Abstract
Babies in Iraq and other nations frequently ingest biscuits, constituting a significant dietary group. In this work, gamma spectroscopy was used to assess long-lived gamma emitters in children's biscuits. Furthermore, radiation hazard indices, such as the yearly effective dose for children, the representative gamma level index, and the radium equivalent activity, were estimated. Ten examples were collected from the Iraqi market, representing a range of origins. The average specific activities for 238U, 232Th, and 40K were 11.174, 16.314, and 206.57 Bq/kg, respectively, but the internal hazard index and the average of the radium equivalent activity and the internal hazard index were 0.1662 and 50.382 Bq/kg, respectively. The total average annual effective dose from consumption by children and infants is estimated to be 1.47 and 1.2 mSv, respectively. All samples in this investigation had values for a specific activity, radiation hazard indices, and yearly effective dose that were lower than the global median values for all categories; as a result, these values were determined to be safe.
