Radioactivity is related to energy that is released from radionuclides in the form of radiation. Ionizing radiation is produced as electromagnetic rays. These radiations are the cause of genetic, reproductive and cancerous effects in the living organisms.Because of the potential for radiation contamination in the food web to badly influence human and ecological well-being, and also the interest to understand the comparative influences of local and worldwide sources to present and upcoming radionuclide concentrations, many scientific efforts have been started to characterize radionuclides in...
