Introduction
There have been an increasing number of foodborne illnesses in this country and throughout the world in recent years. This has led to a heightened awareness of food safety. Food irradiation is being looked at as a potential solution to the problem. Food irradiation is the process of exposing food to ionizing radiation. Research shows that food irradiation can reduce or eliminate harmful pathogens and bacteria in our food, thus reducing, or even stopping the spread of foodborne illnesses. Proponents argue it has many benefits and will increase public safety. They believe it will increase the shelf life of the products we buy, and decrease the need for the use of other harmful chemicals. Ultimately, they believe food irradiation is a viable option to increase the safety of our food supply.
Everyone does not share those feelings. Opponents of food irradiation are concerned about the safety of the process, and the long-term effects. They believe it opens up a new can of worms, with it’s own set of problems. These include the effects the irradiation has on the make-up and nutritional value of the food. They argue there are many environmental concerns to be considered. Opponents of food irradiation do have concerns about the outbreak of foodborne illnesses and the safety of the food supply. However, they feel it is an unnecessary extreme. They believe we should carefully evaluate our food handling practices. They believe a clean up of current conditions would greatly improve food safety. With the proper implementation of standards, we would not need to go the extreme of food irradiation.

Companies nowadays are using different and strong methods in marketing their food products. The Companies are very competitive, and the results can affect the people. When we think about this job field, it is convincing that those producers should use cleverly ways to gain their own living. In the other side they shouldn’t use misleading ways that could harm the people. Food companies should be straightforward with every marketing method they use. People have the right to know what they are consuming and also to know the effects of these products on them, whether it is harmful, useful, or even neutral.

One of the biggest and longest lasting environmental impacts of the detonation of the atomic bomb is the radiation contaminations that are left over. These contaminations spread into water, air, animals, soil and into the atmosphere. What’s worse is that these contaminations have materials that have very long half-life meaning that their radiation effects do not decay quickly. “Many of the substances released, including plutonium, uranium, strontium, cesium, benzene, polychlorinated biphenyls (PCBs), mercury and cyanide, are carcinogenic and/or mutagenic and remain hazardous for thousands, some for hundreds of thousands, of year” (The Effects of nuclear weapons). The spread of these contaminates will cause significant health risks to animals ca...

This is the major contributor to worldwide radiation exposure, Non-medical, man-made radiation used in small amounts in food irradiation, airport security scanners, and some consumer products. Exposure to man-made radiation can happen in certain workplaces, or in communities as a result of above ground nuclear weapons testing and nuclear accidents
Radiation has many benefits for humans, but too much of any type of radiation can be harmful. For example, the sun gives off infrared radiation, or heat, as well as visible light, another type of electromagnetic radiation. These ...
Information on the effects of comes from studies of exposed, from animal experiments, and from studies at the cellular level. It is now well recognized that radiation has both timely and postponed effects. At very high radiation exposures, death will occur within several months or less. At moderate levels, radiation exposure increases the chance that a being will develop cancer, with a time delay of ten or more years. At low levels, the cancer risk decreases, but the bond between cancer risk and the scale of the exposure is hesitant.
Irradiation is a ‘magic bullet’ that will enable [the company] to say that the product was ‘clean’ when it left the packing plant (OCA, 2001). The claim, more rather, lacks the key source in evidence, for even the best sanitation and standard antibacterial treatments cannot ensure safety in foods. In addition, irradiation cannot occur properly if the food is too heavily contaminated, preventing industries from using this practice as a substitution for good sanitation practices. Irradiation is not harmful in producing resistant strains of bacteria, nor does it make food radioactive. It simply reduces the amounts of bacteria in foods that may become potential illnesses in humans. Accordingly, food irradiation advocates 40 years of research showing the process to be safe, however, evidence for this assertion is missing. An article in the Nation’s Restaurant News states that detractors of irradiation paint the process as a potential health risk that has not been studied sufficiently (Liddle, 2001, p 60, 3p, 4c).
Although the US food supply has achieved a high level of safety, microbiological hazards exist. Because foods may contain pathogens, mishandling, including improper cooking, can result in food-born illness. Irradiation has been identified as one solution that enhances food safety through the reduction of potential pathogens and has been recommended as part of a comprehensive program to enhance food safety.
Radiation is a frightening concept. It has lead to many an untimely death in the past 70 years, ranging from victims of atomic bombs in Japan to physiologists experimenting without taking proper safety precautions. The most dangerous form of radiation can be devastating to the body, weakening or eliminating the immune system and tearing the very DNA in one’s cells apart. This form is referred to as ionizing radiation, and even the least harmful potencies - such as x-rays and UV light - can increase the risk of cancer and other health problems. It has enough energy to knock electrons out of atoms in a process called ionization.

Food safety is an increasingly important public health issue. Governments all over the world are intensifying their efforts to improve food safety. Food borne illnesses are diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. “In industrialized countries, the percentage of people suffering from food borne diseases each year has been reported to be up to 30%. In the United States of America, for example, around 76 million cases of food borne diseases, resulting in 325,000 hospitalizations and 5,000 deaths, are estimated to occur each year.” (Geneva 2)
On the other hand studies have reported that fermentation increased the crude protein content of pearl millet flour (Fasasi 2009). Natural fermentation at 20, 25 and 30°C for 72 h brought about a significant reduction in phytic acid content and increased polyphenol content of pearl millet flour and an improvement in invitro protein digestibility (Neelam et al 1991). Ionizing radiation in combination with cooking reduced IVPD (Siddharaju et al 2002: Ravindran et al 1995). Higher protein digestibility after radiation treatment may be due to increased accessibility of the protein to enzymatic attack However; this effect could also be due to inactivation of proteinaceous antinutritional factors (Van der Poel 1990). Thus, protein digestibility may be decreased and/or increased without incurring amino acid destruction (El-Hakeim et al 1991). Therefore, it could be concluded that the radiation process offers a good treatment for
The impact of nuclear power on the modern world has improved Various sectors of the economy and society .i.e. Food and Agriculture, Insect control, Food Preservation, Water Resources, Military, Medicine, Research and Industry. “In 1911 George de Hevesy conducted the first application of a radioisotope. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed.
As atomic power is increasingly recognized as a potential energy source to sustain future human development, radiological protection of the environment will become an even more important environmental safety concern (ICRP 2003). In the past decades, scientific and regulatory activities related to radiation protection has been focused on the radiation exposure on humans. The prevailing view has been shown that, if humans were adequately protecte...
