Ground Level Hazard Emitters are defined as systems capable of producing power density levels at or above the MPE near ground level. This is the most hazardous and where exposures are expected. Which term fits this description?

Ground Level Hazard Emitters are defined as systems capable of producing power density levels at or above the MPE near ground level. This is the most hazardous and where exposures are expected. Which term fits this description?

• A. Upper Tier
• B. Non-Hazardous Exposures
• C. Lower Tier
• D. Ground Level Hazard Emitters

Answer: (D)

In non-ionizing radiation safety, exposure zones are defined by how the power density compares to the maximum permissible exposure (MPE). The scenario describes systems that can produce power density at or above the MPE right at ground level, where people are most likely to be exposed. That exact description corresponds to Ground Level Hazard Emitters, since it names the hazard at the height where exposures are greatest and meet or exceed the MPE. The other terms would refer to different hazard levels or locations (for example, lower or non-hazardous exposures) and don't specifically denote the ground-level, MPE-comparable hazard.
