COMPARING STANDARDS FOR GENERAL PUBLIC RF EXPOSURE LEVELS
(900 AND 1800 MHZ ARE THE TWO MAIN EXISTING UK MOBILE PHONE BANDS)
Prepared by Alasdair Philips, Technical Director, Powerwatch, June 2000
Multiple signals should be added together, as the square root of the sum of squares of the individual signals.
Figures in bold in the table below are the main units given in the guidance.
‘Near-field’ levels next to a working mobile phone handset vary enormously depending on the antenna design
but can often exceed the electric field and power density levels set in the general exposure standards.
