BS EN ISO 9696:2017

This standard BS EN ISO 9696:2017 Water quality. Gross alpha activity. Test method using thick source 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 determination of gross alpha activity in non-saline waters for alpha-emitting radionuclides which are not volatile up to 350 °C.

The method is applicable to raw and potable waters.

The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter.

It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested.
