Radiological protection - Sealed radioactive sources - General requirements and classification (ISO 2919:2012)

Radiological protection - Sealed radioactive sources - General requirements and classification (ISO 2919:2012)

ISO 2919:2012 establishes a classification system for sealed radioactive sources that is based on test performance and specifies general requirements, performance tests, production tests, marking and certification. It provides a set of tests by which manufacturers of sealed radioactive sources can evaluate the safety of their products in use and users of such sources can select types which are suitable for the required application, especially where protection against the release of radioactive material, with consequent exposure to ionizing radiation, is concerned. ISO 2919:2012 can also serve as guidance to regulating authorities.
The tests fall into several groups, including, for example, exposure to abnormally high and low temperatures and a variety of mechanical tests. Each test can be applied in several degrees of severity. The criterion of pass or fail depends on leakage of the contents of the sealed radioactive source.
Although ISO 2919:2012 classifies sealed sources by a variety of tests, it does not imply that a sealed source will maintain its integrity if used continuously at the rated classification. For example, a sealed source tested for 1 h at 600 °C might, or might not, maintain its integrity if used continuously at 600 °C.
A list of the main typical applications of sealed radioactive sources, with a suggested test schedule for each application, is given in Table 3. The tests constitute minimum requirements corresponding to the applications in the broadest sense. Factors to be considered for applications in especially severe conditions are listed in 4.2.
ISO 2919:2012 makes no attempt to classify the design of sources, their method of construction or their calibration in terms of the radiation emitted. Radioactive materials inside a nuclear reactor, including sealed sources and fuel elements, are not covered by ISO 2919:2012.

Strahlenschutz - Umschlossene radioaktive Stoffe - Allgemeine Anforderungen und Klassifikation (ISO 2919:2012)

Diese Internationale Norm legt für umschlossene radioaktive Stoffe (im Folgenden kurz als "Strahler" be-zeichnet) auf der Grundlage ihres Prüfverhaltens ein Klassifikationssystem fest und spezifiziert allgemeine Anforderungen, Belastbarkeitsprüfungen, Produktionsprüfungen, Kennzeichnung und Zertifizierung. Be-schrieben werden eine Reihe von Prüfungen, anhand derer der Hersteller von Strahlern die Sicherheit seiner Produkte im Gebrauch beurteilen kann und der Anwender der Strahler Typen auswählen kann, die für den jeweiligen Einsatz geeignet sind, insbesondere bezüglich des Schutzes vor einer möglichen Freisetzung ra-dioaktiven Materials und den daraus resultierenden Auswirkungen ionisierender Strahlung. Diese Internatio¬nale Norm kann auch als Leitlinie für Aufsichtsbehörden dienen.
Die Prüfungen sind in verschiedene Gruppen unterteilt, zu denen z. B. die Überprüfung der Auswirkungen ungewöhnlich hoher oder niedriger Temperaturen sowie eine Reihe mechanischer Prüfungen gehören. Jede Prüfung kann unter verschiedenen Graden der Beanspruchung ausgeführt werden. Die Erfüllung oder Nicht-erfüllung der Kriterien hängt von der Leckage von Inhaltsstoffen der Strahler ab.
ANMERKUNG   Dichtheitsprüfungen sind in ISO 9978 beschrieben.
Obgleich diese Norm Strahler nach verschiedenen Prüfungen klassifiziert, bedeutet dieses nicht, dass ein Strahler unversehrt bleibt, wenn er ständig den der angegebenen Klassifizierung entsprechenden Bedingun-gen ausgesetzt ist. Zum Beispiel kann ein für 1 h bei 600 °C geprüfter Strahler unversehrt bleiben oder auch nicht, wenn er ständig 600 °C ausgesetzt wird.
Eine Liste der typischen Hauptanwendungen von Strahlern mit einem empfohlenen Prüfplan für jede Anwen-dung ist in Tabelle 3 enthalten. Die Prüfungen entsprechen im weitesten Sinne den Minimalforderungen für die jeweiligen Anwendungen. Die für den Einsatz unter besonders schwierigen Bedingungen zu beachtenden Faktoren sind in 4.2 aufgeführt.
Mit dieser Internationalen Norm wird nicht beabsichtigt, die Gestaltung bzw. das Herstellungsverfahren sol¬cher Strahler oder deren Kalibrierung in Bezug auf die emittierte Strahlung festzulegen. Diese Internationale Norm gilt nicht für radioaktive Materialien im Innern von Kernreaktoren einschließlich dortiger umschlossener radioaktiver Stoffe und Brennelemente.

Radiološka zaščita - Zaprti radioaktivni viri - Splošne zahteve in razvrstitev (ISO 2919:2012)

Ta mednarodni standard določa sistem razvrstitve za zaprte radioaktivne vire, ki temelji na preskusni učinkovitosti, ter določa splošne zahteve, preskuse učinkovitosti, proizvodne preskuse, označevanje in certificiranje. Zagotavlja sklop preskusov, s katerimi lahko proizvajalci zaprtih radioaktivnih virov ocenijo varnost svojih proizvodov med uporabo, uporabniki teh virov pa lahko izberejo tipe, ki so primerni za potrebno uporabo, zlasti pri zaščiti pred sproščanjem radioaktivnega materiala s posledično izpostavljenostjo ionizirajočemu sevanju. Ta mednarodni standard lahko služi tudi kot navodila za upravne organe. Preskusi spadajo v več skupin, kot so na primer izpostavljenost izredno visokim in nizkim temperaturam ter različni mehanski preskusi. Vsak preskus se lahko izvede različno strogo. Merila za uspešno/neuspešno opravljen preskus so odvisna od puščanja vsebine zaprtega radioaktivnega vira. OPOMBA: Preskusne metode za puščanje so navedene v standardu ISO 9978. Čeprav ta mednarodni standard razvršča zaprte vire z različnimi preskusi, ne zagotavlja, da bo zaprt vir ohranil svojo celovitost, če se trajno uporablja pri naznačeni razvrstitvi. Na primer, zaprt vir, ki se eno uro preskuša pri temperaturi 600 °C, lahko ohrani svojo celovitost, če se trajno uporablja pri 600 °C, ali pa tudi ne. Seznam glavnih običajnih uporab zaprtih radioaktivnih virov s predlaganim preskusnim razporedom za vsako uporabo je podan v preglednici 3. Preskusi predstavljajo minimalne zahteve, ki ustrezajo uporabam v najširšem smislu. Dejavniki, ki jih je treba upoštevati za uporabe v zlasti strogih pogojih, so navedene v točki 4.2. Ta mednarodni standard ne poskuša razvrstiti zasnove virov, njihove metode izdelave ali njihovega umerjanja v zvezi z oddanim sevanjem. Radioaktivni materiali v jedrskem reaktorju, vključno z zaprtimi viri in gorivnimi elementi, niso obravnavani v tem mednarodnem standardu.

Passive neutron dosimetry systems - Part 2: Methodology and criteria for the qualification of personal dosimetry systems in workplaces (ISO 21909-2:2021)
SIST EN ISO 21909-2:2023

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.

Monitoring radioactive gases in effluents from facilities producing positron emitting radionuclides and radiopharmaceuticals (ISO 16640:2021)
SIST EN ISO 16640:2023

This document focuses on monitoring the activity concentrations of radioactive gases. They allow the calculation of the activity releases, in the gaseous effluent discharge from facilities producing positron emitting radionuclides and radiopharmaceuticals. Such facilities produce short-lived radionuclides used for medical purposes or research and can release gases typically including, but not limited to 18F, 11C, 15O and 13N. These facilities include accelerators, radiopharmacies, hospitals and universities. This document provides performance‑based criteria for the design and use of air monitoring equipment including probes, transport lines, sample monitoring instruments, and gas flow measuring methods. This document also provides information on monitoring program objectives, quality assurance, development of air monitoring control action levels, system optimisation and system performance verification.
The goal of achieving an unbiased measurement is accomplished either by direct (in-line) measurement on the exhaust stream or with samples extracted from the exhaust stream (bypass), provided that the radioactive gases are well mixed in the airstream. This document sets forth performance criteria and recommendations to assist in obtaining valid measurements.
NOTE 1 The criteria and recommendations of this document are aimed at monitoring which is conducted for regulatory compliance and system control. If existing air monitoring systems were not designed according to the performance criteria and recommendations of this document, an evaluation of the performance of the system is advised. If deficiencies are discovered based on a performance evaluation, a determination of the need for a system retrofit is to be made and corrective actions adopted where practicable.
NOTE 2 The criteria and recommendations of this document apply under both normal and off‑normal operating conditions, provided that these conditions do not include production of aerosols or vapours. If the normal and/or off-normal conditions produce aerosols and vapours, then the aerosol collection principles of ISO 2889 also apply.

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.

Evaluating the performance of continuous air monitors - Part 1: Air monitors based on accumulation sampling techniques (ISO/TR 22930-1:2020)
SIST-TP CEN ISO/TR 22930-1:2021

The use of a continuous air monitor (CAM) is mainly motivated by the need to be alerted quickly and in the most accurate way possible with an acceptable false alarm rate when a significant activity concentration value is exceeded, in order to take appropriate measures to reduce exposure of those involved.
The performance of this CAM does not only depend on the metrological aspect characterized by the decision threshold, the limit of detection and the measurement uncertainties but also on its dynamic capacity characterized by its response time as well as on the minimum detectable activity concentration corresponding to an acceptable false alarm rate.
The ideal performance is to have a minimum detectable activity concentration as low as possible associated with a very short response time, but unfortunately these two criteria are in opposition. It is therefore important that the CAM and the choice of the adjustment parameters and the alarm levels be in line with the radiation protection objectives.
The knowledge of a few factors is needed to interpret the response of a CAM and to select the appropriate CAM type and its operating parameters.
Among those factors, it is important to know the half-lives of the radionuclides involved, in order to select the appropriate detection system and its associated model of evaluation.
CAM using filter media accumulation sampling techniques are usually of two types:
a)    fixed filter;
b)    moving filter.
This document first describes the theory of operation of each CAM type i.e.:
—     the different models of evaluation considering short or long radionuclides half-lives values,
—     the dynamic behaviour and the determination of the response time.
In most case, CAM is used when radionuclides with important radiotoxicities are involved (small value of ALI). Those radionuclides have usually long half-life values.
Then the determination of the characteristic limits (decision threshold, detection limit, limits of the coverage interval) of a CAM is described by the use of long half-life models of evaluation.
Finally, a possible way to determine the minimum detectable activity concentration and the alarms setup is pointed out.
The annexes of this document show actual examples of CAM data which illustrate how to quantify the CAM performance by determining the response time, the characteristics limits, the minimum detectable activity concentration and the alarms setup.
