The ALARA precautionary principle (As Low As Reasonably Possible) is the golden rule of radiation protection in the field of Risk Analysis science. This rule is applied to the exposure of individuals to radioactivity; this exposure must be low to be protected against health risks.
Prolonged exposure to high-level ionizing radiation, such as radon gas, can bring serious health risks, especially in the case of the ingestion of contaminated food or water.
This application note shows a measurement method of radon concentration in water using the Radon Exchange Module 1 (REM 1), a chemical-free system for air-water radon monitoring, developed by Bertin Instruments engineers.
