What are the safety regulations.
The current regulations are based on a measure called Specific Absorption Rate (SAR). This is a measure of how much electromagnetic energy is absorbed by your body tissue. The regulations are set by a number of different bodies around the world. In the United States of America the Federal Communications Commission (FCC) has adopted the specific absorption rate (SAR) limits of 1.6 W/Kg (averaged over 1g of tissue) for devices operating within close proximity to the body as specified within the American National Standards Institute (ANSI) and the Institute for Electrical and Electronics Engineers (IEEE) (1).
The International Commission on Non-ionising Radiation Protection (ICNIRP) also provides guidelines for safe use of non-ionising radiation and these guidelines are adopted by a number of countries around the world. The ICNIRP is a charitable body of independent scientific experts established by the International Radiation Protection Association whose aim is to circulate information and advice on the possible health hazard of exposure to non-ionising radiation, including electromagnetic radiation from mobile phones (2). The ICNIRP guidelines state that 2 W/Kg (averaged over 10g of tissue) should not be exceeded by the general public. In March 2004 the recommendation of the Health Protection Agency (HPA) for the UK to adopt the ICNIRP guidelines, was accepted by the UK Government (2).
