Features
Description
MoniRAD® Air Sampling is a air gamma radiation level measuring system able to works independently or in cooperation with MoniRAD® Area Measure.
The system monitors radioactive airborne levels in either working spaces, or via a process tubing connection to a remote stack, duct or other air space.
The system measure the air gamma level thanks to NaI scintillator placed in a Marinelli geometry container and a fast dedicated TTL counter.
The vacuum pump provide to put the air in the marinelly container by a multiplexer system that connect up to 8 locals (minimum 4 minute to complete single step).
