Determination of long-lived gamma emitters in some vegetarian products in Al-Najaf governorate using NaI(Tl)

Abstract

Abstract In this study, gamma emitters including potassium-40, thorium-232, and uranium-238 were found in samples of 10 types of vegetarian products that were taken from various locations of Al-Najaf governorate. The experimental study is done by NaI(Tl) detectors that are produced by the ORTIC Analysis System. Also, some radiological risks due to these emitters as radium equivalent activity and internal hazard index were calculated using different theoretical equations. Given that all samples from Iraqi vegetarian products in the current study that tested for long-lived gamma emitters and risk factors for hazard were found to be below the global limit suggested by numerous organizations and commissions, one may conclude that there is no risk to human health from radiological hazard caused by gamma emitters.
