IRD 2000
Irradiator for Dosimeter Source Checking
This irradiator has been developed to be used by
dosimeters.
The IRD 2000 is used for periodic control in NPPs,
Defense departments...with a capability of up to 90
dosimeters (one irradiator) to 150 units (double irra-
diators) per hour. This tool is a standard production
unit.
The IRD 2000 has the  exibility to also use a Sr 90
source to check the beta response in the DMC
2000XB in addition to the standard gamma response
check.
FEATURES
Simultaneous checking of 3 or 6 dosimeters,
90 to 150 checks per hour.
Dosimeter source check or recalibration
Automatic operation:
- User operation limited to dosimeter insertion and removal
- Automated measurement acquisition
- Automated ef ciency calculation and load

Irradiator calibration results
Detail of irradiator dose rate reference setting using 3 Transfer-Standard dosimeters:
3 measurements are displayed per dosimeter for each reference position. The software checks the coherence of the reference dosimeter results and suggests a reference rate per position which is then accepted or rejected by the operator. The reference rate history and calibration details are saved.
Information common to dosimeter batch Reference dose rates reminder
Operator dialog box
Check results: the three dosimeters are within tolerances (here, 15 %)
