It was established that, during the working shift, female transistor equipment assemblers were affected by periodic multiple short-term impulses of direct magnetic field (DMF) which was locally confined to the hand (with the field tension 35 kA/m at the finger-tips and 15 kA/m at the wrist). Local prenosologic manifestations were detected in females in the age group of up to 35 years with 1-10 years of length of work, which proved blood circulation vegetative disorders in upper extremities (arteriole-capillary vasoneurosis). A study of morbidity with temporary disability was made (at 100 cases per year ratio), which cindicated to markedly higher morbidity rate as compared to the sample group. The difference in morbidity rate between these two groups was accounted for by hypertensive vegetovascular disorders and 1-2 stages of HD. The data received necessitates the earliest norming of localized (limited to the hand) direct magnetic field influence.

The data on biologic effect of constant magnetic fields (CMF) of various intensity were presented. It was shown that animals (white rats) exposed to CMF of 1600-400 kA/m experienced moderately distinct functional changes, manifested by raising excitability of the CNS spinal sections, hypothermic reactions and variations in some blood indices. CMF of 80 kA/m and lower produced no unfavorable effect on animals. It was supposed to use the obtained data in the improvement of CMF hygienic standardization.
