A document prepared by smart meter manufacturer EDMI shows that its GPRS modem EWM100 produces less microwave radiation than the level permitted by the NZ legal standard NS2772.1:1999 but still a very large amount of radiation nonetheless.
As you can see from the attached document, the modem can produce pulses of microwave up to 1,990,000 microwatts per square metre.
Given that the scientists who compiled the BioInitiative Report (www.bioinitiative.org) consider that 1,000 microwatts per square metre is a suitable upper limit for human exposure, the level of radiation produced by the modem is a serious concern.
Due to the high amount of radiation produced by the modem EDMI recommends that signs be used to warn people who may spend any large amount of time next to the modem (such as might occur if the smart meter were on the wall of their bedroom or next to a chair where they work.) however, I am not aware of any case in NZ where4 any smart meter installer has put up a warning notice regarding the microwave radiation hazard posed by a smart meter.
