Comprehensive Guide to WHO Guidelines for Radon Testing in Drinking Water Laboratory Testing Service Provided by Eurolab
The World Health Organization (WHO) guidelines for radon testing in drinking water are based on the latest scientific research and data. The purpose of these guidelines is to provide a framework for laboratories to test drinking water for radon levels, ensuring public safety and health.
Relevant Standards
The following international and national standards govern the WHO Guidelines for Radon Testing in Drinking Water:
These standards outline the requirements for testing, sampling, and reporting radon levels in drinking water. They also provide guidelines for laboratory accreditation and certification.
Standard Development Organizations
The International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), European Committee for Standardization (CEN), and Turkish Standards Institution (TSE) are among the standard development organizations responsible for creating and updating these standards.
Why Standards Evolve
Standards evolve to reflect advances in technology, changes in regulatory requirements, or new scientific findings. For example, ISO 13140:2017 was revised in 2017 to improve the accuracy of radon measurements.
Standard Compliance Requirements
Industries requiring WHO Guidelines for Radon Testing in Drinking Water include:
These industries must comply with the relevant standards to ensure public safety and health. Compliance involves regular testing, reporting, and record-keeping.
Standard Numbers and Scope
Here are some standard numbers and their scope:
Standard Number Title Scope
--- --- ---
ISO 13140:2017 Radioactivity in water -- Measurement of radon-222 Specifies the requirements for measuring radon-222 in drinking water.
ASTM D5439-18 Standard Test Method for Determination of Radium in Drinking Water Outlines the procedure for determining radium levels in drinking water.
EN 16552-1:2014 Drinking water -- Radon-222 measurement methods -- Part 1: In-situ measurements Provides guidelines for measuring radon-222 in situ (in-place) in drinking water.
