但達到一定劑量則會對人體有害，可引起癌癥、
白內(nèi)障、不孕癥、突變、萎縮效應(yīng)、壽命減短,
甚至死亡

參考信息（來自中國輻射防護研究院） 居民的劑量限值為每年1mSv。即0.114μSv/hr。 放射性職業(yè)人員劑量限值為每年20mSv，但任何一年不能超過50mSv。 
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.
