Radioactivity measurements in the aquatic environment using in-situ and laboratory gamma-ray spectrometry
G Eleftheriou, C Tsabaris, EG Androulakaki… - Applied Radiation and …, 2013 - Elsevier
The in-situ underwater gamma-ray spectrometry method is validated by inter-comparison
with laboratory method. Deployments of the spectrometer KATERINA on a submarine spring
and laboratory measurements of water samples with HPGe detector were performed.
Efficiency calibrations, Monte Carlo simulations and the Minimum Detectable Activity (MDA)
estimations were realized. MDAs varied from 0.19 to 10.4 (lab) and 0.05 to 0.35 (in-situ)
Bq/L, while activity concentrations differed from 7%(for radon progenies) up to 10%(for 40 …
