Gamma distribution Essays

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

Radioactivity or radiation therapy uses high energy rays or radioactive substances to damage tumor cells or halt their growth, it has been used alone or along with other treatments as an effective tool for treating cancers for over one hundred years, It is estimated that about two-thirds of all cancer patients will receive radiation therapy as a stand alone treatment or as part of a more comprehensive treatment protocol. Before Ionizing particle beams, few options for both benign or malignant diseases

Radiation with adequately high vitality can ionize molecules; that is to say it can thump electrons off iotas and make particles. Ionization happens when an electron is stripped (or "thumped out") from an electron shell of the iota, which leaves the particle with a net positive charge. Since living cells and, all the more critically, the DNA in those phones can be harmed by this ionization, introduction to ionizing radiation is considered to expand the danger of growth. Subsequently "ionizing radiation"

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

Radiation is something we are all aware of in a general term. However, many of us do not realize the science or depth within the field of radiation. Radiation is not something we can see to defend against. It is not something many of us are aware of just how dangerous it can be. The Last Ship goes into the science of radiation and what effect it has on the human race. It brings into light the power that radiation holds on us. Everyone knows of the term, radiation. However, what is it really? Radiation

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

Marketing strategy Customers Youth, families, tourists, older customers and the middle working class Product life cycle. According to Kotler, P. & Gary, A. (2011), the product life cycle has five stages namely product development, introduction, growth, maturity and decline stage. The stages are determined by the market share of the product. Before the product enters the market, there are no sales, as the product is being prepared for the market. There is market research that is being conducted. Introduction

Although there is a significant growth scope in the market, however the technology changes, e-business, social media have lowered the barriers for the new entrants and increased the competition based on quality, price, convenience and brand identity. The existing firms have the additional advantage in terms of brand identity, capital expenditure and economics of scale over the new entrants. Additionally the aggressive campaigning and the brand extension by the existing competitors may create barriers

Radiographers should always apply the As Low As Reasonably Achievable or ALARA principle when undertaking a medical X-ray exposure. There are evidences that demonstrate that diagnostic X-ray procedures have the ability to induce cancer and genetic effects, although the risk is known to be very low. Hence, it is the responsibility of radiographers to always ensure to minimise this risk by minimising the radiation dose to the patient, ultimately producing the best diagnostic image and delivering the

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

Radiology would not be complete without mentioning rays. It's our ability to harness these Ray's and translate them into images that makes the field of radiology viable. X Ray machines in particular are used in identifying, diagnosing and treating a vast array of diseases. The mechanism for X-rays differ, but they all have the same principle. The person credited for discovering X-rays is the German physicist Wilhelm Roentgen who discovered it by accident. While messing around with an electron beams

Background When Ionizing radiation comes in contact with living things on an atomic level, it can have several different effects. Sometimes it causes no damage to the cell, and if it does, cells have the ability to repair themselves. However, in other cases, the radiation can damage the DNA and affect the cells ability to reproduce correctly, and thereby cause mutations. In extreme cases, radiation call also kill the cell. (scholes) It has been found that exposure to radiation can cause a considerable

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

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

(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 radiation to the human body which can be dangerous. Positron Emission Tomography (PET) is a nuclear medical imagining device that collects inimitable

oncology field and can be used for the detection 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

why nuclear medicine uses specific radioisotopes to scope the body and detect complications inside the body; all of the radioisotopes used have very short periods of radioactivity. 99mTc has a half life of 6 hours, meaning that after it emits the gamma rays or internal conversion electrons (a radioactive decaying process where a stimulated nucleus interacts electromagnetically with one of the orbital electrons), the isotope will return to their ground state and won’t emit radiation anymore. The
