liquid scintillation counting
LSC
  • katsematerjali radioaktiivsuse mõõtmine, mille korral kasutatakse meetodit, mille puhul segatakse radioaktiivne materjal vedela stsintillaatoriga (nt tsinksulfiidiga) ja loendatakse saadud footonite heitkogus/-arv
  • measurement of radioactive activity of a sample material which uses the technique of mixing the active material with a liquid scintillator (e.g. zinc sulfide), and counting the resultant photon emissions
vedelikuvälgatuste loendamine
Usage examples
  • Vedelikuvälgatuste loendamine (LSC) on standardne laboratoorne meetod madala energiaga radioisotoopide, enamasti beeta- ja alfakiirgust kiirgavate isotoopide radioaktiivsuse kvantifitseerimiseks. Tundlik LSC nõuab spetsiifilisi kokteile/vedelsegusid, mis neelavad energia tuvastatavateks valgusimpulssideks. Tõhus vedelikuvälgatuste loendamine toimub stsintillaatoriga tihedas kokkupuutes, mille tõttu on tagatud alfa- või beetaosakeste tuvastamine.
LSC abbreviation
liquid scintillation counting
Usage examples
  • Liquid scintillation counting (LSC) is a standard laboratory method for quantifying the radioactivity of low-energy radioisotopes, primarily those that emit beta or alpha radiation. Sensitive LSC requires specific cocktails (liquid mixtures) that convert energy into detectable light pulses. Effective liquid scintillation counting relies on close contact with a scintillator, which ensures the detection of alpha or beta particles.
