An electromagnetic pollution expert is a professional who studies, analyzes, and investigates the potential human and environmental risks of electromagnetic radiation emissions generated by the operation of electronic equipment and telecommunication signals.

To carry out these investigations and determine specific preventive actions, this expert employs various scientific methods and measurement technologies.

Among the areas of knowledge possessed by an expert in electromagnetic fields are the following:

• Electromagnets.
• Electricity.
• Mathematics.
• Electromagnetism.
• Consumer protection.
• Electromagnetic spectrum.
• Principles of Physics.
• Microwave principles.
• Engineering principles.
• Electrical engineering and electronic engineering.
• Regulations related to electrical equipment.
• Project blueprints.
• Environmental risks and threats.
• Environmental regulations.
• Principles of electricity.

Electromagnetic fields are commonly produced by transformer stations, medium and high voltage lines, electrical transformers, and everyday electrical equipment. An electromagnetic pollution expert typically works with various types of electromagnetic fields, which can be divided into several subclasses based on their physical characteristics of frequency and wavelength. Each of these fields will have associated energy ranges and therefore particular effects when interacting with matter.

Static electric fields: These are produced due to the presence of electric charges without any current. Any charge generates an electric field around it. These fields do not vary over time.

Static magnetic fields: These are generated by moving charges such as electric currents or permanent magnets.

Variable electromagnetic fields: These types of fields refer to time and radiation. They are generated by charges moving non-uniformly, with alternating current.

There are different types of variable electromagnetic fields:

• Extremely low-frequency fields: They fall within a frequency range of 3 Hz to 3 kHz and are typically produced by electrical distribution networks or electrical appliances operating at 50 Hz.
• Radiofrequency fields: Their frequency range fluctuates between 3 kHz and 300 MHz. Sources generating them include induction cooktops, arc welding equipment, and modulated broadcasting antennas, etc.
• High-frequency or microwave fields: Their frequency range extends from 300 MHz to 300 GHz. Some examples of electromagnetic pollution sources are traffic radars or microwave ovens.

Experts in electromagnetic fields provide measurement and diagnostic services for electromagnetic interference. Once they identify the source of the interference through measurements of the affected equipment's electromagnetic environment, they can propose solutions, which often involve relocating one of the devices or installing a protective shield around the emitting or affected equipment.
