title: [Hygienic evaluation and the problems of standardization of magnetic fields with the frequency of 50 Hz].
abstract: It is established that some kinds of technological equipment are the sources of the magnetic fields with the frequency of 50 Hz, their biologic activity being identified. Hygienic classification and approaches to differentiated standardization of the above factor are suggested with account of time and energetic parameters.
