Abstract
Biscuit is important type of food that is widely consumed by baby in Iraq and other countries.
This work measurers the natural radioactivity duo to long-lived gamma emitters in Children
biscuit by gamma spectroscopy, and estimates radiation hazard indices which are the radium
equivalent activity, the representative of gamma level index, the internal hazard index and
annual effective dose in children. Ten samples were collected from the Iraqi market for
different original countries. The average of specific activities for 226Ra, 232Th and 40K were
(9.390, 3.1213 and 214.969) Bq/kg respectively, but the average of the radium equivalent
activity and the internal hazard index were 33.101 Bq/kg and 0.107 respectively. The total
average of annual effective dose from consumption of adult, child and infant is estimated to
be 0.655, 1.009 and 0.875 mSv respectively. The values of specific activity, radiation hazard
indices and annual effective dose in all samples in this study are found lower than worldwide
median value for all groups, therefore theses values are found to be safe.
