GAMMA-RAY SOIL MOISTURE SENSOR
HERMES CsI is designed to monitor a soil portion (i.e. footprint) in order to acquire gamma ray spectra to evaluate activity concentration of natural and artificial radionuclides, namely K-40, U-238, Th-232 and Cs-137 at natural background level.
HERMES CsI is an autonomous device, incuding:
- 2"×2" CsI(Tl) detector coupled to PMT
- MCA with HV power supply
- High-performance, low-consumption single board computer
- T, Rh and P sensors
- Router 3G/4G/WiFi/LAN
- Rugged technical case for long-term outdoor use
- HERMES-CsI Software
| | The device can also be coupled to an accessory solar power system through custom-made mechanical assemblies.
Data is stored in records containing energy-stabilized gamma ray spectra, together with count rate and activity concentration of each nuclide.
Measurement results are given in terms of Bq/g of K-40, U-238 and Th-232, as well as in terms of %K, ppm eU and ppm eTh.
The device is provided factory calibrated in energy. |
