The natural γ-radiation in samples of a variety of marbles imported into Bangladesh for use in building construction was measured, employing γ-ray spectrometry with a HPGe detector. From the measured γ-ray spectra, activity concentrations were determined for 226Ra (29.31 ± 2.06 to 46.99 ± 2.97 Bq.kg...
