Radioactivity measurement using Liquid Scintillation techniques

Scintillateur liquide; liquid scintillator

Organic liquid with the property of emitting light after absorption of ionizing radiation.

Rayonnement ionisant; ionizing radiation

Radiation causing direct ionization of matter, consisting of electrons, photons of charged particles or ions.

Radionuclides; radionuclides

Radioactive atoms that disintegrate spontaneously, generally emitting ionizing radiation. Example tritium (³H), carbon-14 (¹⁴C), strontium-90 (⁹⁰Sr)...

Stallion; standard

Radioactive solution whose activity is traceable to national or international standards.

Light fading; quenching

Physico-chemical phenomena leading to the attenuation of light from a scintillator.

RCTD ; TDCR

Triple-to-double coincidence ratio method used in radionuclide metrology.

CIEMAT/NIST...
