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)
Raw meat and poultry treated with irradiation could eliminate bacteria common for these foods, such as E. coli, Salmonella, and Campylobacter. Irradiating prepared, ready- to eat meats such as hot dogs and deli meats, may eliminate the risk of Listeria. Additionally, Cyclosporine parasites and bacteria such as Shigella and Salmonella from fresh produce could be removed. There is also potential benefit for dry foods that are stored for long times and transported over great distances, like spices and grains. (1)
Bulk or packaged food passes through a radiation chamber on a conveyor belt. The food does not come into contact with radioactive materials, but instead passes through a radiation beam, like a large flashlight. The type of food and the specific purpose of the irradiation determine the amount of radiation or dose, necessary to process a particular product.
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...

There are numerous reasons as to why I want to pursue my dream of becoming a radiation therapist. The most important reason is because I love to help other people overcome any problem they are facing. However saving a patient’s life through radiation would be even more amazing. Not to mention, after obtaining the proper education, the salary I receive will be fairly high. Cancer has recently become a part of many families, including my own. I see what a few of my family members are going through and having to struggle with every single day in order to live to see another day, The struggles that they go through have opened my mind in many ways, I wish I was the one that they could come to for a chance of survival, but I can’t, so in order for me to help cancer patients fight for their lives, I will obtain the proper education, licenses, and possess the numerous skills needed by a radiation therapist..
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...

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)
Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field. Normal people out the world can also be exposed when coming into one of these offices and getting x-rays of some type.
Handling, processing, and preparation such as (cooking, cooling, reheating, holding/service) should be controlled to ensure that the food is not contaminated in any way.
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.
Each and every year millions of people become sick because of food poisoning and other food related illnesses. Many of these illnesses can easily be prevented by properly cooking and handling food in the kitchen. Unfortunately, many people around the world are unaware of the consequences that can occur from contaminated and undercooked food. It is important for every individual who is planning on making a meal in their life (virtually everyone) to understand how to properly prepare their meal.
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.
Canning is a simple method for capturing food’s delicious and wholesome qualities at natures very best and for preserving food for enjoyment at a later time. Nowadays people choose for can because it may saving the available food for later use. One of the most common methods for preserving foods today is to enclose them in a sterile container. Canning can be glass, plastic and metal can and the basic principle of canning is that a food is sterilized, usually by heating, and then placed within an air-tight container. In the absence of air, no new pathogens can gain access to the sterilized food. In most canning operations, the food to be packaged is first prepared in some way—cleaned, peeled, sliced, chopped, or treated in some other way—and then placed directly into the container. The container is then placed in hot water or some other environment where its temperature is raised above the boiling point of water for some period of time. This heating process achieves two goals at once. First, it kills the vast majority of pathogens that may be present in the container. Second, it forces out most of the air above the food in the container.
Food is a product that is rich with nutrient and can be contaminated with exposed to major source such as water, air, dust, sewage, insects and rodent (Oi Nee and Norrakiah, 2011). As a food handler they need to handle the changes in preparation techniques and food production because the fact remains whereby food is the source for microorganism which can cause illness (Oi Nee and Norrakiah, 2011).
