Which option describes a factor that could compromise the accuracy of radiation measurements?

Incorrect temperature can significantly compromise the accuracy of radiation measurements because radiation detection devices often have specific operational parameters that include temperature ranges. If a device is used outside of its recommended temperature range, the sensitivity and response of the detectors may be affected, leading to erroneous readings. For example, extreme cold or heat can alter electronic components, impact the materials used in the detectors, and skew the device's calibration settings.

In contrast, routine calibration ensures that the device is regularly adjusted to provide accurate readings, quality control involves processes and procedures in place to maintain standards, and proper training of the operator ensures they understand how to use the equipment correctly. Each of these factors contributes to reliable radiation measurement, while incorrect temperature can directly impair the device's performance.
