BS EN ISO 13164-1:2020

This standard BS EN ISO 13164-1:2020 Water quality. Radon-222 is classified in these ICS categories:

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

This part of ISO 13164 gives general guidelines for sampling, packaging, and transporting of all kinds of water samples, for the measurement of the activity concentration of radon-222.

The test methods fall into two categories:

1. direct measurement of the water sample without any transfer of phase (see ISO 13164‑2 );

2. indirect measurement involving the transfer of the radon-222 from the aqueous phase to another phase (see ISO 13164‑3 ).

The test methods can be applied either in the laboratory or on site.

The laboratory is responsible for ensuring the suitability of the test method for the water samples tested.
