ABSTRACT
The study included measurements of electromagnetic radiation emitted by MACINTOSH PC placed in public schools, functional state examination of schoolchildren sitting in rows in front of PCs. Electromagnetic radiation emitted by PCs appeared to harm higher nervous activity of the schoolchildren. With consideration of the studies conducted the recommendation is not to set workplaces in rows. The workplaces could be set perimetrically, with at least 1.0 m between the lateral borders of neighboring monitors. Angle-wise set workplaces should stay at least 2.0 m apart.

Various kinds of works of 6-11th-form schoolchildren on Macintosh computers were physiologically and hygienically assessed at the lesson of information science and computer engineering (ISCE), as well as typing. The fatigue of a visual analyzer was due to the time of looking through the data available on the display; the adverse changes of the higher nervous activity depends on the complexity of educational materials and the intensity of work on a computer. Three-hour studies in ISCE should be excluded from the time able of lessons as they do not meet hygienic requirements.
