How close should the DCD be worn to the TLD badge?

Explanation:
The idea being tested is keeping dosimetry devices in close proximity so the measurements reflect the same exposure. If the DCD sits within about 15 cm of the TLD badge, they share essentially the same radiation environment, so the badge’s recorded dose accurately represents the wearer’s exposure. Moving the DCD farther away can introduce variation due to body shielding, geometry, and distance from the source, making readings less consistent and harder to correlate. So, place the DCD as close as practical to the TLD badge—within roughly 15 cm—to ensure the dose readings stay aligned during the shift.
