Gamma ray Essays

Gamma ray bursts (GRBs) are the most energetic event known in the universe. An interesting thing about these events is that they currently pose a potential threat to mankind’s existence. Here we will talk about what exactly GRBs are and how they’re caused, as well as what kind of potential dangers they present to the earth and life as we know it. Gamma ray bursts are two brilliant ejections of light, and gamma radiation. They are caused by the deaths of large stars. When a star is big enough, it

X-rays passes through the human body and create images of structures such as bones, symptoms of diseases and injuries and some organs. Radioactive decay (radioactivity) is the course of when a nucleus loses energy from an unstable atom by emitting ionizing radiation. A radioactive material can be emitted of alpha, beta, gamma particles. Gamma radiation or ‘gamma rays’ are electromagnetic radiation of an extremely high frequency and high energy photons but because of this, gamma rays are ionizing

Semester 2 BCD Radiation and half life. Nora Bessenyei 9c How does year's affects the radiation of an element ? Through this experiment I will be looking different factors that can affect half-life. To have a better understanding of the experiment some basic terms needs to be defined. Such as radiation, Different type of radiation, isotopes and half-life. Isotopes can be divided into 2 groups. Stable and unstable isotopes. Isotopes that has an atomic number lower than 83 it is stable. If the

Cobalt-60 is a radioisotope that emits a form of electromagnetic radiation from the isotope cobalt-59, through gamma decay. This radioisotope can be used all throughout the body and is an essential factor for cancer therapy and critical complications to the brain like brain tumors. The reason for this is because cobalt-60 is very precise and one of the most advanced radiation treatment obtainable in our society. Cobalt-60 is not only used for medical or surgical purposes but is needed for the industry

should not be used on the human body. However, it is a significant part in the development of medicine. Problems inside the body are going undetected because most of the time they do not have any severe symptoms until it is too late to treat, and x-rays and scanners that use radiation to look through the body are dangerous because they may emit too much radiation on the patient, causing issues in the future. This is where nuclear medicine comes in as a better solution. Over 10,00 of hospitals worldwide

allergic reaction. Therefore, the patient must tell the technologist, doctor or nurse before the radiopharmaceutical is given to him/her. However, cases of allergic reactions are very rare (Cain, 2013). The second safety risk issue is radiation. Gamma rays of this system are ionizing radiation that causes changes in body’s molecules. Too much exposure to ionizing radiation can damage the tissues. Children, young women and fetus are more sensitive to this type of radiation than others (Fahey, 2012)

and treatment of cancer. Isotopes are versions of an element that have an equal number of protons, but an unequal number of neutrons; thus making the atoms radioactive and able to emit alpha, beta, and gamma rays. In the diagnosis of types of cancer, the injection of isotopes can radiate these rays, which can be detected by special equipment to track their location and how they move. Isotopes are not only good for detecting diseased cells, but destroying them as well. The energy that is given off

body’s level of enzyme, vitamin absorption, sites of seizures (epilepsy), access damages and analyze whether the body is responding to treatments or changes within the body. Unlike other diagnostic devices (e.g., computed tomography (CT) scanners, x-rays, magnetic resonance imaging

Nuclear Medicine: Do the Negatives Outweigh the Positives? Nuclear medicine has been around for a long period of time and improvements are constantly being made to its procedures but one question still remains prominent: do the negatives outweigh the positives? Before beginning to evaluate this question by looking at the particular risks and benefits in procedure and production, it’s necessary to understand the basics of nuclear medicine. Nuclear medicine is the branch of medicine that deals with

Gamma ray bursts are short, but massive explosions of high frequency electromagnetic radiation. The initial bursts are usually followed by a longer afterglow emitted at a longer wavelength. These bursts (in minutes) give out more energy than the sun during its entire lifetime (10 billion years) and are the most powerful explosions known in the entire universe. They can last from 10 milliseconds to several hours. Gamma-ray bursts are divided into two groups, long and short, depending on if they last

However, what is it really? Radiation can be classified in to two types. There is nonionizing radiation and ionizing radiation. Nonionizing radiation doesn’t harm humans right away and is what we think of when radiation is mentioned such as ultraviolet rays and microwaves. Though

Nuclear Medicine is an incredible scientific advancement that can be used to cure many diseases such as cancer and to look at our bones. In this essay I will be focusing on cancer and diagnosis of diseases. I think this advancement is so important because it can provide doctors with the ability to accurately diagnose people and figure out how to help them. While this is important, there are some social issues. Though there are risks, the positives trump the negatives when it comes to nuclear medicine

Radiation, a word used all too loosely. But what really is radiation? How does radiation really effect your body? Radiation is the process of giving off energy in the form of waves or particles and, can have numerous long and short time effects on the human body. Radiation takes place when the atomic nucleus of an unstable atom decays and starts releasing ionizing particles. This process is known as ionizing radiation. If exposed to radiation, there are many effects that can happen to you and your

Position Overview Nuclear medicine technologists are specialized health care professionals who operate imaging equipment that examines how an area of a patient’s body is functioning in order to help in the diagnosis or treatment of varying diseases and conditions. Nuclear medicine technologists are also responsible for preparing and administering radioactive drugs called radiopharmaceuticals that uses radiation to highlight abnormal areas of a patient’s body so that it is easy for the technologist

The Discovery of Radioactive Elements Radiation is now known as very dangerous and unhealthy, imagine a time when mentioning radiation everyone thought of the healing properties and considered it a cure all. To understand why it was considered a cure all, in the 1900’s we must go to the very beginning when Uranium was discovered. The beginning of Radioactivity Uranium was discovered in an old silver mine called Joachimsthal located in the city of Jáchymov in the Czech Republic.The mine

Thanks to nuclear medicine, treating diseases has become safe, eliminating past procedures such as surgery. Nuclear Medicine is powerful enough to cure diseases. I believe they are used ethically because of the pro use of this technology to save a person's life. Even though there are disadvantages of using this, such as the mild radiation that it has, the advantages outweighs these cons because of the accuracy this technology lets us see in the most sensitive parts of our body. (Frederic Fahey) This

diagnostic and therapeutic services. It contributed towards the expansion and upgrade of current nuclear medicine status and services in the health sector. Impact of nuclear medicine equipment Essentially, nuclear medicine relies heavily on computers and gamma cameras dedicated to cardiac work in view of the fact that they are recognized through their highest industry in performance. The technicians have influenced the

joints, etc. Nuclear medicine can be swallowed, inhaled, or injected into the human body, just depending on the type of radiotracer given. The tracer then collects in the area that is targeted for the treatment given. During the process of scanning, a gamma camera is used to locate the signals emitted from the tracers in the organ for

Effect of Gamma Rays on Man-in-the-Moon Marigolds by Paul Zindel, the significant symbols is the marigolds and the gamma rays. The marigolds represent Tillie, the main character, and how her mother affects her life. Her mother, Beatrice, also is important since the gamma rays in the play represent her. These symbols help reveal the characters personalities and the theme in the work. The symbols appear and function in this play because Tillie does her science project on marigolds and gamma rays. Tillie

infected or the diseased areas of the body. The device known as GAMMA CAMERA produces an image to locate the Radionuclide particle. It is a technique of imaging the parts of body like various organs, bones, brain, etc. by using small doses of radioactive chemical particles which depends on the part of body is introduced for scanning. A Radionuclide is also known as a radioisotope which is a chemical and emits radioactivity known as gamma rays. A very little amount of radionuclide is inserted into the
