Where should SRD and DLR be worn relative to the body?

• A. Behind the back
• B. On the hip only
• C. Front of the body between neck and waist, no more than a hand-width apart, facing away from the body
• D. On the head

Answer: (C)

Placing SRD and DLR on the front of the body, between the neck and the waist, with the two sensors no more than a hand-width apart and facing away from you, ensures your exposure is monitored where it’s most likely to come from and that the readings are consistent. Keeping them on the chest area in an outward-facing position gives the detectors a clear line of sight to ambient radiation while avoiding shielding by the body or clothing. This setup also keeps the devices easily accessible for readings. Positions behind the back, on the hip, or on the head would miss the typical exposure you’re guarding against and aren’t practical for accurate monitoring.
