TDSG3 spectroscopic gamma detector is designed for measuring ambient dose equivalent rate H*(10) in environmental conditions. TDSG3 is used to quickly evaluate the level of radiation in air. It is dedicated for early warning systems.
TDSG3 provides continuous and simultaneous dose rate measurement using Geiger-Müller tube and gamma spectrum using NaI(Tl) scintillation detector and 512-channels spectrum analyser.
The set is contained in a compact housing suited for Central Europe environmental conditions.
