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.

	* The 12ML01 mixture – ²⁴¹Am, ¹⁰⁹Cd, ¹³⁹Ce, ⁵⁷Co, ⁶⁰Co, ⁵¹Cr, ¹³⁷Cs, ¹¹³Sn, ⁵⁴Mn, ⁶⁵Zn, ⁸⁵Sr, ⁸⁸Y – generates around 15 peaks over an energy range from 60 keV to 1836 keV. The quantity of each radionuclide is chosen so that the counting rates of the main peak of each radionuclide are the same order of magnitude. Other geometries are available on request.
