The present document, from which the results are derived of a VITO-study on order of LNE (department of Leefmilieu, Natuur en Energie of the Flemish Gouvernment) [1], deals with the exposure of the general public to the RF-radiation indoor produced by picocells in train stations and the national airport and outdoor produced by microcells in shopping streets of Belgian cities. The operating frequency of both cell types is 900 and 1800 MHz with weak low frequency components of 8.3 and 217 Hz respectively.
