When should an RF monitor be worn?

The choice of wearing an RF monitor in areas of unknown RF exposure is essential for safety and compliance with health regulations. RF monitors serve as a critical tool for detecting levels of radiofrequency radiation to which a technician may be exposed. When in an area where RF exposure is not well-defined or measured, it is crucial to use these monitors to ensure that exposure levels remain within safe limits.

In this context, unknown RF exposure signifies a potential risk, and having a monitor helps identify any hazardous conditions that could be present, thereby allowing technicians to take appropriate actions to protect themselves. This practice is rooted in ensuring occupational health and safety, as it helps mitigate risks associated with RF radiation, which can lead to adverse health effects if exposure exceeds established safety thresholds.

In areas of known RF exposure or during all operations, while it may be prudent to wear monitors, the key aspect of the correct answer lies in addressing situations where the safety levels are not clearly understood, thus emphasizing the need for caution and proactive measures.
