Which radiation detection instrument measures the dose to a radiographer?

• A. Equipment survey device
• B. Environmental survey device
• C. Personal dosimetry device
• D. Handheld survey meter

Answer: (D)

The dose a radiographer receives is tracked with a personal dosimetry device worn on the body. This type of instrument is designed to accumulate and record the wearer’s radiation exposure over a period (shift or month), providing a numeric dose that can be compared to safety and regulatory limits. Handheld survey meters, by contrast, are used to measure ambient radiation levels at a moment in time or to check areas around equipment. They help assess current field strength and guide shielding or positioning decisions, but they do not quantify the cumulative dose a specific person has received. Equipment or environmental survey devices serve similar environmental-monitoring roles and don’t measure an individual’s dose. So, for determining the dose to a radiographer, a personal dosimetry device is the best choice.
