Introduction. Wheat flour is a nutritious type of food
that is widely consumed by various age groups in Iraq. This
study investigates the presence of long-lived gamma
emitters in different type of wheat flour in Iraqi market.
Materials and methods. Uranium (
238
U), Thorium
(
232
Th) and Potassium (
40
K) specific activity in (Bq/kg) were
measured in (12) different types of wheat flours that are
available in Iraqi markets. The gamma spectrometry method
with a NaI(Tl) detector has been used for radiometric
measurements. Also in this study we have calculated the
internal hazard index, radium equivalent and absorbed dose
rate in all samples.
Results and discussion. It is found that the specific
activity in wheat flour samples were varied from
(1.086±0.0866) Bq/kg to (12.532±2.026) Bq/kg with an
average (6.6025) Bq/kg for
238
U, For
232
Th From
(0.126±0.066) Bq/kg to (4.298±0.388) Bq/kg with an
average (1.9465)Bq/kg and for
40
K from (41.842±5.875)
Bq/kg to (264.729±3.843) Bq/kg with an average (133.097)
Bq/kg. Also, it is found that the radium equivalent and the
internal hazard index in wheat flour samples ranged from
(3.4031) Bq/kg to (35.1523) Bq/kg with an average
(19.6346) Bq/kg and from (0.0091) to (0.1219) with an
average (0.0708) respectively.
Conclusion. This study prove that the natural
radioactivity and radiation hazard indices were lower than
the safe. |
