Electromagnetic radiation isn't emitted by transmitting equipment only. Magnetic or electric fields occur wherever voltages are present or current flows, such as in industry, for example. Employers must protect their staff from effects that may endanger health, by determining safe distances from emitting equipment, restricting access, and other protective measures. This requires that they measure the field exposure levels and evaluate them according to the applicable occupational health and safety standards. Narda has the equipment you need.
