DIODE DOSE SENSORS
The Diode Dose Sensors feature:
Calibration Accuracy ± 4%, Energy Dependence and Filtration dependence: see below.
DDX6-W
The Diode Dose Sensor for Diagnostic range measurements
Energy dependence ± 5 %, 40-150 kV at 2.5 mm Al. Filtration
depe 5 % to -10 % for 2.5 to 23 mm Al.
DDX6-M
The Diode Dose Sensor for Mammographic range measurements
Energy dependence ± 5 %, 20-40 kV, 25-35 µm Mo. ± 5 % 25-35 kV 30
µm Mo + 2 mm Al. ± 10% 22-40 kV, 30 µm Mo + 2 mm AL.
Recommended for starter kit configuration.
Diode dose sensors
Diode sensors are compact, rugged, insensitive to handling, “instant-on” and do not require temperature
and pressure correction’ They are somewhat directional which reduces the effect of scatter. Their
energy response is not as uniform as the 10X6 ion chambers. Their directional response makes them
unsuitable for CT, scatter and leakage measurements. Temperature-dependent leakage current makes
them unsuitable for long-term dose measurements.
Accu-kV diode sensors (DDX10) are available that work in conjunction with an Accu-kV sensor. They
allow viewing radiation waveforms captured simultaneously with kV waveforms. They cannot make stand-
alone radiation measurements. (Discontinued
DDX6 diode sensors connect to the DD60 diode digitizer. They are standalone dose sensors providing a
full set of radiation measurements.
Relative dose:
The relative dose rate output is based on a single channel from the kV sensor. It is uncalibrated and
uncompensated, however it can serve as a measure of relative output for consistency tests and the
analog or USB waveform can assist in troubleshooting.
