Food Irradiation
Food irradiation deals with the process of ionizing radiation with the help of ionizing machines, in order to remove any bacteria, insects, microorganisms, as well as to provide long term solutions for foods, vegetables, and fruits. According to a scientific principle ‘food irradiation’ works through the ionizing machines which are easy to make and there is no need for land or farm to grow foods. Irradiating the foods also change the nutritional value and the taste of the food. The scientific principles involved in food irradiation are as follow: - “Radiation inactivation of microorganisms, disinfestations of stored grains, pulses, dried fruits, and nuts. - Irradiation as a quarantine treatment. - Irradiation of meat and poultry, fish and shellfish, fruits and vegetables, and tuber and bulb crops. - Radiation decontamination of spices, herbs, condiments, and other dried food ingredients. - Process control and dosimetry in food irradiation” (Molins, 2008). First food irradiation is the process of exposing the food to a source of energy that has the ability of removing the electrons from individual atoms in the targeted material (ionizing radiation). Second according to scientific rules the ionizing radiation is emitted by a radioactive substance or generated by high-energy accelerators including X-ray converters. Finally processed foods contain trans-fat, hydrogenated oils and saturated fats, which are worse than animal-derived saturated fats. It is believed that many people are against food irradiation.
It is believed that this topic has become more popular regarding to the ethics involved in “food irradiation” and wonder whether or not the foods that are derived through the process of “irradiation” are safe to...

Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.
Initially the Soviet Government kept the accident at Chernobyl a secret. Because radiation lacks smell or taste, and is invisible, people carried on with their daily lives, all the while inhaling radioactive particles. It took ten days for the Soviet government to evacuate the contaminated areas. Particles fell into the crops and plants of the people. Cows ate grass that had been contaminated by the nuclear particles causing the dairy produ...
I have chosen Food Irradiation as the non-thermal food technology that shows promise for food applications. Non-thermal methods of food processing have become very interesting to those involved in the food processing industry in the last few years. Thermal methods usually dominated the food processing industry; however, these methods can have an effect on the food flavour, texture and nutritional values. However non-thermal methods are becoming more popular as there is minimal impact on the nutritional value or the flavour, texture and odour of the foods. These methods can also extend shelf life as they kill more microorganisms, while being more energy efficient. I will discuss the types of Food Irradiation processes; the techniques used with this method; discuss how this method affects shelf life, nutritional value and sensory value, and compare the benefits and limitations of non-thermal food processes with the benefits and limitations of thermal food processes.
I. Radiation therapy hasn't always been something everyone found to be safe,usable, or effective.It has been cosidered dangerous and sometimes fatal, some also believe radiation therapy will cause the patient to not to get better but to make get worse and very ill. Some people with open minds ponder the question does radiation therapy really cause you to get worse?Radiation therapy can do you good because it kills of cancer cells which could save your life depending on the severity of it. Radiation therapy doesn’t cause harm.

Genetic modification is very harmful for human beings; it has a huge negative effect on animals’ and humans’ health. The manipulation of the genes of crops and animals may cause health damage. “Animal toxicity studies have shown that genetically modified foods may toxically affect several organs and systems” (Arvanitoyannis, 162, 2011). These studies concluded that genetically modified foods are dangerous and they may become one of the most harmful issues in the world. According to Arvanitoyannis research genetically modified foods cause some common toxic effects such as: hepatic, pancreatic, renal or reproductive effects and may alter the hematological, biochemical and immuno...
The purpose of this essay is to explain the positive and negative effects of radioactivity in society today.
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.
According to Dr. Joseph Mercola, 38% of our food is being irradiated. That’s over a third of our food! You may ask yourself, well, what is irradiated food. Well, the process of irradiation is well waves of gamma radiation penetrate our food in an irradiation plant, and the gamma rays kill insects, and bacteria. However, these gamma rays don’t always kill the “bad” bacteria. Food irradiation is a terrible way to clean food, and it shouldn't be happening in this day and age, Food irradiation is very controversial. It has many safety issues, it does negatively affect the food, there’s a lot of government corruption along with a lot of corruption from the meat industry.
Food irradiation is a food safety technology that can eliminate disease-causing germs from foods. Like pasteurization of milk, and pressure-cooking of canned foods, treating food with ionizing radiation can kill bacteria that would otherwise cause food borne disease. The process can also control insects and parasites, reduce spoilage, and inhibit ripening and sprouting. (5) The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively. These studies show that when irradiation is used on foods, as approved, that disease-causing germs are reduced or eliminated. The food does not become radioactive, dangerous substances do not appear in the foods, and the nutrition al value of the food is essentially unchanged. (1)
In the process of food irradiation, food is exposed to the gamma rays or x-ray rays emitted from one of the two radioisotopes cobalt-60 or cesium-137 (The Food Irradiation Process).

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.
One of the greatest events of twentieth century was the use of radioisotope as a source of energy and as medical and industrial tools. Using radioactivity has been a global issue owing to its very nature. When it is used for peaceful purposes, it is a triumph of science because it can solve energy problems in the form of nuclear energy but the side effects in the form of harmful radiation and harmful radioactive waste is the real limitations of science. This essay will attempt to analyze the application of science in the use of radioactivity and radioactive isotopes and how science is not so effective in dealing with the side effects.
