FH 41 B Multi-Purpose Radiation Meter
Hazardous gamma sources can appear at locations which are completely unexpected such as; in scrap yards, border crossings, and numerous public locations. Given today's orphan radioactive source problems there clearly is a need to monitor for radioactive sources in non-traditional locations.

The FH 41 B / FH 41 B-10 is designed to operate as both a stand-alone area monitor and as a fast responding survey meter.  

An area monitor and survey meter in a single unit.
