re: Smart meters coming

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

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.”(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.
