The following is an abstract from a positioning statement issued by the Institution of Engineering and Technology in UK in May 2008.  The statement is entitled "The possible harmful biological effects of low level electromagnetic fields of frequencies up to 300GHz".  The range of frequencies covers computers, mobile phones & radio uses. The full statement can be downloaded at www.theiet.org/factfiles/bioeffects/.  The abtract is replicated here for the convenience of Compucon user community members only and it should not be relied upon as an official guide.  Compucon does not own the copyright of the abstract.


The Institution of Engineering and Technology (IET) has a special interest in any possible health effects of occupational exposure to electromagnetic fields (EMFs) as well as in any due to exposure of the population at large. The IET remains determined to be at the forefront of rigorously examining the scientific evidence for any such effects and identifying any hazards as early as possible. To this end it maintains its Biological Effects Policy Advisory Group on low-level electromagnetic fields (BEPAG).

BEPAG has concluded that the balance of scientific evidence to date still does not indicate that harmful effects occur in humans due to low-level exposure to Electro-magnetic frequencies. This conclusion remains the same as that reached in its previous position statements, the last being in May 2006, and has not been substantially altered by the peer-reviewed literature published in the past two years.

BEPAG regards the replication of experimental studies as essential in order to improve the quality of the existing literature at both low and high frequencies. It recommends that isolated reports of biological effects or epidemiological findings should be treated with caution, until confirmed by independent groups.

In summary, the absence of robust new evidence of harmful effects of EMFs in the past two years is reassuring and is consistent with findings over the past decade. The public availability of electricity and the widespread use of telecommunications both have many demonstrable benefits to society, including health benefits. BEPAG is of the opinion that these factors, along with the overall scientific evidence, should be taken into account by policy makers when considering the costs and benefits of both the implementation of precautionary approaches to public exposure and also in the development of exposure guidelines.
