ISO - 13161

Water quality - Measurement of polonium 210 activity concentration in water by alpha spectrometry

inactive
Organization: ISO
Publication Date: 1 October 2011
Status: inactive
Page Count: 22
ICS Code (Examination of physical properties of water): 13.060.60
ICS Code (Radiation measurements): 17.240
scope:

This International Standard specifies the measurement of 210Po activity concentration by alpha spectrometry in all kinds of natural waters.

The detection limit of this method depends on the volume of the sample, the counting time, the background count rate and the detection efficiency. In the case of drinking water, the analysis is usually carried out on the raw sample, without filtration or other pretreatment.

If suspended material has to be removed or analysed, filtration at 0,45 μm is recommended. The analysis of the insoluble fraction requires a mineralization step that is not covered by this International Standard (see NF M 60-790-4[4]). In this case, the measurement is made on the different phases obtained. The final activity is the sum of all the measured activity concentrations.
