Water quality — Measurement of gross alpha activity in non-saline water — Thick source method

95.99 Withdrawal of Standard 15 nën 2007

General information

Current stage: 95.99 Effective date: 15 nën 2007

Originator: ISO

Owner: ISO/TC 147

Type: International Standard

ICS: 13.060.60 13.280

Scope

The method is based on acidifying the sample to stabilize it, evaporation almost to dryness, conversion to the sulfate form and ignition at 350 °C, transfer of a portion of the residue to a planchette and counting alpha-activity in a alpha-particle detector. Covers non-volatile (at 350 °C) alpha-active radionuclides and can be extended to saline or mineralized waters, but with a reduced sensitivity. Applies to the analysis of raw and potable waters.
