Description

Users of the CANBERRA FC2B Calibrator can now field calibrate their own UltraRadiac units, saving both time and money. Like most electronic devices, the UltraRadiac requires periodic calibration to maintain proper function. UltraRadiac users may wish to avoid the cost associated with factory calibrations. These costs include:

• Shipment to and from the factory
• Down-time associated with not having the instrument readily available on-site
• Factory service charges

The CANBERRA FC2B Calibrator offers users the ability to calibrate their own UltraRadiacs without the costs and down-time typically associated with returning units to the factory.

The FC2B Calibrator is a low-level gamma radiation calibrator, which can be used to calibrate the UltraRadiac to an accuracy within ±20% of the true gamma dose rate. The FC2B Calibrator calibrates each unit very quickly – typically in less than three minutes.

The unit consists of an aluminum housing with a side opening and an internal checksource, 8 µCi of Cs-137. The opening positions the UltraRadiac correctly relative to the checksource.

A permanent Calibration Label on top of the Calibrator specifies the Calibration Set Point, representing the level of activity to which the UltraRadiac should be calibrated.

In addition, the Calibration Label specifies the checksource’s Date of Manufacture. Since the checksource decays at a mathematically predictable rate, the Date of Manufacture and the Decay Time Correction Table provided in the user’s manual together allow the user to correct for this decay over time, allowing the FC2B Calibrator to be used for many years.

The calibration routine is built into every UltraRadiac, which means that there’s no need for a PC and specialized software. All that’s needed to perform the calibration is the FC2B Calibrator and an UltraRadiac.
