射线危害：低剂量的放射性射线辐射（天然背景
辐射的变化范围），对人体无害或风险甚低，
但达到一定剂量则会对人体有害，可引起癌症、
白内障、不孕症、突变、效应、寿命减短,
甚至死亡

The Inspector EXP
External Probe Surface Contamination Monitor

The Inspector EXP is designed to meet the requirements of emergency response personnel. It has the same valuable features, small size, and quality of the Inspector, but instead of the built-in detector, it has the added versatility of an external probe.

The carrying case has a clear window panel that provides a full view of the readout and count light and access to the switches. It includes convenient hａnd straps and a belt loop for carrying the instrument and a small pocket for a check source.

The probe can be attached to the carrying case for one-handed operation if desired. The protective probe cover folds easily out of the way during one-handed operation.
