Final answer:
Working with electromagnetic fields and installing antenna systems can be dangerous, with risks including exposure to non-ionizing radiation and physical dangers when maintaining high-voltage equipment. Health concerns have been raised, but non-ionizing radiation is generally considered less harmful. Managing radio wave interference is also an important part of this work.
Step-by-step explanation:
Working with electromagnetic fields (E-fields), along with repairing and installing antenna systems, presents potential hazards to personnel. These electromagnetic fields are often associated with power lines and high voltage equipment used to maintain the electrical power grid. Concerns about health hazards due to exposure to non-ionizing radiation from these power lines have been raised, although government environmental organizations consider this form of radiation to be less harmful than ionizing radiation.
Maintenance of power grids can involve working with high-voltage transformers and other equipment that pose risks, especially when removing animal carcasses that may cause damage. Additionally, professionals in this field must be aware of radio wave interference, which can be a significant issue as there is a need to manage the array of electromagnetic signals from various communication systems to prevent mutual disturbances.
