[Hygienic assessment of priority physical factors of the urban dwelling environment]

A complex of chemical, physical, and biological factors of varying intensity influences man under the dwelling environmental conditions. Modern man spends as high as 80-90% of the day time under the conditions of the closed spaces of the urbanized habitat and is constantly exposed to physical factors. The present environmental hygiene monitoring system requires great attention to the control of priority physical factors in the environment. By using a number of examples, the authors give criteria for determining the priority of factors of physical nature and an objective assessment of their importance in the formation of the safe dwelling environment.
