SARA – AUTONOMOUS SPECTROSCOPIC STATION AGS71xS/M
The SARA Autonomous Spectroscopic Station AGS710S/M / AGS711S/M is a radiation monitoring station which combines both
spectroscopic gamma detection with data logging capabilities and autonomous operation due to solar power supply and wireless data
transmission. Data communication between the AGS710S/M / AGS711S/M and Network Monitoring Center (NMC) uses the GPRS
service of cellular networks through a secure VPN. Two models are available: the AGS71xS for stationary use is designed for fixed
installation and unlimited operation that is achieved by the solar panel and a back-up battery. The mobile station AGS71xM can be
quickly deployed in case of emergency (battery-based temporary use). The station consists of a detector unit and a base unit. This
independency from any wired connections eases the installation of the station at any place of interest and permits simple relocation
if necessary. SARA is able to detect even minor changes of the composition of the nuclear spectra in the environment. This improves
significantly the recognition of artificial isotopes, which is very important for the radiation early warning system, for example. Not
only does it support the fast detection of artificial radiation but it can also identify the nuclear isotopes. It is designed for outdoor use
even in harsh environments and for continuous operation without any maintenance. The hermetically sealed detector unit
guarantees optimal protection for the detector and the electronics against environmental conditions. The NaI(Tl) -based scintillation
detector together with the MCA (multi-channel analyzer) provide high energy resolution under ambient temperature operation
conditions. The integrated embedded Linux-PC enables online isotope identification and versatile data exchange through several
interfaces. The standardized ANSI N42.42 protocol enables the use of many spectra evaluation software programs. The integrated
web server facilitates easy data access using a web browser. SARA also measures the gamma dose rate. For an extended gamma do se
rate range, the model AGS711S/M comes with an additional Geiger-Müller-detector (GM). Total gamma dose rate measurement of
SARA is calibrated according to Ambient Dose Equivalent Rate H*(10).
