Water quality - Determination of the activity concentration of radionuclides - Method by high resolution gamma-ray spectrometry (ISO 10703:2007)

ISO 10703:2007 specifies a method for the simultaneous determination of the activity concentration of various radionuclides emitting gamma rays with energies between 40 keV and 2 MeV in water samples, by gamma‑ray spectrometry using germanium detectors with high energy resolution in combination with a multichannel analyser.

Qualité de l'eau - Détermination de l'activité volumique des radionucléides - Méthode par spectrométrie gamma à haute résolution (ISO 10703:2007)

L'ISO 10703:2007 présente une méthode de détermination simultanée des activités volumiques de différents radionucléides émetteurs de rayonnements gamma d'énergies comprises entre 40 keV et 2 MeV, dans les échantillons d'eau, par spectrométrie gamma en utilisant un détecteur de germanium de haute résolution couplé à un analyseur multicanal.

Kakovost vode - Določevanje koncentracije aktivnosti radionuklidov - Metoda z gama spektrometrijo visoke ločljivosti (ISO 10703:2007)

Ta mednarodni standard določa metodo za hkratno določanje koncentracije aktivnosti raznih radionuklidov, ki oddajajo gama žarke z energijo 40 keV < E < 2 MeV v vzorcih vode, prek gama spektrometrije z detektorji iz germanija z visoko energijsko ločljivostjo v kombinaciji z večkanalnim analizatorjem. OPOMBA Določanje koncentracije aktivnosti radionuklidov, ki oddajajo gama žarke z energijo, manjšo od 40 keV in večjo od 2 MeV je ravno tako mogoče v obsegu tega mednarodnega standarda, pod pogojem, da sta tako kalibracija merilnega sistema kot zaščita prilagojena temu namenu. Ta mednarodni standard vključuje postopke za kalibracijo energije, določanje občutljivosti merilnega sistema, odvisne od energije, analizo spektrov in določanje koncentracije aktivnosti raznih radionuklidov v proučevanem vzorcu. Uporablja se samo za homogene vzorce. Vzorce z aktivnostmi, ki običajno znašajo med 1 Bq in 104 Bq je mogoče meriti kot take, tj. brez redčenja ali zgoščevanja vzorca ali posebnih (elektronskih) naprav. Odvisno od različnih dejavnikov, kot so energija gama žarkov in verjetnost emisij glede na jedrsko razpadanje, velikost in oblika vzorca in detektorja, zaščita, čas štetja in drugi parametri pri poskusu, naj bi bil vzorec zgoščen z izhlapevanjem, kadar je treba meriti aktivnosti pod približno 1 Bq. Kadar je aktivnost bistveno višja od 104 Bq, naj bi bil vzorec razredčen ali pa je treba izvleči preskusni delež vzorca, povečati razdaljo med virom in detektorjem ali uporabiti popravek za učinke kopičenja.
