Introduction
This direct reading dosimeter is a ruggedly constructed precision instrument for measuring
and directly reading accumulated dose of gamma and X-ray radiation up to 2 mSv. Applications
include personal and environmental monitoring. The low-energy feature has hospital applications including
fluoroscopy, portable radiography, and angiography. A hardened sapphire end window provides clean,
scratch-proof viewing of measurements. This pocket sized instrument is lightweight and has a sturdy clip
to attach to an individual’s pocket for constant use.
