Water quality - Measurement of polonium 210 activity concentration in water by alpha spectrometry (ISO 13161:2011)

Water quality - Measurement of polonium 210 activity concentration in water by alpha spectrometry (ISO 13161:2011)

ISO 13161:2011 specifies the measurement of 210Po activity concentration by alpha spectrometry in all kinds of natural waters.
The detection limit of this method depends on the volume of the sample, the counting time, the background count rate and the detection efficiency. In the case of drinking water, the analysis is usually carried out on the raw sample, without filtration or other pretreatment.
If suspended material has to be removed or analysed, filtration at 0,45 µm is recommended. The analysis of the insoluble fraction requires a mineralization step that is not covered by ISO 13161:2011. In this case, the measurement is made on the different phases obtained. The final activity is the sum of all the measured activity concentrations.

Wasserbeschaffenheit - Bestimmung der Aktivitätskonzentration von Polonium-210 in Wasser mittels Alphaspektrometrie (ISO 13161:2011)

Qualité de l'eau - Mesurage de l'activité du polonium 210 dans l'eau par spectrométrie alpha (ISO 13161:2011)

L'ISO 13161:2011 spécifie le mesurage de l'activité du 210Po par spectrométrie alpha dans tout type d'eau naturelle.
La limite de détection de cette méthode dépend du volume de l'échantillon, du temps de comptage, du taux de comptage du bruit de fond et du rendement de détection. Dans le cas de l'eau potable, l'analyse s'effectue généralement sur l'échantillon brut n'ayant subi ni filtration, ni prétraitement.
S'il est nécessaire de séparer les matières en suspension ou de les analyser, une filtration à 0,45 µm est recommandée. L'analyse de la fraction insoluble nécessite une étape de minéralisation qui n'est pas couverte par l'ISO 13161:2011. Dans ce cas, le mesurage est effectué sur les différentes phases obtenues. L'activité finale est la somme de toutes les activités mesurées.

Kakovost vode - Merjenje koncentracije aktivnosti polonija Po-210 v vodi z alfa spektrometrijo (ISO 13161:2011)

Ta mednarodni standard določa merjenje koncentracije aktivnosti polonija Po-210 z alfa spektrometrijo v vseh vrstah naravnih vod. Meja detekcije te metode je odvisna od prostornine vzorca, časa štetja, stopnje štetja v ozadju in učinkovitosti zaznavanja. V primeru pitne vode se analiza običajno izvede na neobdelanem vzorcu brez filtracije ali druge predhodne obdelave. Če je treba suspendiran material odstraniti ali analizirati, se priporoča filtracija pri 0,45 μm. Za analizo netopnega deleža je potrebna faza mineralizacije, ki je ta mednarodni standard ne zajema (glej standard NF M 60-790-4[4]). V tem primeru se meritev izvede na različnih dobljenih fazah. Končna aktivnost je vsota vseh izmerjenih koncentracij aktivnosti.

Water quality - Lead-210 - Test method using liquid scintillation counting (ISO 13163:2021)
SIST EN ISO 13163:2022

This document specifies a method for the measurement of 210Pb in all types of waters by liquid scintillation counting (LSC).
The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample is necessary. Lead‑210 activity concentration in the environment can vary and usually ranges from 2 mBq l-1 to 300 mBq l-1 [27][28].
Using currently available liquid scintillation counters, the limit of detection of this method for 210Pb is generally of the order of 20 mBq l-1 to 50 mBq l-1, which is lower than the WHO criteria for safe consumption of drinking water (100 mBq l−1).[4][6] These values can be achieved with a counting time between 180 min and 720 min for a sample volume from 0,5 l to 1,5 l. Higher activity concentrations can be measured by either diluting the sample or using smaller sample aliquots or both. The method presented in this document is not intended for the determination of an ultra-trace amount of 210Pb.
The range of application depends on the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency).
The method described in this document is applicable to an emergency situation.
The analysis of Pb adsorbed to suspended matter is not covered by this method.
It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Water quality - Strontium 90 and strontium 89 - Test methods using liquid scintillation counting or proportional counting (ISO 13160:2021)
SIST EN ISO 13160:2021

This document specifies conditions for the determination of 90Sr and 89Sr activity concentration in samples of environmental water using liquid scintillation counting (LSC) or proportional counting (PC).
The method is applicable to test samples of drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample and a chemical separation are required to separate and purify strontium from a test portion of the sample.
The detection limit depends on the sample volume, the instrument used, the sample count time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available LSC counters, has a detection limit of approximately 10 mBq l−1 and 2 mBq l−1 for 89Sr and 90Sr, respectively, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[3]. These values can be achieved with a counting time of 1 000 min for a sample volume of 2 l.
The methods described in this document are applicable in the event of an emergency situation. When fallout occurs following a nuclear accident, the contribution of 89Sr to the total amount of radioactive strontium is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr.
The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method.
It is the user’s responsibility to ensure the validity of this test method selected for the water samples tested.

Water quality - Gamma-ray emitting radionuclides - Test method using high resolution gamma-ray spectrometry (ISO 10703:2021)
SIST EN ISO 10703:2021

This document specifies a method for the physical pre-treatment and conditioning of water samples and the determination of the activity concentration of various radionuclides emitting gamma-rays with energies between 40 keV and 2 MeV, by gamma‑ray spectrometry according to the generic test method described in ISO 20042.
The method is applicable to test samples of drinking water, rainwater, surface and ground water as well as cooling water, industrial water, domestic and industrial wastewater after proper sampling, sample handling, and test sample preparation (filtration when necessary and taking into account the amount of dissolved material in the water). This method is only applicable to homogeneous samples or samples which are homogeneous via timely filtration.
The lowest limit that can be measured without concentration of the sample or by using only passive shield of the detection system is about 5·10-2 Bq/l for e.g. 137Cs.1 The upper limit of the activity corresponds to a dead time of 10 %. Higher dead times may be used but evidence of the accuracy of the dead-time correction is required.
Depending on different factors, such as the energy of the gamma-rays, the emission probability per nuclear disintegration, the size and geometry of the sample and the detector, the shielding, the counting time and other experimental parameters, the sample may require to be concentrated by evaporation if activities below 5·10-2 Bq/l need to be measured. However, volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation.
This method is suitable for application in emergency situations.

This document specifies a method for the measurement of 14C activity concentration in all types of water samples by liquid scintillation counting (LSC) either directly on the test sample or following a chemical separation.
The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater.
The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical recovery. The method described in this document, using currently available liquid scintillation counters and suitable technical conditions, has a detection limit as low as 1 Bq∙l−1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l-1). 14C activity concentrations can be measured up to 106 Bq∙l-1 without any sample dilution.

Water quality - Guidance for rapid radioactivity measurements in nuclear or radiological emergency situation (ISO 22017:2020)
SIST EN ISO 22017:2021

This document provides guidelines for testing laboratories wanting to use rapid test methods on water samples that may be contaminated following a nuclear or radiological emergency incident. In an emergency situation, consideration should be given to:
—     taking into account the specific context for the tests to be performed, e.g. a potentially high level of contamination;
—     using or adjusting, when possible, radioactivity test methods implemented during routine situations to obtain a result rapidly or, for tests not performed routinely, applying specific rapid test methods previously validated by the laboratory, e.g. for 89Sr determination;
—     preparing the test laboratory to measure a large number of potentially contaminated samples.
The aim of this document is to ensure decision makers have reliable results needed to take actions quickly and minimize the radiation dose to the public.
Measurements are performed in order to minimize the risk to the public by checking the quality of water supplies. For emergency situations, test results are often compared to operational intervention levels.
NOTE    Operational intervention levels (OILs) are derived from IAEA Safety Standards[8] or national authorities[9].
A key element of rapid analysis can be the use of routine methods but with a reduced turnaround time. The goal of these rapid measurements is often to check for unusual radioactivity levels in the test sample, to identify the radionuclides present and their activity concentration levels and to establish compliance of the water with intervention levels[10][11][12]. It should be noted that in such circumstances, validation parameters evaluated for routine use (e.g. reproducibility, precision, etc.) may not be applicable to the modified rapid method. However, due to the circumstances arising after an emergency, the modified method may still be fit-for-purpose although uncertainties associated with the test results need to be evaluated and may increase from routine analyses.
The first steps of the analytical approach are usually screening methods based on gross alpha and gross beta test methods (adaptation of ISO 10704 and ISO 11704) and gamma spectrometry (adaptation of ISO 20042, ISO 10703 and ISO 19581). Then, if required[13], test method standards for specific radionuclides (see Clause 2) are adapted and applied (for example, 90Sr measurement according to ISO 13160) as proposed in Annex A.
This document refers to published ISO documents. When appropriate, this document also refers to national standards or other publicly available documents.
Screening techniques that can be carried out directly in the field are not part of this document.

Water quality - Polonium 210 - Test method using alpha spectrometry (ISO 13161:2020)
SIST EN ISO 13161:2021

This document specifies a method for the measurement of 210Po in all types of waters by alpha spectrometry.
The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample may be required.
The detection limit depends on the sample volume, the instrument used, the counting time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available alpha spectrometry apparatus, has a detection limit of approximately 5 mBq l−1, which is lower than the WHO criteria for safe consumption of drinking water (100 mBq l−1). This value can be achieved with a counting time of 24 h for a sample volume of 500 ml.
The method described in this document is also applicable in an emergency situation.
The analysis of 210Po adsorbed to suspended matter in the sample is not covered by this method.
If suspended material has to be removed or analysed, filtration using a 0,45 μm filter is recommended. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document [13]. In this case, the measurement is made on the different phases obtained. The final activity is the sum of all the measured activity concentrations.
It is the user's responsibility to ensure the validity of this test method for the water samples tested.
