[Occupational health issues in the technologic application of direct magnetic fields in the production of...

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.
