Radiological protection - Minimum criteria for electron paramagnetic resonance (EPR) spectroscopy for retrospective dosimetry of ionizing radiation - Part 1: General principles (ISO 13304-1:2020)
The primary purpose of this document is to provide minimum acceptable criteria required to establish a procedure for retrospective dosimetry by electron paramagnetic resonance spectroscopy and to report the results.
The second purpose is to facilitate the comparison of measurements related to absorbed dose estimation obtained in different laboratories.
This document covers the determination of absorbed dose in the measured material. It does not cover the calculation of dose to organs or to the body. It covers measurements in both biological and inanimate samples, and specifically:
a) based on inanimate environmental materials like glass, plastics, clothing fabrics, saccharides, etc., usually made at X-band microwave frequencies (8 GHz to 12 GHz);
b) in vitro tooth enamel using concentrated enamel in a sample tube, usually employing X-band frequency, but higher frequencies are also being considered;
c) in vivo tooth dosimetry, currently using L-band (1 GHz to 2 GHz), but higher frequencies are also being considered;
d) in vitro nail dosimetry using nail clippings measured principally at X-band, but higher frequencies are also being considered;
e) in vivo nail dosimetry with the measurements made at X-band on the intact finger or toe;
f) in vitro measurements of bone, usually employing X-band frequency, but higher frequencies are also being considered.
For biological samples, in vitro measurements are carried out in samples after their removal from the person or animal and under laboratory conditions, whereas the measurements in vivo are carried out without sample removal and may take place under field conditions.
NOTE The dose referred to in this document is the absorbed dose of ionizing radiation in the measured materials.
Strahlenschutz - Mindestanforderungen an die Elektronenspinresonanz (EPR-Spektroskopie) für die retrospektive Dosimetrie ionisierender Strahlung - Teil 1: Allgemeine Grundsätze (ISO 13304-1:2020)
Der Hauptzweck dieses Dokuments besteht darin, annehmbare Mindestkriterien festzulegen, die erforderlich sind, um ein Verfahren für die retrospektive Dosimetrie mittels paramagnetischer Elektronenresonanzspektroskopie einzuführen und die Ergebnisse zu berichten.
Der zweite Zweck ist die Erleichterung des Vergleichs von Messungen zur Abschätzung der Energiedosis, die in verschiedenen Labors durchgeführt wurden.
Dieses Dokument behandelt die Bestimmung der Energiedosis im gemessenen Material. Die Berechnung der Dosis für die Organe oder den Körper wird nicht behandelt. Es umfasst Messungen an biologischen und unbelebten Proben und insbesondere:
a) auf der Grundlage von unbelebten Umweltmaterialien wie Glas, Kunststoffen, Kleidungsstoffen, Sacchariden usw., die in der Regel bei X Band-Mikrowellenfrequenzen (8 GHz bis 12 GHz) hergestellt werden;
b) in-vitro-Zahnschmelz unter Verwendung von konzentriertem Zahnschmelz in einem Probenröhrchen, in der Regel mit X Band-Frequenz, aber auch höhere Frequenzen werden in Betracht gezogen;
c) in-vivo-Zahndosimetrie, derzeit mit L Band (1 GHz bis 2 GHz), aber auch höhere Frequenzen werden in Betracht gezogen;
d) in-vitro-Nageldosimetrie unter Verwendung von Nagelabschnitten, die hauptsächlich im X Band gemessen werden, aber auch höhere Frequenzen werden in Betracht gezogen;
e) in-vivo-Nageldosimetrie mit den Messungen im X Band an einem intakten Finger oder Zeh;
f) in-vitro-Messungen von Knochen, in der Regel unter Verwendung von X Band-Frequenzen, aber auch höhere Frequenzen werden in Betracht gezogen.
Bei biologischen Proben werden in vitro-Messungen an Proben nach deren Entnahme von der Person oder dem Tier und unter Laborbedingungen durchgeführt, während die Messungen in vivo ohne Probenentnahme durchgeführt werden und unter Feldbedingungen erfolgen dürfen.
ANMERKUNG Die Dosis, auf die in diesem Dokument Bezug genommen wird, ist die Energiedosis der ionisierenden Strahlung in den gemessenen Materialien.
Radioprotection - Critères minimaux pour la spectroscopie par résonance paramagnétique électronique (RPE) pour la dosimétrie rétrospective des rayonnements ionisants - Partie 1: Principes généraux (ISO 13304-1:2020)
Le but principal du présent document est de fournir un ensemble de critères minimaux acceptables requis pour établir un mode opératoire pour la dosimétrie rétrospective par spectroscopie par résonance paramagnétique électronique et pour présenter les résultats dans un rapport.
Son second objectif est de faciliter la comparaison des mesures associées à l'estimation de la dose absorbée de différents laboratoires.
Le présent document couvre la détermination de la dose absorbée dans le matériau mesuré. Il ne couvre pas le calcul de la dose délivrée aux organes ou à l'organisme entier. Il ne concerne que les mesurages de dosimétrie effectués sur des échantillons biologiques et des échantillons inertes, et plus particulièrement:
a) les mesurages de matériaux environnementaux inertes, tels que les verres, les polymères, les tissus pour vêtements, les saccharides, etc. généralement réalisés avec des fréquences micro‑ondes dans la bande X (8 GHz à 12 GHz);
b) les mesurages in vitro de prélèvement d'émail dentaire, placé dans un tube porte‑échantillon, et mesuré en général en bande X, mais des fréquences micro‑ondes plus élevées sont également considérées;
c) les mesurages in vivo de dents, réalisés actuellement en bande L (1 GHz à 2 GHz), mais des fréquences micro‑ondes plus élevées sont également considérées;
d) les mesurages in vitro de prélèvements d'ongles, effectués principalement en bande X, mais des fréquences micro‑ondes plus élevées sont également considérées;
e) les mesurages in vivo des ongles, effectués en bande X sur les ongles des doigts ou des orteils;
f) les mesurages in vitro de tissus osseux, réalisés en général en bande X, mais des fréquences micro‑ondes plus élevées sont également considérées.
En ce qui concerne les échantillons biologiques, les mesurages in vitro sont effectués sur des échantillons prélevés sur une personne ou un animal et dans des conditions de laboratoire, tandis que les mesurages in vivo sont réalisés sans prélèvement d'échantillon et peuvent s'effectuer sur le terrain.
NOTE La dose mentionnée dans le présent document est la dose absorbée de rayonnement ionisant dans les matériaux mesurés.
Radiološka zaščita - Minimalna merila za spektroskopijo z elektronsko paramagnetno resonanco (EPR) za retrospektivno dozimetrijo ionizirnega sevanja - 1. del: Splošna načela (ISO 13304-1:2020)
Glavni namen tega dokumenta je podati minimalna merila sprejemljivosti, ki so potrebna za vzpostavitev postopka za retrospektivno dozimetrijo s spektroskopijo z elektronsko paramagnetno resonanco in za poročanje rezultatov.
Namen je tudi olajšanje primerjave meritev v zvezi z oceno absorbirane doze, pridobljenih v drugih laboratorijih.
Ta dokument obravnava določevanje absorbirane doze v izmerjenem materialu. Ne obravnava izračuna doze, ki jo prejmejo organi ali telo. Zajema meritve tako v bioloških kot neživih vzorcih, zlasti:
a) na podlagi neživih okoljskih materialov, kot so steklo, plastika, tkanine, saharidi itd., ki so običajno izdelani pri mikrovalovnih frekvencah v pasu X (8 GHz do 12 GHz);
b) za meritve zobne sklenine in vitro z uporabo koncentrirane sklenine v tubi za vzorce, običajno pri frekvenci v pasu X, vendar so v obravnavi tudi višje frekvence;
c) za dozimetrijo zob in vivo, ki se trenutno izvaja v pasu L (1 GHz do 2 GHz), vendar so v obravnavi tudi višje frekvence;
d) za dozimetrijo nohtov in vitro z uporabo odrezkov nohtov, pri čemer se meritve izvajajo predvsem v pasu X, vendar so v obravnavi tudi višje frekvence;
e) za dozimetrijo nohtov in vivo z izvajanjem meritev v pasu X na nepoškodovanem prstu na roki ali nogi;
f) za meritve kosti in vitro, običajno pri frekvenci v pasu X, vendar so v obravnavi tudi višje frekvence.
Pri bioloških vzorcih se meritve in vitro izvajajo na vzorcih po njihovem odvzemu od osebe ali živali in v laboratorijskih pogojih, medtem ko se meritve in vivo izvajajo brez odvzema vzorca ter lahko potekajo na terenu.
OPOMBA: Doza, navedena v tem dokumentu, je absorbirana doza ionizirnega sevanja v izmerjenem materialu.
