A Comparison of analytical methods used for determination of 235,238U and 210Pb from sediment samples by alpha, beta and gamma spectrometry

Aim of the study

The main aim was to compare analytical methods, radiochemical separation and gamma spectrometry, used for determination of 235,238U and 210Pb sediment samples. The usability of various analytical methods for 235,238U and 210Pb was estimated.

Implementation

In 2006, twelve sediment samples from Baltic Sea and twenty six samples from Red Sea were collected. The activity concentration of 235,238U was determined using gamma and alpha spectrometry. The activity concentration of 210Pb was determined using three different determination methods; alpha, beta and gamma spectrometry. In gamma spectrometry, the samples were analysed without sample digestion and in alpha and beta spectrometry after a radiochemical separation. The results were compared and statistical tests, an F-test and a t-test for paired samples, were used in the data evaluation.

Dissemination and exploitation of the results

The results are utilised in the measurement services, in the research projects carried out at STUK and in the development of STUK quality system.  An article in a scientific journal is written.
