Summary
This document specifies the methods and conditions for the determination of the activity concentration of 232Th in samples of environmental water (including seawater) and wastewater before their release into the environment, by alpha spectrometry and in using 229Th as a yield tracer. A chemical separation allows the thorium to be separated and purified from a test portion of the sample. The general principles described herein can be applied to the analysis of other alpha-emitting thorium isotopes such as 228Th and 230Th in aqueous samples.
