Georadis RT-50
Radiation Detection Monitor
The RT-50 is a state of the art gamma spectrum analyser which monitors and detects presence of radiation in metals, metals by-products, geological samples, construction materials, environmental commodities, food and many other materials. Floor standing and easy to operate, the RT-50 spectrum analyser is an indispensable part of any analytical laboratory, it rapidly detects and accurately measures extremely low levels of radioactive contamination. Used in such applications; Steel, scrap and other metal industries, geology and geophysics and the food and food processing industry.
