h) les annexes informatives contenant des exemples: d'instructions pour le client, de questionnaire, de rapport, d'ajustement de la courbe dose-réponse aux faibles doses par la méthode du maximum de vraisemblance et en tenant compte de l'erreur de l'estimation de dose, de méthode du rapport des odds pour les cas d'exposition suspectée à une faible dose, et de tableau type pour le dénombrement des aberrations chromosomiques.
Radiološka zaščita - Merila za delovanje laboratorijev, ki izvajajo biološko dozimetrijo s citogenetiko (ISO 19238:2014)
Standard ISO 19238:2014 določa merila za zagotavljanje in nadzor kakovosti, vrednotenje delovanja in akreditacijo biološke dozimetrije s pomočjo laboratorijev za storitve s področja citogenetike.
ISO 19238:2014 obravnava:
a) zaupnost osebnih podatkov naročnika in laboratorija, ki ponuja storitve;
b) zahteve za varnost laboratorija;
c) vire umerjanja in razpone odmerkov umerjanja, ki so koristni za določanje referenčnih krivulj učinkov odmerka za umerjanje, ki omogočajo ocenjevanje odmerka na podlagi frekvence kromosomskih aberacij in minimalnega razločljivega odmerka;
d) postopek ocenjevanja nestabilnih kromosomskih aberacij, ki se uporabljajo za biološko dozimetrijo;
e) merila za pretvorbo izmerjene frekvence aberacije v oceno absorbiranega odmerka;
f) poročanje o rezultatih;
h) zagotavljanje in nadzor kakovosti;
h) informativne dodatke, ki vsebujejo vzorčna navodila za kupca, vzorčni vprašalnik, vzorčno poročilo, primernost krivulje odziva na majhen odmerek z metodo največje verjetnosti ter izračun napake pri oceni razmerja obetov v primerih domnevne izpostavljenosti nizkemu odmerku in vzorec podatkovnega lista za beleženje aberacij.
