Water quality. Simultaneous determination of tritium and carbon 14 activities. Test method using liquid scintillation counting
水质 氚和碳14活度的同时测定 使用液体闪烁计数的试验方法
BS ISO 13168:2015 describes a test method for the simultaneous measurement of tritium and
carbon-14 in water samples by liquid scintillation counting of a source obtained by mixing the water
sample with a hydrophilic scintillation cocktail.This is considered a screening method because of the potential presence of interfering nuclides in
the test sample.The method can be used for any type of environmental study or monitoring.This International Standard is applicable to all types of waters having an activity concentration ranging
from 5 Bq/l to 106 Bq/l (upper limit of the liquid scintillation counters for direct counting). For higher
activity concentrations, the sample can be diluted to obtain a test sample within this range.Cross References:ISO 5667-1ISO 5667-3ISO 9698ISO 80000-10ISO 11929ISO/IEC Guide 98-3:2008GUM:1995ISO/IEC Guide 99:2007ISO 5667-14ISO 8258ISO/IEC 17025All current amendments available at time of purchase are included with the purchase of this document.
