Hypogeomagnetic field in residential and public buildings

Introduction. The impact of geomagnetic field (GMF) on the human body is a proven fact, while an increased, but also a weakened geomagnetic field is the critical factor. The problems of normalization of GMF levels in existing residential and public buildings lead to the need for the use of calculation methods at the design stage of multistorey and high-rise buildings, the development of instrumental control methods at the stage of commissioning. The purpose of the study was to develop and scientifically substantiate methodological approaches to carrying out field measurements of GMF intensity and calculating the GMF attenuation coefficient in residential and public buildings. Materials and methods. The current and previously valid regulatory and methodological documents establishing requirements for geomagnetic field intensity measurements were analyzed, as well as protocols of GMF intensity measurement at thirty commissioned facilities completed in 2018–2022. Results. Issues arising during the measurements of GMF intensity and assessing hypogeomagnetic conditions in residential and public buildings are identified. The minimum required amount of work, control points of measurements, requirements to measuring instruments (MI), as well as to the processing and registration of the obtained measurement results are proposed. Limitations. The results of the study can be used only for measuring the GMF intensity and assessing hypogeomagnetic conditions in the premises of residential and public buildings, and are not applied to measurements in the workplace. Conclusion. The proposed methodological approaches will make it possible to carry out measurements of the geomagnetic field intensity, process and document the obtained results, as well as assess hypogeomagnetic conditions in residential and public buildings for compliance with current hygienic standards.
