In this work, background radiation (absorbed dose rate) was
measured in the air of buildings in primary schools in Al-Najaf governorate,
Iraq using portable radiation dosimeter (Inspector Exp. USA). Annual average
dose (AED) and excess lifetime cancer risk (ELCR) were calculated in all
schools under study. Background radiation results were drawn using a
geographic information system (GIS) technique. The results show that, the
average values of dose rate (μSv/h) were 0.061±0.009. While, the average
values of AED (mSv/y) and ELCR were 0.049±0.007 and 0.188±0.03,
respectively. Statistically, the study proved the absence of any significant
factor (p-value > 0.05) between dose rate with type of school (baby and girls),
and any significant factor (p-value < 0.05) between dose rate with date of
establishment of schools. The levels of background radiation were found for all
schools in the present study and the Najaf city can be regarded as having
normal levels of background radiation which suggests that it does not pose any
health hazards or radiological effects for the inhabitants of the study area.
