As a result of this an increasing number of people is being exposed to the electromagnetic fields used for the data transfer between mobile telephones and base stations. This raises the question whether such exposure may result in negative health consequences. In September 1999 you and your colleague of Health, Welfare and Sport, also on behalf of the State Secretary of Transport, Public Works and Water Management, requested the Health Council to advise on this matter. A further official elaboration of this request indicated that in the short term especially advice was needed on GSM base stations, on behalf of the National Antennapolicy that is being formulated. On 9 March 2000 I have established the Electromagnetic Fields Committee that will report on the scientific developments with respect to exposure to such fields on a regular basis, initially for a period of four years. The first assignment of this committee was to formulate an advisory report on GSM base stations. Having consulted the Standing Committee on Radiation Hygiene I herewith present you with this report. The committee will now proceed to prepare a more general report on mobile telephony, in which also exposure to mobile telephones will be extensively dealth with. The committee will also anticipate in this report on new developments, such as the ‘third generation’ of mobile telephony, UMTS. Yours sincerely, (signed) Dr JA Knottnerus GSM base stations to the Minister of Housing, Spatial Planning and the Environment the Minister of Health, Welfare and Sport the State Secretary of Social Affairs and Employment the State Secretary of .
