300 times the sensitivity of air ionization chambers with the same active
volume size.
The LIC-body, electrodes and the liquid are all of low atomic number and
their density is close to unit. This implicates that the perturbation
of the radiation field by the detector is negligible at measurements in
water or tissue-like materials.
- Photon energy dependence:
The calibration factor Gy/C varies less than
+5% for absorbed dose
measurements in water and photon energies from 20 to 150 keV.
Negligible except for irradiation from the chambers’ rear end.
- Long-term stability in calibration factor Gy/C:
Better than
+ 1% over years.
Typically 10-50 fA. Depends on polarization voltage and the size and shape
of the ionization volume.
The chambers are sealed and can be immersed in water for hours without
any changes in leakage current or calibration factor.
The general recombination depends on liquid layer thickness, polarization
voltage and dose-rate. For practical applications it never needs to exceed
1%.
E.g. for chambers having 0,35-mm liquid layer thickness the general recombination
at 900 V polarization voltage is less than 1% when irradiated by a pulsed
accelerator radiation beam and a dose-rate of 5Gy/ min.
The calibration factor Gy/C increases 0.3% per Celsius-degree
