BioInitiative proposed safety level of radiation:
0.01 millionth of a watt per centimetre squared
Natural level of radiation:
 less than 0.000001 millionth of a watt per metre squared

In 2007, an international group of scientists studied 2000 peer-reviewed and published research papers.


They recommended an acceptable level of radiation of not more than 0.6 V/m = ~1μW/cm2 outdoors, and 0.2 V/m = ~0.1 μW/cm2 indoors, based on the interaction between low-level microwaves and the cellular processes.

This became known as the Bioinitiative Level,
which has since been lowered by a factor of 10, to 0.01 μW/cm2.

The New Zealand safety limit (NZ2772.1.1999) for the specific absorption of radiation from transmitters close to the body (ie cell phones) is 2W/KG over any 10 grams of body tissue. This standard is really based on protecting the body from heating effects, please check the New Zealand government information site.
