A technique and results of experimental studies of geomagnetic field (GMF) induction in 195 different rooms in educational institutions, residential buildings, shopping malls and subway are presented. It is shown that in all the buildings there is weakening of the natural GMF. However, the GMF weakening is slight in the most areas and not dangerous to public health. Exceptions are areas of high-rise frame-cast-in-place residential blocks, offices and premises of shopping centers with steel frames and platforms of underground stations. Here, the GMF can be weakened to a dangerous level (less than 25 µT), which requires measures for its normalization.
