Measurement of natural radioactivity in Jordanian sand

Measurement of natural radioactivity in Jordanian sand

Sand samples were collected from Adasiah (near Amman), Jerash and Ghor As-Safi (near Karak). 226Ra, 232Th and 40K activities, present in these samples, were measured using a gamma ray spectroscopy technique. The average values of the radium equivalent activities were calculated and were found to be...

Zusammenfassung:Sand samples were collected from Adasiah (near Amman), Jerash and Ghor As-Safi (near Karak). 226Ra, 232Th and 40K activities, present in these samples, were measured using a gamma ray spectroscopy technique. The average values of the radium equivalent activities were calculated and were found to be 41.06 Bq kg −1, 54.7 Bq kg −1 and 85.53 Bq kg −1 in samples collected from Adasiah, Jerash and Ghor As-Safi, respectively. These values are within the limit (i.e. less than 370 Bq kg −1) recommended for the safe use of construction materials for dwellingsby OECD.
