Abstract
Temporal and Spatial Analysis of Alpha and Beta Activity Concentration at Al-Tuwaitha Site, Baghdad
Highlights
In air near the surface, most of the radioactive materials at nuclear locations, nuclear weapons testing, or nuclear accidents are continuously emitting harmful ionizing radiations containing energetic charged particles such as alpha and beta
Knowledge of the radioactivity levels in the surface air of Al-Tuwaitha site is an important prerequisite for planning work areas and for anticipated future uses of the remediated site when inhaled or ingested (Chesser et al 2009)
Several local and international studies about the contaminated location for Al-Tuwaitha have been carried out by many Iraqi researchers. They investigated the radioactivity in analysing the different soil samples (Zaboon et al 2013, Jarjies et al 2013) taken from various places at the site and an assessment of radiation hazards for plants species growth (Mansour et al 2017)
Summary
In air near the surface, most of the radioactive materials (e.g. uranium and thorium series and the isotope of potassium) at nuclear locations, nuclear weapons testing, or nuclear accidents are continuously emitting harmful ionizing radiations containing energetic charged particles such as alpha and beta One of these common locations is Al-Tuwaitha nuclear research centre, which was used for nuclear activities, so contains significant amounts of radioactive materials. Several local and international studies about the contaminated location for Al-Tuwaitha have been carried out by many Iraqi researchers They investigated the radioactivity in analysing the different soil samples (Zaboon et al 2013, Jarjies et al 2013) taken from various places at the site and an assessment of radiation hazards for plants species growth (Mansour et al 2017). The purpose of this paper is to present the (1) spatial analysis of both AAC and BAC, (2) frequency distributions for specified intervals of these concentrations, (3) AAC and BAC roses, (4) daily variation during the study period, (5) comparison between AAC inside and outside of the studied site as well as for BAC, and (6) finding a simple empirical relation between AAC and BAC
