Doses received by the citizens living in Manisa due to these building materials were also calculated. The highest activity concentrations of 238U, 232Th and 40K found in the sand samples were 1559.10 Bq·kg-1, 142.48 Bq·kg-1 and 1711.47Bq·kg-1, respectively. The maximum mean of radium equivalent activity Raeq was 945 Bq·kg-1 calculated for levels in sand, gravel and stone samples. © 2006 SAGE Publications.Englishcementpotassium 40radioisotoperadiumthorium 232uranium 238articlebuilding materialconcentration (parameters)environmental radioactivitygamma radiationgamma spectrometrynatural radioactivitypriority journalradiation dosesandTurkey (republic)Article10.1177/1420326X06069059
