We are develop technology for neutron-gamma soil elemental analysis. Gamma detectors are the key equipment in this technology.
The main characteristics NaI and LaBr3 detectors are shown in the Table for comparison.
| Characteristic |
| NaI |
| LaBr3 |
| Energy resolution at 662 keV |
| 7 % |
| 2.6 % |
| Energy resolution at 4 MeV |
| 170 keV |
| 70 keV |
| Light yield |
| 38 photons/keV |
| 63 photons/keV |
| Density |
| 3.67 g/cm3 |
| 5.08 g/cm3 |
| Scintillation light decay constant |
| 250 ns |
| 26 ns |
As we can see from the table, using state-of-art LaBr3 detectors allow:
1. Decrease measurement time (in about 1.5 time).
2. Decrease minimal detectible level for soil carbon measurements in about 2 times.
3. Develop Associated Particle Imaging technique, which allow find soil element distribution by depth.
