Product Name: Model Calibrator/M Semi-Automatic Calibration and Check Bench

Product Description

The Calibrator/M consists of:
A dosimeter handling and positioning conveyor drawer: 
A test slot allows positioning the dosimeter for exposure to the 137Cs control source.
A 137Cs source and its lead shield, designed as a collimator: 
Activity of the source of 137Cs – 1.11 MBq (30 ìCi).
The source is placed 3.5 cm (1.4 in.) from the DOSICARD’s detector.
Dose rate – 88 ìSv/h (8.8 mrem/hr).
Precision of the measurement – ±6%.
Irradiation time of the dosimeter – from four to 15 minutes (specified by the operator).
Note: The dose rate at the lead shield is <0.1 Gy/h (10 rad/h).
An electronic control device allowing: 
An input/output board ensures the control of the drawer as well as the position of the dosimeter test slot. The drawer has three pre-defined positions: 
Loading/Unloading of the DOSICARD (enables the operator to load or unload DOSICARDs into the calibration bench). 
Communication (sets the DOSICARD’s parameters before irradiation and analyzes the measurement results).
Irradiation (the DOSICARD is positioned for exposure to the control source during a length of time defined by the operator).

Features 
In order to ensure that the dosimeter (DOSICARD™) is operating correctly, a radiological calibration procedure must be carried out periodically (once a year) 
The calibration standard is the individual dose equivalent Hp(10) whose unit of measurement is the Sievert (Sv) 
The dosimeter is exposed to a beam of radiation for a few minutes with photons having a radiant energy of 662 keV (137Cs)
