The present investigation has studied the specific features of shielding of the natural geomagnetic field (GMF) in the multistorey apartment houses. The results of the experimental study of the shielding properties of some building materials are presented. It is shown that there are 1.2 to 2.0-fold reductions in GMF induction within the houses depending on the number of storeys and the properties of building materials. The level of GMF within the multistorey apartment house decreases by an average of 27.2+/-0.5 microTl from the 1st to the 9th floor and the GMF attenuation factor in many apartment houses exceeds the permissible limit for working places, especially on the top floors. On designing new building materials and constructions and on architectural design, one should keep in mind their shielding properties.
本研究探讨了多层公寓楼中自然地磁场（GMF）屏蔽的具体特征。给出了一些建筑材料屏蔽特性的实验研究结果。结果表明，根据楼层数和建筑材料的特性，房屋内的地磁场感应强度会降低1.2至2.0倍。多层公寓楼内的地磁场强度从1楼到9楼平均降低27.2±0.5微特斯拉，许多公寓楼的地磁场衰减系数超过了工作场所的允许限值，尤其是在顶层。在设计新型建筑材料和结构以及进行建筑设计时，应考虑它们的屏蔽特性。
