ActiveReference sources for the calibration of surface contamination monitors--Part 2:Electrons of energy less than 0.15MeV and photons of energy less than 1.5MeV
用于校准表面污染监测仪的参考源 第2部分:能量低于0.15MeV的电子和能量低于1.5MeV的光子
Application Summary AI generated
This standard specifies reference sources for calibrating surface contamination monitors used to detect low-energy electrons (below 0.15 MeV) and photons (below 1.5 MeV). It is applied in nuclear facilities, radiation protection, and environmental monitoring to ensure accurate measurement of surface contamination from beta and low-energy gamma emitters. The standard provides technical requirements for source construction, activity certification, and traceability to national metrology standards.
