SpectroTRACER Air/Soil - Spectrometric probe

SpectroTRACER Air/Soil is a continuous operating measurement system for nuclide specific detection of even lowest level gamma contamination in air and on the ground.

The probe performs spectroscopic analysis of the measurement in order to identify the detected radionuclides. SpectroTRACER is used for radiation monitoring when a standard gamma dose rate monitor is not efficient enough and when it is required to qualify the nature of the gamma radiation.

The instrument is designed for operation under harsh conditions demanding minimum maintenance. Low power consumption enables stationary or mobile applications using battery back-up or solar supply.

The SpectroTRACER Air/Soil probe is a continuous measurement system for detecting lowest gamma radiation in air and on the ground  but also perfectly suited for high gamma radiation measurement, e.g. in emergency cases. It performs a spectrometric analysis of the measurement to identify the detected radionuclides. The device is suited to gamma monitoring whenever a pure gamma dose rate monitor is not efficient enough or for qualifying the nature of the gamma radiation.

The probe has a thermal protection of scintillator/PMT and is available with a Nal(Tl), a LaBr3(Ce) or CeBr3 Brillance detector, that allows different dose rate measuring range (according to IEC60846), different activity detection and identification of nuclides of artificial isotopes and natural background and different stability against temperature variations.

Low power consumption allows stationary and mobile application: up to 10 days of autonomy with battery back-up package or unlimited operation by solar power.

The compact mobile setup can be installed within a few minutes and is available with several wireless data transmission options. The options for data transmission include LAN, WIFI, 2G/3G/4G/LTE, Satellite or proprietary ShortLINK/SkyLINK radio. The latter is used for transmission of the ambient dose rate and the activity data of major nuclides.

All SpectroTRACER components are integrated into hermetically sealed housing allowing permanent and maintenance-free operation even under harsh conditions. The compact design of the probe includes: detector – HV – preamp – MCA – low power PC – LAN interface – Optional: GPS, wireless data transmission modules, GM module (two Geiger Muller tubes, up to 10 Sv/h).
