# Instruments and apparatus for measuring or detecting ionizing radiations

## 1. Scope and Applicability

This PCR applies to the production of complete instruments and apparatus whose principal function is measuring or detecting ionizing radiation. Covered products include portable and installed radiation monitors, survey meters, dose or dose-rate meters, contamination monitors, counters, spectrometers, dosimeters, and radionuclide calibrators when supplied as complete instruments. The exact detector principle, radiation type, measured quantity, application class, and applicable performance standard are product qualifiers rather than separate PCR identities.

The foreground boundary covers receipt of purchased materials, components, detector assemblies, and subassemblies; in-house detector or sensor manufacture when performed; printed-circuit-board manufacture or assembly when performed; enclosure manufacture and surface finishing when performed; final assembly; software or firmware loading where integral to operation; calibration and performance verification; and packaging at the manufacturing site. Upstream production of purchased inputs is represented by linked upstream datasets.

Detector modules, sensor modules, bare detectors, replacement parts, accessories sold separately, ionizing-radiation sources sold as products, radiation-generating medical or industrial treatment equipment, and instruments whose principal function is measuring non-ionizing radiation are excluded as reference products. Use, maintenance, transport after the factory gate, and end-of-life treatment are outside the foreground manufacturing boundary and require separate scenario datasets when included in a life-cycle model.
