Which of the following is a digital monitor that may be used to measure dose in an area?

• A. Handheld ionization chamber
• B. TLD
• C. Film badge
• D. Pocket ionization chamber

Answer: (A)

A handheld ionization chamber is an active device used for real-time radiation monitoring and typically provides a digital readout of dose rate and accumulated dose. This makes it suitable as a digital monitor for measuring dose in an area, since you can see the readings immediately and respond to changing conditions. In contrast, TLDs and film badges are passive dosimeters that integrate exposure over time and must be read out later to determine dose, not giving real-time feedback. Pocket ionization chambers offer quick readings but are not standard digital area monitors and are generally used for spot checks rather than continuous area monitoring.
