γ sources in resin matrix

#{name}

 

Radionuclides are incorporated into a thermosetting resin, which is then poured into container.

Our resin sources are sealed sources and are characterized by water equivalent activity, to avoid risks and constraints associated with liquid sources.

The radiological characteristics of the sources are measured with calibrated Nal scintillators or HPGe semi-conductors.

How to compose the reference ? 

Replace [Type] with the letter E, F, G, H, I, K, L, M or R according to the required geometry.  

For example: BA133 EGR E 15.

 

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

 

 

** 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.
