of all what is a Gamma Ray? A gamma ray is a high energy ionized radiation (EPA). Gamma photons have about 10,000 times more energy as photons (EPA). Along with that gamma rays wavelengths are so short they have to be measured in nanometers (EPA). They also are the strongest type of radiation which makes them the most dangerous. How are Gamma rays dangerous? A gamma-ray photon has enough energy to damage atoms in your body and make them radioactive (Christian, Eric). Gamma ray radiation also causes
This paper talks about the gamma-ray explosions that occur in the universe and its effect if it were to occur close to the earth’s surface. The most energetic explosions to be recorded in the universe are the gamma ray bursts. Gamma ray bursts forms a representation of the events that occur in the cosmos due to its large luminosity that has been detected to approximately z-8.3. This has offered an exciting experience in the study and research of the astrophysics in its extreme condition. The paper
Since the day I was born, scary movies, rollercoasters, and haunted houses were not my "thing". I never appreciated scary pranks, darkness, and bloody movie scenes. I never knew, however, that I would get the scare of my life seven years ago. My heart never pounded so hard and I never felt such a trembling sensation throughout my body. August 14, 2003 was one of the worst days of my life, period. That Thursday will never be forgotten. Early in the morning, too early to remember, Mom walked into
Pros and cons of gamma ray imaging Gamma imaging can obtain reliable porosity and saturation information in quite wide range of model size from couple centimeters to several meters. However designing a well calibrated system is a challenge and may take several days to achieve. Another concern is the acquisition time that can take up to one minute for capturing a single location with the plane size of 1 cm2. Therefore in bench scale scanning time will exceed hours and therefore studying steady state

In the nuclear industry there are many benefits and risks. Nuclear energy, medicine, and the food industry show this. I feel that benefits outweigh the inherent risks. I think this because there in nuclear energy there are benefits, like how it is the world’s largest source of emission-free energy. In medicine there are many radioisotopes used to benefit humans through treatment. Radioisotopes are used to diagnosis and treat many forms of cancer and other diseases. In the food industry irradiation
How does an X-ray work? X-rays are electromagnetic waves that are like light. They can penetrate materials with masses to different levels. When the x-rays hit the film, it creates an image which shows it like a light would. Since bone, fat, muscle, tumors and other structures all absorb x-rays at different levels, the image on the film lets you see different distinct structures inside the body. This is because of the various levels of exposure on the film. What is radioactivity? What is radiation
has both beneficial and harmful effects. The most detrimental health effect on humans, is the incidence of cancer, which has been studied. Humans are exposed to radiation more than they realize. They are exposed medically with x-rays, just by being outside with cosmic rays, and by accidents such as at the Chernobyl Nuclear Power Plant. Exposure to radiation is high and more studies are done which improve radiation protection. The Chernobyl disaster is one such example in which the studies done

distinctive ideas created discoveries and theories that made him famous, up to a point that he's even being considered the father of nuclear physics, not an everyday title. Nowadays we know of certain types of rays thanks to Edward, even though he basically named them. A sturdy example would be the gamma rays, that are used in therapeutic machines. Ernest basically implanted a seed in science which later developed into massive discoveries. Biography Ernest Rutherford was once born in Nelson, New Zealand.
During the 1800’s, the late 1800’s, scientist discovered radioactivity. The study of radio activity became a phenomenon amongst scientist during this time period. With the discovery of new elements polonium and radium by Marie and Pierre Curie, the use of radioactivity to probe the center of an atom, provided the instructions of a nuclear weapon that will kill innocent Japanese, leaving there face disfigured, and permanently changed. The majority of people know of the effect of radioactivity but
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
According to Helibron and Seidel (2011) nuclear medicine began as a simple experiment in the early twentieth century by George de Hevesy. De Hevesy started the experiment by deciding to test the effects of radiation on living things, beginning with bean plants, then onto furred animals, and then continued onto finding the effects of radiation on the human body, when he did this he became the first person to ever use radiation on a human being. He along with his partner E. Hofer, in 1931, consumed
There are many uses for radioactive substances. In the medical world, there are a number of health care processes that make use of the properties of the nucleus. This is also known as Nuclear medicine ("Nuclear Medicine"). In this essay, we will be looking at a particular nuclear medical treatment; we will be looking at radiotherapy. Radiation therapy usually refers to the ionizing radiation. Ionizing radiation is mostly used in oncology, but it can be used for other purposes such as ionizing an
doses of radiation everyday. The type of radiation that is very lethal to humans and all other life is gamma radiation. This type of radiation, if you are exposed to it, alters the molecular structure of your DNA and can lead to mutations in your offspring and can lead to diseases like cancer. Alpha and Beta particles are usually deflected by your skin and they aren’t as harmful. Alpha, Beta and Gamma radiation are types of ionizing radiation which means they can remove the electrons in the atoms of
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
Genetically Modified Crops Genetically modified crops (GM crops) climb to the top on the hotly debated issues list of society. In 1996, no GM crops were cultivated on a commercial scale in the United States. In 2002, 75% of soya, 71% of cotton, and 34% of all maize grown in America is GM ("Grim Reaper" 1). Many issues surround this controversial topic such as safety, ethics, and foreign relations. Many of these concerns are well stressed in mass media, but sometimes biased views are the
radiation inside a nuclear reactor during fission (Nuclear Energy 2005). Fission occurs when an atom’s nucleus splits into two or more smaller nuclei, producing a large amount of energy. Radioactive isotopes release radiation in the form of beta and gamma rays. The strength of the radiation is relative to the rate where radioactive material decays. Because of this, different radioisotopes can be used for different purposes, depending on their strength. (Nuclear Energy 2005). Radioactive isotopes
Radiation and its Effects on the World The biological effects of radiation play a key role in today’s society and it is something that all species have to deal with on a day-to-day basis. Throughout time, this field of study has grown and has become one of the most prominent fields of science. Radiation is something that we as a human race will never be able to escape. It is naturally present and has been since planet Earth was formed. In the mid 19th Century, there were two famous scientists that
