Beyond the catalog references, LEA can also produce tailored-made sources suited to your needs.
This feasibility study also helps defining the price and schedule associated with the requested supply. If the source is close to one of our catalog references, the completion time can be very short (a few weeks).
For more complex cases, requiring R&D and/or an LEA license upgrade, the time associated with the study and the necessary funding are then communicated to you for prior validation.
LEA proposes alpha and gamma multi-nuclides sources. LEA can also offer tailor-made multinuclides standards (from 3 to 12 nuclides). The percentage of each nuclide in the mixture can be specified by the customer. Default is the same activity for each radionuclide.
In terms of uncertainty, the COFRAC* scope defines the minimum level that LEA can provide under accreditation. If a COFRAC* certificate is not required, we may be able to offer reduced uncertainties; consult us for this.
Insofar that its manufacturing capabilities allow, LEA can offer tailor-made products with a reduced or asymmetrical manufacturing tolerance: for example, - 0% / 30% thus guaranteeing a minimum activity to ensure sufficient counting on your device, or conversely, -30% / -0% guaranteeing maximum activity to avoid saturating your measurement chains or remain in compliance with your material possession license.
Depending on the size of your detectors, a different active surface may be required for the standard source.
Sand, soil, cement, gas equivalents... we can study the production of tailor-made standards in matrices close to that which you require to control or characterize.
The solutions manufactured by LEA are provided according to a given chemical composition (particularly dilution and molarity). A specific medium can be offered as a tailor-made product at your request.
To produce sources with your specific bottles, 5 samples will be required for preliminary testing.
