Custom radioactive standards to assess detector performance

Résumé

The field of CBRNE measurements presents many challenges and requires the development of advanced instrumentation. The Laboratoire National Henri Becquerel (http://www.lnhb.fr/) has the capabilities to manufacture custom radioactive standards, traceable according to ISO 17025. Our calibration certificates are recognized by our homologues [1] (NIST, NPL, etc.) and the laboratory has a comprehensive authorization for radionuclide use. If needed, we can recommend surrogate elements to match the emissions of rare or short-lived radionuclides. In addition to providing custom standards, we can help with their use to evaluate the performance of the RN prototypes being developed in terms of detection limits and linearity of the detector response. In addition, discrimination capabilities can be checked (emission interferences or even cross-talk between channels) via the measurement of radionuclide mixture. The standards manufactured can also be used to test the performance of signal processing algorithms in conditions close to field constraints. Our sources have been successfully used to test an original signal processing strategy based on artificial spiking neural networks to enable fast radionuclide identification at low count rate for radiological threats [2], or to test imaging systems for nuclear medicine needs [3]. The LNHB is ready to study what standards can be manufactured to enable a reliable performance assessment of advanced devices developed, or even to test them in our premises.
