The paper presents the most significant actions which a primary Radionuclide Metrology Laboratory must accomplish, in order to disseminate the international equivalence to the entire national traceability chain: absolute standardization methods and demonstration of international equivalence, construction and calibration of a consistent set of secondary standardization equipment, preparation of radioactive standards. Delivery of radioactive standards to the end users and carrying out metrological services. Organization of national proficiency tests with the users. International validation of secondary standards by proficiency tests and establishment of a Quality System Assurance.

“…Many metrology laboratories have designed their own counters (e.g. Arenillas [97], Razdolescu [98], Zimmerman [99], Simpson [100], Cassette [81], Pochwalski [101]) but most of them use the specific coincidence module MAC3 designed by LNHB [102]. As the TDCR model assumes that the detection probability for one photon is not zero, the discriminator levels of these counters must be set to below the single electron response, which implies the use of high-gain photodetectors with a good peak-to-valley ratio on the single-photoelectron peak [103].…”

Radionuclide metrology using liquid scintillation counting

Liquid scintillation counting (LSC) techniques can be used for radionuclide standardization when the calculation of detection efficiency is possible. This is done using a model of the physicochemical processes involved in light emission and also of the statistics of photon emission: the free parameter model. This model can then be applied in two ways: by deducing the free parameter from the measurement of a tracer (the CIEMAT/NIST method) or by calculating this free parameter from coincidence ratio in a specific LS counter (the TDCR method). The purpose of this paper is to describe both these models and some practical issues that need to be addressed if LSC is to be effectively used in radionuclide metrology.
