FIELD: medicine.SUBSTANCE: quantitative and qualitative characteristics of the HPF affecting workers is determined. A list of likely workers' NE exposed to the installed HPF is established. An observation group (OG), which workplaces are influenced by the HPF is formed. A comparison group (CG), the workplaces of which are not influenced by the HPF is formed.
