Passive neutron dosimetry systems - Part 1: Performance and test requirements for personal dosimetry (ISO 21909-1:2021)
This document provides performance and test requirements for determining the acceptability of
neutron dosimetry systems to be used for the measurement of personal dose equivalent, Hp(10), for
neutrons ranging in energy from thermal to 20 MeV1).
This document applies to all passive neutron detectors that can be used within a personal dosemeter
in part or in all of the above-mentioned neutron energy range. No distinction between the different
techniques available in the marketplace is made in the description of the tests. Only generic distinctions,
for instance, as disposable or reusable dosemeters, are considered.
This document describes type tests only. Type tests are made to assess the basic characteristics of the
dosimetry systems and are often ensured by recognized national laboratories
This document does not present performance tests for characterizing the degradation induced by the
following:
— intrinsic temporal variability of the quality of the dosemeter supplied by the manufacturer;
— intrinsic temporal variability of preparation treatments (before irradiation and/or before reading),
if existing;
— intrinsic temporal variability of reading process;
— degradation due to environmental effects on the preparation treatments, if existing;
— degradation due to environmental effects on the reading process.
Passive Dosimetriesysteme für Neutronenstrahlung - Teil 1: Leistungs- und Prüfanforderungen an die Personendosimetrie (ISO 21909-1:2021)
Dieses Dokument liefert Leistungs- und Prüfanforderungen zur Feststellung der Eignung von Neutronendosi¬metriesystemen für die Messung der Tiefen-Personendosis Hp(10) von Neutronenstrahlung im Energiebereich von thermischer Energie bis 20 MeV1.
Dieses Dokument gilt für alle passiven Neutronendetektoren, die ganz oder teilweise in dem oben genannten Neutronenenergiebereich als Personendosimeter eingesetzt werden können. Bei der Beschreibung der Prüf¬verfahren wird nicht zwischen den verschiedenen auf dem Markt verfügbaren Techniken unterschieden. Nur allgemeine Unterscheidungen wie z. B. Einwegdosimeter oder wiederverwendbare Dosimeter werden getrof¬fen.
Dieses Dokument beschreibt nur die Bauartprüfungen. Bauartprüfungen werden durchgeführt, um die grund¬legenden Eigenschaften der Dosimetriesysteme zu ermitteln und werden häufig von anerkannten, nationalen Laboratorien durchgeführt.
Dieses Dokument beschreibt keine Leistungsprüfungen, die der Ermittlung eines Leistungsabfalls aufgrund folgender Umstände dienen:
immanente zeitliche Schwankung der Qualität des vom Hersteller gelieferten Dosimeters;
– immanente zeitliche Schwankung der Vorbehandlung (vor der Bestrahlung und/oder vor dem Auslesen), soweit zutreffend;
– immanente zeitliche Schwankung des Ausleseprozesses;
– Verschlechterung aufgrund von Umgebungseinflüssen auf die vorbereitende Behandlung, soweit zutref¬fend;
– Verschlechterung aufgrund von Umgebungseinflüssen auf den Ausleseprozess.
Dieses Dokument enthält im Anhang C Informationen für die Teilkörperdosimetrie, basierend auf den Empfeh¬lungen des ICRU Report 66. Dieses Dokument befasst sich nur mit der Personendosimetrie bei Neutronen¬strahlung und nicht mit den Bedingungen eines Kritikalitätsunfalls.
Die Verknüpfungen zwischen diesem Dokument und ISO 21909-2 sind in Anhang A angegeben.
Systèmes dosimétriques passifs pour les neutrons - Partie 1: Exigences de fonctionnement et d'essai pour la dosimétrie individuelle (ISO 21909-1:2021)
Sistemi pasivne nevtronske dozimetrije - 1. del: Zahteve za delovanje in preskušanje za osebno dozimetrijo (ISO 21909-1:2021)
Ta dokument podaja zahteve za delovanje in preskušanje za ugotavljanje sprejemljivosti sistemov nevtronske dozimetrije, ki se uporabljajo za merjenje ekvivalentne osebne doze, Hp(10), za
nevtrone z različno energijo od toplotne do 20 MeV1.
Ta dokument se uporablja za vse pasivne detektorje nevtronov, ki se lahko v osebnem dozimetru uporabljajo
delno ali v celotnem navedenem energijskem območju nevtronov. V opisu preskusov se ne razlikuje med različnimi tehnikami, ki so na voljo na trgu. Upoštevana so le splošna razlikovanja, na primer dozimetri za enkratno ali večkratno uporabo.
Ta dokument samo opisuje tipske preskuse. Tipski preskusi se izvajajo za ocenjevanje osnovnih značilnosti dozimetričnih sistemov in jih pogosto zagotavljajo priznani nacionalni laboratoriji.
V tem dokumentu niso predstavljeni preskusi delovanja za karakterizacijo degradacije, ki jo povzročajo
naslednji dejavniki:
– lastna časovna spremenljivost kakovosti dozimetra, ki ga je dobavil proizvajalec;
– lastna časovna spremenljivost pripravljalnih postopkov (pred obsevanjem in/ali pred odčitavanjem),
če obstajajo;
– lastna časovna spremenljivost postopka odčitavanja;
– degradacija zaradi okoljskih vplivov na pripravljalne postopke, če obstajajo;
– degradacija zaradi okoljskih vplivov na postopek odčitavanja.
