Описание (английский):

ISO 9696:2017 specifies a method for the determination of gross alpha activity in non-saline waters for alpha-emitting radionuclides which are not volatile up to 350 °C. The method is applicable to raw and potable waters. The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter. It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.

Overview

ISO 9696:2017 - Water quality - Gross alpha activity - Test method using thick source - specifies a laboratory method for measuring gross alpha activity in non-saline waters (raw and potable). The method targets alpha-emitting radionuclides that are not volatile up to 350 °C and uses a thick source preparation for radiometric counting. Applicability depends on the water’s total soluble salts and the counter’s background count rate and counting efficiency; it is the laboratory’s responsibility to verify suitability for each sample.

Key Topics and Requirements

Scope and limits: Applicable to raw and drinking waters but not to saline waters; radionuclides must be non-volatile up to 350 °C.

Sampling and handling: References ISO 5667 series for correct sampling, preservation and chain-of-custody practices.

Sample preparation stages: Detailed stages include pretreatment, concentration, sulfation, ignition, and source (planchet) preparation to produce a thick source suitable for alpha counting.

Measurement and calibration: Procedures for measurement, background determination, and preparation of a calibration source are specified to derive activity concentrations.

Performance metrics: Guidance on counting efficiency, background count rate, sensitivity and bias, and optimization of the determination for reliable results.

Quality checks: Contamination checks, including consideration of radon isotope and polonium losses during sample processing.

Data treatment: Methods for expressing results including calculation of activity concentration, standard uncertainty, decision threshold, detection limit, and confidence intervals (aligned with ISO 11929 and GUM principles).

Laboratory competence: Conformance with accreditation and quality system requirements (e.g., ISO/IEC 17025) and proper training/safety for staff.

Applications and Who Uses It

ISO 9696:2017 is used by:

Environmental and public health laboratories monitoring drinking water and raw water for radiological safety.

Wastewater and liquid effluent monitoring programs to verify compliance with national limits.

Water utilities and plant operators performing routine surveillance or emergency screening.

Regulatory agencies and accredited testing bodies assessing compliance with guidance levels (e.g., WHO screening levels such as 0.5 Bq·L⁻¹ for gross alpha).

Laboratories preparing for accreditation in radionuclide measurement.

Practical benefits include standardized gross alpha screening, reproducible results for regulatory compliance, and a clear framework for uncertainty and detection capability reporting.
