What does the Electronic Alarming Dosimeter (EAD) do?

• A. Shows dose on a digital display and provides an audible alarm when limits are reached.
• B. Logs maintenance events in the plant computer.
• C. Displays ambient temperature readings only.
• D. Shows dose trends on a satellite feed.

Answer: (D)

The key idea here is remote monitoring of radiation dose. An Electronic Alarming Dosimeter is used not just to measure dose locally, but to feed dose information to the plant’s central monitoring systems so managers can see how exposure evolves over time. Showing dose trends on a satellite feed means the device transmits data to a remote or centralized receiver, allowing real-time or near-real-time trend analysis across workers and areas. This capability is vital for spotting rising exposure patterns early, coordinating protective actions, and supporting safety oversight. While many dosimeters provide a local numeric dose reading and may trigger an audible alarm, the standout feature in this context is remote trend visualization. Other options describe functions like logging maintenance events or displaying ambient temperature, which aren’t about tracking dose trends remotely.
