[Hygienic regulation of static electric field generated by devices with electron-ray tube].

When detecting and hygienically assessing the static electric field generated by the devices with a half-tone storage tube it is necessary to take account of the impact of a number of characteristics of field intensity ranging on the obtained results. Taking into consideration the above characteristics during the research permits to lower error in the derived values and approximate them to the characteristics affecting the organisms of those using devices with a half-tone storage tube.

[Assessment of the health status of preschool children and of its determining factors].

A biomedical examination of preschool children inhabiting an industrial city showing contamination of the atmospheric air allowed to reveal changes of anthropometric data, bradycardia, hypertonia, increase of the minute volume, unfavourable type of mental capacity curve against the background of disturbed metabolic reactions. The above-mentioned changes may be considered as manifestations of the adaptative reaction of the body. It is rational to single out a contingent of high "risk" among children of the first health group.
