Passive neutron dosimetry systems - Part 2: Methodology and criteria for the qualification of personal dosimetry systems in workplaces (ISO 21909-2:2021)
This document provides methodology and criteria to qualify the dosimetry system at workplaces where
it is used. The criteria in this document apply to dosimetry systems which do not meet the criteria with
regard to energy and direction dependent responses described in ISO 21909-1.
The qualification of the dosimetry system at workplace aims to demonstrate that:
— either, the non-conformity of the dosimetry system to some of the requirements on the energy or
direction dependent responses defined in ISO 21909-1 does not lead to significant discrepancies in
the dose determination for a certain workplace field;
— or, that the correction factor or function used for this specific studied workplace enables the
dosimetry system to accurately determine the conventional dose value with uncertainties similar
to the ones given in ISO 21909-1.
The methodologies to characterize the work place field in order to perform the qualification of the
dosimetry system are given in Annex A. Annex B is complementary as it gives the practical methods to
follow, once one methodology is chosen.
The provider of the dosimetry system shall provide the type test results corresponding to ISO 21909-1.
However, when the dosimetry system to be qualified does not comply with all the criteria of ISO 21909-1
dealing with the energy and angle dependence of the response, some tests of the ISO 21909-1 can be not
performed.
Passive Dosimetriesysteme für Neutronenstrahlung - Teil 2: Verfahren und Kriterien für die Qualifizierung von Personendosimetriesystemen an Arbeitsplätzen (ISO 21909-2:2021)
Dieses Dokument enthält Verfahren und Kriterien zur Qualifizierung des Dosimetriesystems an Arbeitsplätzen, an denen es eingesetzt wird. Die Kriterien in diesem Dokument gelten für Dosimetriesysteme, die die in ISO 21909-1 beschriebenen Kriterien hinsichtlich der Energie- und Richtungsabhängigkeit des Ansprechver¬mögens nicht erfüllen.
Die Qualifizierung des Dosimetriesystems am Arbeitsplatz zielt darauf ab, Folgendes nachzuweisen:
– entweder die Nichtübereinstimmung des Dosimetriesystems mit einigen der in ISO 21909-1 festgelegten Anforderungen an die Energie- oder Richtungsabhängigkeit des Ansprechvermögens führt nicht zu signi¬fikanten Diskrepanzen bei der Dosisbestimmung für ein bestimmtes Arbeitsfeld;
– oder der für diesen speziell untersuchten Arbeitsplatz verwendete Korrektionsfaktor bzw. die verwendete Korrektionsfunktion ermöglicht dem Dosimetriesystem, den richtigen Wert der Dosis genau zu bestimmen, mit ähnlichen Unsicherheiten, wie sie in ISO 21909-1 angegeben sind.
ANMERKUNG Dieses Dokument richtet sich an alle beteiligten Akteure: Personendosis-Messstellen (IMS, en: individual monitoring service), Akkreditierungs- oder Aufsichtsbehörden und Anwender der jeweiligen Dosimetrie (mit Anwender ist die Stelle gemeint, die das Dosimetriesystem der strahlenexponierten Arbeitskraft zuordnet und die zugeordnete Dosis aufzeichnet).
Die Verfahren zur Charakterisierung des Arbeitsplatzes im Hinblick auf die Qualifizierung des Dosimetriesys¬tems sind in Anhang A aufgeführt. Anhang B ist eine Ergänzung, da er die praktischen Verfahren enthält, die zu befolgen sind, sobald ein Verfahren gewählt wurde.
Der Anbieter des Dosimetriesystems muss die Ergebnisse der Bauartprüfung nach ISO 21909-1 vorlegen. Erfüllt das zu qualifizierende Dosimetriesystem nicht alle Kriterien der ISO 21909-1, die sich mit der Energie- und Winkelabhängigkeit des Ansprechvermögens befassen, können einige Prüfungen der ISO 21909-1 nicht durchgeführt werden.
Die Verknüpfungen zwischen ISO 21909-1 und ISO 21909-2 sind in Anhang E beschrieben.
Dieses Dokument bezieht sich ausschließlich auf die reguläre Personenüberwachung für Neutronenstrahlung und nicht auf die Bedingungen eines Kritikalitätsereignisses.
Systèmes dosimétriques passifs pour les neutrons - Partie 2: Méthodologie et critères de qualification des systèmes dosimétriques individuels aux postes de travail (ISO 21909-2:2021)
Sistemi pasivne nevtronske dozimetrije - 2. del: Metodologija in merila za kvalifikacijo osebnih dozimetričnih sistemov na delovnih mestih (ISO 21909-2:2021)
Ta dokument podaja metodologijo in merila za kvalifikacijo dozimetričnega sistema na delovnih mestih, kjer se uporablja. Merila iz tega dokumenta se uporabljajo za dozimetrične sisteme, ki ne izpolnjujejo meril glede odzivov, ki so opisani v standardu ISO 21909-1.
Cilj kvalifikacije dozimetričnega sistema na delovnem mestu je pokazati, da:
– dozimetrični sistem ni skladen z nekaterimi zahtevami glede odzivov, odvisnih od energije ali
smeri, ki so določeni v standardu ISO 21909-1, kar ne povzroča bistvenih neskladij pri
določanju doze za delovno mesto na določenem področju;
– ali pa lahko s korekcijskim faktorjem ali funkcijo, ki se uporablja za to določeno proučevano delovno mesto,
dozimetrični sistem natančno določi vrednost običajne doze z negotovostmi, ki so podobne
tistim iz standarda ISO 21909-1.
Metodologije za karakterizacijo področja delovnega mesta za izvedbo kvalifikacije
dozimetričnega sistema so podane v dodatku A. Dodatek B je dopolnilo, saj podaja praktične metode, ki jih je treba upoštevati ob izbiri katere od metodologij.
Ponudnik dozimetričnega sistema mora zagotoviti rezultate tipskega preskusa, ki ustrezajo standardu ISO 21909-1.
Kadar dozimetrični sistem za kvalifikacijo ne izpolnjuje vseh meril iz standarda ISO 21909-1, ki obravnava odvisnost odziva od energije in kota, nekateri preskusi iz standarda ISO 21909-1 niso mogoči.
