Average daily exposures
Type of worker Median** Range
Workers on the job:
Clerical workers without
computers 0.5 0.2 - 2.0
Clerical workers with
computers 1.2 0.5 - 4.5
Machinists 1.9 0.6 - 27.6
Electric line workers 2.5 0.5 - 34.8
Electricians 5.4 0.8 - 34.0
Welders 8.2 1.7 - 96.0
Workers off the job
(home, travel, etc.) 0.9 0.3 - 3.7
*Magnetic fields are often measured in gauss or milligauss (one thousandth of a gauss = 1 milligauss).
**The median is the middle measurement: half the workers have average daily exposures above this point and half below.
May 2000: Parents left confused after an official report, chaired by Sir William Stewart, then chairman of the National Radiological Protection Board (NRPB), concluded that there were no proven health risks associated with mobile phones but that children should minimise their use as a precaution.
Feb 2001: The Mobile Telecommunications and Health Research Programme (MTHR) set up to encourage further research into potential health hazards of handsets and masts.
May 2001: Research in America suggested children’s brains absorbed 50-70 per cent more radiation from handsets than adults because their skulls were smaller.
Oct 2004: Swedish research concluded that those who used mobiles for 10 years were almost twice as likely to develop an acoustic neuroma - a tumour on a nerve connecting the ear to the brain.
Jan 2005: Chairman of the Health Protection Agency advised parents not to allow children under nine to use mobiles because of potential but unproven risks.
Dec 2006: A Danish study of people with brain tumours concluded there were no increased risks for heavy users.
Jan 2007: A study in Finland of people with nervous system tumours called gliomas found no link with mobile use until it separated out long-term, regular users. It was concluded that they were 39 per cent more likely to get a glioma on the side of their head where they held their handset.
Sept 2007: MTHR expected to present final report, including results of several unpublished studies. Prof Lawrie Challis, the chairman, expected to say there are no proven risks from short-term use, but to announce large-scale monitoring of health of handset users over 10 years.

Abstract:The article focuses on the report released by the American Institute of Stress that concerns on the effect of cell phones and electro-smog to human health. The European Environment Agency has advised teenagers under 18 years of age to avoid the use of wireless fidelity (Wi-Fi) and cell phones, while Israel has banned cellular antennas on residential buildings. However, the U.S. Food and Drug Administration (USFDA) has ensured that there is no evidence of danger to users of wireless phones.
