Liquid sources

#{name}

Our liquid sources are mostly used in laboratories detection metrology purposes: calibration of detectors, periodic quality inspections such as control charts, periodic verification of detection performance.

The associated measurement systems are the devices used to control the discharge of liquid effluents into the environment: gamma spectrometry or liquid scintillation counting.

#{name}

The specific activity of our liquid sources is characterized by means of Nal scintillators, HPGe semi-conductors or liquid scintillation analyzers. They are calibrated under COFRAC* protocols. The measurement uncertainty varies between 1% and 8% depending on the radionuclide and the geometry.

* Scope N°2-6386 available on www.cofrac.fr or upon request.

Activities

The specific activity levels available as catalog reference are:

• 0. 001 μCi/g (0.04 kBq/g)

• 0.01 μCi/g (0.4 kBq/g)

• 1.1 μCi/g (40 kBq/g)

• 21.6 μCi/g (800 kBq/g)

• 261.2 μCi/g (8 000 kBq/g)

 

Standard geometries

• Ampoules

• V-Vial bottles

• Penicillin bottles

• Standardized bottles

Our liquid sources can be conditioned in other geometries offered in our catalog or provided by the customer.

How to compose the reference ?

Replace [Type] and [Act] with the letter and the value

according to the required geometry and activity.

For example, a 5ml ampoule (B type) containing 1.1 μCi/g

(40 kBq/g) of 137Cs is referenced as CS137 ELS B

40kBq/g.
