Gamma ray

Gamma rays are the most interesting wave in the electromagnetic spectrum. In 1900, Paul Villard discovered Gamma rays unexpectedly while he was conducting a radioactivity experiment (ARPANSA). He differentiated gamma rays from x-rays because he realized that gamma rays had a greater penetration power depth through his further study and research (ARPANSA). Gamma radiation studies revealed that they are very dangerous, but scientist also found a way to protect against gamma radiation and many beneficial

A single gamma-ray computed tomography (CT) technique, which is a part of unique dual-source gamma-ray computed tomography (DSCT) scanner, was used in this study. This DSCT was originally developed in-house and designed by Varma [49] and the team of Oak Ridge National Laboratory (ORNL) to allow researchers to image and quantify the internal distributions of two- or three-phase flow, which is encountered in different multiphase reactors or flow systems at different operating conditions in a noninvasive

In The Effect of Gamma Rays on Man-in-the-Moon Marigolds, Paul Zindel depicts a world startled by the precarious nature of life. Consequentially, the play focuses intently on the human struggle for acceptance and self worth, and how each individual conforms and reacts to uncertainties. Tillie, the protagonist in the play, struggles to preserve order in her imprisoned life. Her mother Beatrice, discouraged by her own life, controls and restricts Tillie from achieving her full potential. The perplexing

as cancer. Nuclear forces have also provided an alternative energy source to coal and natural gas. The field of nuclear chemistry encompasses many aspects including nuclear decay, radioactive elements in medicine, and nuclear energy. Alpha, beta, gamma - to many people those three words are the first three letters of the Greek alphabet, though

Natural radiation is the radiation provided from natural occurring substances such as the sun's UV rays and the earth's crust. Natural radiation includes elements such as Uranium and Radium. Artificial radiation is synthesised (man-made) in ways such as bombarding a stable nucleus of an element with energy to create radioisotopes. This man-made radiation includes substances such as nuclear power. Electromagnetic radiation which includes waves such as radio waves, microwaves and visible light. Theses

warn against drawing conclusions about the impacts on sea life before peer-reviewed studies are completed. Secondly, gamma rays can be used in medical treatment to kill cancer cell. However gamma can be extremely dangerous because they are a very powerful source of power, if they delivered in an unmonitored and uncontrolled way they can kill humans, animals and plants. Gamma rays however can also disrupt the physical properties of materials. They can cause plastics and steel to become brittle and

to radiation, such as using gamma rays for sterilization. There have been many controversies about food irradiation. Some people say that using nuclear technology on food can cause harm to the body. But I believe that using nuclear technology is the best way to remove any diseases on food to cause less harm to the human body. Irradiation can also be used to preserve nutrients in food and kill microbes that destroy them. Using preservation procedures exposes food to gamma radiation, a high-energy light

radiation is captured by external detectors (gamma cameras) to form two-dimensional images. What is Technetium-99m? Technetium-99m is a widely used radioactive tracer isotope in Nuclear Medicine. Its gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process. A further advantage is that the gamma is a single energy, not accompanied by beta emission

Introduction It is difficult to determine the birth of nuclear medicine due to the many contributions made my scientists of carious fields. However, most notably, during bla blah Understanding the uses, benefits and side effect of nuclear medicine is crucial due to its significant and ongoing contribution to the medical field. Throughout this paper focus will be placed on how radioactivity has benefited the detection, control and at times, complete elimination of cancer. Background Nuclear medicine

Sterilising- Gamma rays which are high energy electromagnetic waves that can only be stopped by thick lead, this means they can pass through medical equipment because they aren’t made of lead, such as syringes. When gamma rays pass through packaging they inactivate viruses and kill bacteria. If the equipment stays in a sealed plastic bag it will remain sterile. Treatment- Radiation treatment is the most common therapy/treatment for cancer. Its users high energy particles such as X-rays to destroy
