Özet

In this paper, we attempt to determine the activity concentration of natural and artificial radionuclides in 37 sand samples from the Mediterranean coast of Antalya in Turkey by using a high purity Germanium (HpGe) detector. U-238, Th-232, K-40 and Cs-137 activity concentrations, absorbed dose rate, annual effective dose equivalent, radium equivalent activity, external and internal hazard index of sand samples are determined respectively. The average values are 13.43 +/- 0.21 Bq/kg, 6.96 +/- 0.06 Bq/kg and, 122.46 +/- 18.58 Bq/kg, for U-238, Th-232 and K-40 respectively. Most of the activity concentration values are less than below minimum detection limit for Cs-137. The average values of the absorbed dose rate D (nGy/h), annual effective dose equivalent AEDE(mu Sv/y), radium equivalent activity Ra-eq (Bq/kg), external hazard index Hex and internal hazard index H-in are 15.52 nGy/h, 19.03 mu Sv/y, 32.81 Bq/kg, 0.09 and 0.12 respectively. It is observed that U-238, Th-232, K-40 and Cs-137 activity concentrations, absorbed dose rate, annual effective dose equivalent, radium equivalent activity are in the limit of the published values, external and internal hazard index values are less than unity.

In this paper, we attempt to determine the activity concentration
of natural and artificial radionuclides in 37 sand samples
from the Mediterranean coast of Antalya in Turkey by using a
high purity Germanium (HpGe) detector. 238U, 232Th, 40K and
137Cs activity concentrations, absorbed dose rate, annual effective
dose equivalent, radium equivalent activity, external and
internal hazard index of sand samples are determined respectively.
The average values are 13.43 ± 0.21 Bq/kg, 6.96 ±
0.06 Bq/kg and, 122.46 ± 18.58 Bq/kg, for 238U, 232Th and 40K
respectively. Most of the activity concentration values are less
than below minimum detection limit for 137Cs. The average values
of the absorbed dose rate D (nGy/h), annual effective dose
equivalent AEDE( lSv/y), radium equivalent activity Raeq
(Bq/kg), external hazard index Hex and internal hazard index
Hin are 15.52 nGy/h, 19.03 lSv/y, 32.81 Bq/kg, 0.09 and 0.12
respectively. It is observed that 238U, 232Th, 40K and 137Cs activity
concentrations, absorbed dose rate, annual effective dose
equivalent, radium equivalent activity are in the limit of the
published values, external and internal hazard index values
are less than unity.
