, and is 624 uW/cm2.

Reflections can significantly increase localized RF levels.

Hondou et al (2006) establishes that power densities 1000 times to 2000

times higher than the power density predictions from computer modeling

(that does not account properly for reflections) can be found in daily

living situations. The RF hot

spots created by reflection can significantly increase RF exposures to

the public, even above current public safety limits.

No one was wanred this would do this kind of damage.

“In the case of the eyes and testes, direct relaxation of power density limits

is not permitted.â€(p. 30)

This leaves unanswered what instantaneous peak power is permissible

from smart meters. The level must be below 4000 uW/cm2. This report

shows clearly that smart meters can create instantaneous peak power

exposures where the face (eyes) and body (testes) are going to be in

close proximity to smart meter RF pulses. RF levels at and above 4000

uW/cm2 are likely to occur if a person puts their face close to the

smart meter to read data in real time.
