We suggest different methods to define the origin of the problems in relation with criticality obtained from measurement.
High frequency Electromagnetic field
We calculate safety distance from the sources and we give exposition limit time.
Low frequency Electromagnetic field
We give minimum security distance from the sources both in magnetic field and electric field. The removal of the operator from the critical sources is often the most simple countermeasure. In other cases, if there are critical conditions or unexpected interferences we analyse the source and its surrounding environment then we study the application of particular shields.
When there are high power ratings the study requests the design of electrical systems and the logistics arrangement of the equipment in the workplace.
