- •
An apparatus was developed to measure the radiocesium activity of contaminated soil.
- •
The unfolding method was used to determine the radioactivity.
- •
The method allows us to use the NaI(Tl) scintillator despite the overlap of peaks.
- •
Radioactivities measured with the apparatus and a HPGe detector agreed to within 9%.
