【 摘 要 】

Electromagnetic field levels at workplaces may exceed permissible limit values. In this case the individual protective means use obligatory. There are presented the date of typical samples of conductive suits (under work in power frequency electric field) testing by simulation and in experiment. Individual protective means screening factors were changed from 42.26 to 52.43 dB. The averaged electric field level inside of conductive suit was 220 mV/m in case of simulation. The induced electric fields in human body tissues with conductive suit were 0.003-0.150 V/m. The results show that conductive suit use allows reducing the induced electric filed levels and ensures worker safety.
