The rice examined rice in this study is a major food in Iraq County. Recently, concerns hasve been raised about possible contamination of the crop by heavy metal. A large number of industrialized processes give rise to the contamination by heavy metals, such as cadmium (Cd), Iron (Fe) and lead (Pb) in soil, food, water, and air Almayahi et al., 2014a; Alduhaidahawi et al., 2015; Almayahi et al., 2016. The contaminants by heavy metals can be accumulated and transferred into rice. Fu et al. (2008) found the Pb with thea mean level of 0.69 ppm in polished rice in a typical electronic waste recycling area from the southeast China. Huang et al. (2009) observed thea high Pb concentration of 0.957 ppm in rice. Zhao et al. (2010) reported the Cd with a maximum value of 0.467 ppm in rice. These studies showed the possible contamination of rice by heavy metals. The Cd is toxic to the kidneys and has a long biological half-life in the human body. Pb has shown to be associated with damage to central nervous systems, and leads to the decrement of intelligence quotients in children. It is reasonable to hypothesize that the rice as thea staple foods of the humanity containing heavy metals has the potential health risks to consumers. In currecent years, there ishave been increasing environmental and global public health concerns associated with the environmental contamination by heavy metals. Human exposure has risen dramatically as a result of an exponential increase of its use in industrial, agricultural, domestic, and technological applications (Bradl, 2002). Environmental pollution is famwell knouswn in point source areas such as mining, foundries, smelters, and other metal-based industrial operations )(Fergusson, 1990; Bradl, 2002; He et al., 2005(). Natural uranium consists of three radioisotopes: 238U, 235U, and 234U with thea different half-life. The nucleus of radioactiveity is unstable, which means ingt is transformed to other elements either emitting or absorbing particles. The unstable nucleus loses energy by emitting ionizing particles for reaching a stable state. It undergoes alpha decay by radiating alpha particles (α) with decay energy (4.679 MeV). 4He is representing one alpha (α) particle. This radioactive substance can enter human bodies through ingestion of contaminated food or water, or inhalation.
