Which device provides a digital dose reading and an audible alert when dose limits are reached?

• A. Self-Reading Dosimeter (SRD)
• B. Thermoluminescent Dosimeter (TLD)
• C. Optically Stimulated Luminescent Dosimeter (OSLD)
• D. Electronic Alarming Dosimeter (EAD)

Answer: (D)

Real-time dose monitoring with an audible warning is the capability being tested. An Electronic Alarming Dosimeter continuously measures radiation exposure and shows a digital dose reading on the device itself. It also has built-in alarms that sound when you reach or exceed preset dose limits, enabling immediate protective actions—like stopping work or moving away from the source. Passive dosimeters such as TLD and OSLD don’t provide immediate feedback and require lab readout after exposure to determine dose. A Self-Reading Dosimeter can display a dose on the device, but not all models include an audible alert linked to dose thresholds. Because the question specifies both a digital reading and an audible alert when dose limits are reached, the Electronic Alarming Dosimeter best fits that requirement.
