SpectroTRACER – Spectrometric probe - Bertin Technologies


SpectroTRACER – Spectrometric probe

SpectroTRACER is a continuous operating measurement system for nuclide specific detection of even lowest level gamma contamination in air (SpectroTRACER-Air/Soil) and in liquids (SpectroTRACER-Aqua)

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 (2.5 W) enables stationary or mobile applications using battery back-up or solar supply. 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.

Accurate detection and identification of radionuclides:

  • The SpectroTRACER probe is a continuous measurement system for detecting lowest gamma radiation in air and on the ground (and in water thanks to SpectroTRACER Aqua) 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.

High autonomy:

  • Low power consumption allows stationary and mobile application (with battery backup or solar power supply).

Easy to deploy:

  • The compact mobile setup can be installed within a few minutes and is available with several wireless data transmission options.

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 tubes, up to 10 Sv/h).
