Water quality — Radon-222 — Part 4: Test method using two-phase liquid scintillation counting
This document describes a test method for the determination of radon-222 (222Rn) activity concentration in non-saline waters by extraction and liquid scintillation counting.
The 222Rn activity concentrations, which can be measured by this test method utilizing currently available instruments, are above 0,5 Bq·l−1 which is the typical detection limit for a 10 ml test sample and a measuring time of…

Measurement of radioactivity in the environment — Guidelines for effective dose assessment using env...
These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality is performed to ensure the protection of human health[5][7][8][9][10][11][12]. The guidelines constitute a basis for the setting of national regulations, standards, and inter alia, for monitoring air, water and food in support of public…
Accuracy (trueness and precision) of measurement methods and results — Part 3: Intermediate precisio...
This document provides
a) a discussion of alternative experimental designs for the determination of trueness and precision measures including reproducibility, repeatability and selected measures of intermediate precision of a standard measurement method, including a review of the circumstances in which their use is necessary or beneficial, and guidance as to the interpretation and application…

Household and similar electrical air cleaning appliances — Methods for measuring the performance — P...
This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber.
Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors.
Air cleaners are used to reduce the…
Measurement of the radioactivity in the environment — Air: tritium — Test method using bubbler sampl...
This document describes a test method to determine the activity concentration of atmospheric tritium by trapping tritium in air by bubbling through a water solution. Atmospheric tritium activity concentration levels are expressed in becquerel per cubic metre (Bq∙m-3).
The formulae are given for a sampling system with four bubblers. They can also be applied to trapping systems with only one…
