Pros And Cons Of Food Irradiation

826 Words4 Pages

While food irradiation is widely approved for human use there are still skeptics that point to the issues when deciding whether or not to use alternatives. Food irradiation is approved by the WHO, FDA, and CDC (Fda.gov) and is used worldwide. However, there are many critics that point to the flaws in the process. The deciding factor for food irradiation is whether or not you see the downsides as outweighing the benefits or vice versa. The main use for food irradiation is to sterilize and extend the shelf life of food. Even though radiation is utilized the food does not become radioactive afterwards unless some of the radioactive material leaks out and reaches the food, which is almost impossible. The issues that surround food irradiation mainly focus on radiation itself and not food irradiation specifically. Food irradiation carries its own risks and rewards and has benefits to it that alternatives do not. …show more content…

It works by breaking chemical bonds with high energy beams to form free ions and free radicals (neinuclearnotes.blogspot.com). Most food irradiation machines use a conveyor belt system that carries the food through the radioactive chamber and back out to the unloading docks. The system is mainly one step, the food just has to stay on the belt and go through the irradiation chamber. The irradiation chamber is powered by a radiation source rack and a storage pool of radioactive material underneath the building. The produce enters the building from a loading dock, enters the irradiated room, and is then loaded back onto trucks to be delivered. There is also another method that uses electrons to sterilize food however, this method is not as popular as the traditional conveyor belt model. When compared to alternatives, food irradiation is safer and a more dependable method of food

There are better and cheaper forms of sterilization available, as well as more widespread knowledge and usage of safety equipment. The roller-tube technique previously mentioned has been since updated to hold more cultures and specialized versions have been made for different types of cells. Binding agents, culture mediums, and even temperature controls have vastly improved (Wray

Most people decide to live in the present or plan for the future in most of their lives, but many people focus on the past not only as their ages of glory but also as the only important point in their lives. A particularly poignant example of this phenomenon is the titular character uncle, Rico, from the movie Napoleon Dynamite. Rico’s saga consists of a middle-aged man who lets his teenage aspirations of being a star football player control his thinking long into adulthood. Uncle Rico provides a fantastic example of the common phenomenon of desiring and dreaming for possibilities from the past instead of actively attempting to improve his own life in the present. Uncle Rico is one of many people in the modern age who live sad existences focusing

These are the questions Public Health and Emergency Management officials will need to ask and investigate. In the short term, radiation exposure of sufficient levels can cause radiation sickness or death. Was there a plume? If there was a pathway, radiation exposure may increase the risk of types of cancer over time. In the article “Radiological Terrorism” it was found that “although radiation is a confirmed carcinogen, it is a weak carcinogen and even radiation levels significantly in excess of natural background levels do not significantly raise cancer risks.

If the environment was exposed to even a relatively small nuclear weapon, studies show that devastating effects would take place against the world’s climate and decade long lasting effects on the ecosystems of the Earth. A small perception that can be used to see the effects of nuclear energy being exposed to the environment is the Chernobyl Disaster of 1986. To this day, there are still no inhabitants of the exposed areas inside Chernobyl, Ukraine, as those exposed can experience heavy vulnerabilities to cancer, diseases, and death. Just from the small accident in Chernobyl, there are still modern effects of the disaster. Things like birth defects, sights of mutated organisms, and sicknesses are still reported as a result from the mass leak of radiation.

The radiation from the bomb is just as deadly as the explosion itself. Radiation is high energy neutrons and gamma rays which come immediately after a detonation of a nuclear device. The beginning stage of radiation, which is short lived, but extremely deadly, where many are killed in a cruel fashion. It is estimated that over twenty percent of all deaths for Nagasaki and Hiroshima were from prompt radiation or the beginning stages of radiation. The second stage is referred to as residual radiation where the high energy neutrons slam into the nucleus of the cell and damage the nucleus, fortunately this is not deadly.

Nuclear expositions produce radiations and the radiations can harm the cells of our body which can lead to a severe sickness or even kill us humans. Radiation is the emission of energy as electromagnetic waves which cause ionization. Radiation sickness is caused by exposure to a high dose of radiation. When these particles come into contact with organic material, they will damage them, causing burns and cancer. Exposure to radiation makes our bodies produce fewer blood clotting agents, called blood platelets, increasing our risk of internal bleeding.

Inventions and procedures based on radiation are still in development today. While some of this technology is 100 percent safe, others can be dangerous and have already caused serious accidents, such as nuclear weapons, which leave devastating casualties. One of the major examples of this are the Hiroshima-Nagasaki bombings in 1945. The bombings may have killed more than 225,000 people altogether. Scientists studying the Hiroshima-Nagasaki bombing survivors found that the occurrence of mental retardation increased among children who received large prenatal doses of radiation (Noto et. al).

There are many different types of radiation, like Microwave Radiation, Alpha Radiation, Beta Radiation, Gamma Rays, and many more. There are also many different ways that radiation affects living organisms. Due to different types of radiation, there will be multiple effects on different organisms depending on the type of radiation. Alpha Radiation is a heavy, very short-range particle and is actually an ejected helium nucleus (2).

Over the years there have been concerns about the effects of workplace radiation on the health and safety of workers. As a result in Australia, as in most developed countries, legislation and regulation has been developed to provide structure and guidelines for the control of radioactive substances, radioactive sources and radiation apparatus. These Acts include procedures to prevent or limit the hazards associated with radiation for the occupational users and the general public. The regulations place requirements on the owners and users of the radioactive sources to be licensed. The licence conditions might include that the radiation sources are secure and that the users have had appropriate and adequate training.

We are always exposed to radiation, but thanks to the shield that the earth provides humans called atmosphere, humans are protected from 99.9% of the dangerous radiations coming from space. When astronauts go to space, instead of receiving the normal dose of radiations that living creatures get on the Earth, 0.00001 Sievert, they get 0.66 Sievert that is the dose that you get if you do a CT scan every five or six days1. This level of radiation may lead to damage to the DNA cells, therefore, causing other diseases2. An example is a study made by the Human Sciences College at the Florida State University which shows that for astronauts who went to the Moon, the proportional mortality rate due to cardiovascular disease is 43%, which is generally

However, radiation exists everywhere on planet. Just forget about planet, radiation is closer to people than they thought. "Most people are totally unaware of the fact that the human body itself is naturally radioactive" (Comby, 2008, para.18) To sum up, I agree with the author on each viewpoints, the pollution due to fossil oils, wide spearing nuclear energy and renewable energy resources is necessary and there is a big bias on people about nuclear, because of unknown things about the nuclear. Nuclear energy is such a new source for mankind.
