Due to the environmental and health problems of the use of chemicals in food preservation since the preparation of this study to contribute to improving the environmental and health status of the community through an economic study to establish food irradiation unit in the El-oubowr market for food wholesale trade as an alternative to chemical use. The study showed that potatoes, onions, garlic, orange, strawberries, mangoes and pomegranates The most important crops traded in the El-oubowr market, which need to be preserved by ionic treatment, where the study included the technical study to identify the appropriate doses for each crop through specialized studies in this area, To determine the future demand for the irradiation service during the lifetime of the project. The model of the appropriate irradiation units was then determined, by electronic accelerators. The financial analysis was carried out, including the determination of revenues and costs, as well as evaluating the commercial profitability and pricing system. The marketing capabilities of these agricultural crops to prolong the conservation period and preserve the value and quality of food and to avoid the health and environmental problems resulting from the use of chemicals. The study recommended the establishment of irradiation unit for these crops El-oubowr to prove its technical, marketing, financial and community feasibility.
