The Government paid over $5000.00 for these radiation/dosimeter meters. You can pick on up for a fraction of that cost
Multi-functional survey instrument
The ADM-300 series of portable multi-functional survey instruments are rugged, reliable and designed for use in all environments. With built-in GM detectors, the ADM-300 will detect, measure, and digitally display both dose and dose rate levels of Gamma radiation from 10 μR/hr to 10,000 R/hr (0.1 μSv/hr to 100 Sv/hr) and Beta radiation from 10 μR/hr to 5 R/hr (0.1 μSv/hr to 0.05 Sv/hr). When coupled with optional external ‘smart’ probes, the ADM300 series of instruments can be used to measure, store, and display Alpha, Beta, Gamma, Neutron and X-ray radiation. ‘Smart’ probes store probe ID, calibration data and have an internal high voltage power supply.
This patented technique removes limitations such as dead time, coincidence loss, fold-over, and saturation in high fields associated with conventional GM detectors. This allows wide range detection with unsurpassed accuracy and linearity.
