Radioactive isotopes are atoms with unstable nuclei that can either occur naturally or by scientists in labs. Radioisotopes have a huge and important effect on the technologies that provide us with food, water and good health. Scientists, doctors and even people everywhere have always struggled with food poisoning and food spoilage because of the insects, fungi or bacteria that can cause human disease or cause food to spoil. Food irradiation is the process in which food is made food safer and more resistant to spoilage allowing it to have a longer shelf life and to be in better condition since it kills disease-causing organisms and slows or eliminates those that cause spoilage leading to it becoming able to stay fresher for a longer period of time. The Radioisotopes that are most commonly used for irradiating foods are cobalt-60 and cesium-137. Food Irradiation has several advantages and some disadvantages which both have their cultural, health and economic effects (Uses of Radioisotopes). 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). Food Irradiation has existed since the 1950s but has been more widely used in recent years. In Asia, specifically China there are 3 large gamma irradiators which in year 2005 got 140,000 tons of food irradiated which is a huge increase from the 80,000 tons irradiated in year 2001. And in India there are two demonstration facilities that use cobalt-60 one processing 30 tons per day and the other 10 tons per day, and even though India mostly uses cobalt-60 there are some beam plants being planned as well. As for in the USA, there are 50 irradiation facilities over... ... middle of paper ... ... • Fruit Being Irradiated. Digital image. Chemistry at Duke. Web. 24 Sept. 2011. . • Irradiated Foods.

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.
...r. Iodine 131, another radioactive element, can dilute very quickly in the air, but if it is deposited on grass eaten by cows, the cows then re-concentrate it in their milk. Absorbed into the body's thyroid gland in a concentrated dose, Iodine 131 can cause cancer. In the Chernobyl disaster, the biggest health effect has been cases of thyroid cancer especially in children living near the nuclear plant. Therefore, because of the Chernobyl disaster we know to test the grass, soil, and milk for radiation. Also, an evacuation of the Chernobyl area was not ordered until over 24 hours after the incident. Japanese authorities evacuated 200,000 people from the area of Fukushima within hours of the initial alert. From the mistakes and magnitude of the disaster at Chernobyl, the world learned how to better deal with the long and short term effect of a Nuclear Fallout.

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..
Without this simple device, many lives would have been lost to fires. Along with smoke detectors, nuclear technology is also used in the wide world of medicine. Chemotherapy is one of the leading ways to combat cancer growth and is helping to extend the lives, and even curing, patients everywhere. While radiation in food production may at first sound like an off-putting idea, radiation is already being used to better grow the world’s farming capabilities by expanding many countries crop outputs. Nuclear technology is everywhere, and that is not a bad
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation means that the rays are able to remove an electron from the atom then ions can be formed. The ions can cause damage when reacting with other atoms. Cells are able to be repaired if low dose are received. However, if cells get a high dose, the cells will be damaged or possibly die. If the cell is damaged permanently then it is referred to as a mutated cell.

Nuclear Medicine is the use of radioisotopes for diagnosis, treatment, and research. Radioactive chemical tracers emit gamma rays which provides diagnostic information about a person's anatomy and the functioning of specific organs. Radioisotopes are also utilizes in treatments of diseases such as cancer. It is estimated that approximately one in two people in Western countries are likely to experience the benefits of nuclear medicine in their lifetime.
A radioisotope is an isotope that emits radiation as it has nuclear instability(Prostate Cancer; Fusion imaging helps target greater doses of radiation).Those who are not too familiar with radioisotopes may think their use is for harmful radiation, nuclear weapons, and the possibility of turning into a giant, raging, green monster. However, there are much more positive uses for radioisotopes. There have been many medical advances thanks to the benefit and practice of radioisotopes in nuclear medicine. These advances have been able to diagnose and treat a variety of diseases.
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.
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
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.
What is radioactivity? Radioactive isotopes are heavy nuclei of certain elements having extra neutrons. The extra neutrons in their nuclei cause them to be unstable so the nuclei break up spontaneously, emitting alpha, beta and gamma radiations. For example,
