BS EN ISO 13162:2021

This standard BS EN ISO 13162:2021 Water quality. Carbon 14. Test method using liquid scintillation counting is classified in these ICS categories:

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

This document specifies a method for the measurement of ¹⁴C activity concentration in all types of water samples by liquid scintillation counting (LSC) either directly on the test sample or following a chemical separation.

The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater.

The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical recovery. The method described in this document, using currently available liquid scintillation counters and suitable technical conditions, has a detection limit as low as 1 Bq?l^?1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l^-1). ¹⁴C activity concentrations can be measured up to 10⁶ Bq?l^-1 without any sample dilution.

It is the user’s responsibility to ensure the validity of this test method for the water samples tested.
