Advanced Testing Methodology

The BS EN ISO 22908:2020 standard employs liquid scintillation counting, a sophisticated technique that enhances the accuracy of radium detection in water. This method is particularly effective for low-level radioactivity measurements, making it an invaluable tool for ensuring water safety and compliance with health regulations.

Why Choose Liquid Scintillation Counting?

Liquid scintillation counting is renowned for its sensitivity and precision, especially in detecting low-energy beta emitters like Radium 226 and Radium 228. This technique involves mixing a liquid sample with a scintillation cocktail, which emits light when interacting with radioactive particles. The emitted light is then measured, providing a direct indication of the radioactivity present in the sample.

Applications and Benefits

The BS EN ISO 22908:2020 standard is crucial for a wide range of applications, including:

• Environmental Monitoring: Ensure compliance with environmental regulations by accurately measuring radium levels in natural water bodies.
• Public Health: Protect public health by monitoring drinking water supplies for radioactive contamination.
• Industrial Applications: Assess the safety of water used in industrial processes, particularly in sectors like mining and oil extraction where radium contamination is a concern.

By adhering to this standard, organizations can demonstrate their commitment to maintaining high water quality standards and safeguarding public health.

• 13.060.60 Examination of physical properties of water
• 13.280 Radiation protection
• 17.240 Radiation measurements

This document specifies the determination of radium-226 (²²⁶Ra) and radium-228 (²²⁸Ra) activity concentrations in drinking water samples by chemical separation of radium and its measurement using liquid scintillation counting.

Massic activity concentrations of ²²⁶Ra and ²²⁸Ra which can be measured by this test method utilizing currently available liquid scintillation counters go down to 0,01 Bq/kg for ²²⁶Ra and 0,06 Bq/kg for ²²⁸Ra for a 0,5 kg sample mass and a 1 h counting time in a low background liquid scintillation counter^{[ 8]}.

The test method can be used for the fast detection of contamination of drinking water by radium in emergency situations.
