  • The Pros And Cons Of Ionizing Radiation

    946 Words  | 4 Pages

    Distinction must be drawn at this point between ionizing and nonionizing radiation especially with regard to their interaction with biological systems. Ionizing radiation has the ability to damage components of cells. Nonionizing radiation, on the other hand, such as radio waves and microwaves do not have similar capabilities and can at best cause heating of tissues. This claim though has been seriously doubted after a thorough scientific scrutiny, as we shall see later. Electric fields are easily

    Radiation can be defined as the energy travelling through space which comes from a source and may be able to penetrate various materials. There are two types of radiation and they are the non-ionizing and ionizing radiation. Non-ionizing radiation consists of light, radio and microwaves. Whereby ionizing radiation can produce charged particles in matter, and ionizing radiation is produced by unstable atoms. The difference between unstable atoms and stable atoms is that unstable atoms have an excess

    be understood and can be visually determined. With that being said one major difference in the way that the two techniques obtain their images is the use of radiation. In an X-ray scan the use of gamma radiation helps with being able to obtain an image of an internal structure of the body. Whilst an MRI scan will use magnetic radiation to achieve the same goal. Therefore X-rays scan are more favourable when it comes to determining bone injuries and MRI scan are favourable

  • Chemistry: A Case Study Of Hydrogen Electron

    752 Words  | 4 Pages

    1 The hydrogen atom has one electron which can occur in 3s, 3p and 3d and since it is one electron it experiences the same nuclear charge (full nuclear charge). The effective nuclear charge felt by more than one electron in an orbital is not the same. This is due to electrons have the same charges, thus repel each other and shield the nucleus. Helium has two electrons; hence electrons repel each other and shield the nucleus. Additionally, the 1s orbital is close to the nucleus as compared to 3s

    It is an isotope of the artificially-produced element technetium and it has ideal characteristics for a nuclear medicine scan. It has a half-life of six hours which is long enough to examine metabolic processes but short enough to minimize the radiation dose. It decays by isomericly which emits gamma rays and low energy electrons. The low energy gamma rays it emits easily escape the human body and are accurately detected by a gamma camera. The chemistry of technetium is so versatile it can form

  • Pyrene Case Study

    979 Words  | 4 Pages

    Pyrene is a good luminescent probe as it can undergo fluorescence that has a long lifetime, 1/2  100 ns, and its fluorescence is highly dependent on the polarity of the solution it is in. Pyrene’s emission spectrum can provide information about the microenvironment it is in. The molecule is a rather large elongated pi-conjugated system, making it nucleophilic and impossible for it to have any affinity to a charged surface such as silica.

    advances, doctors can identify diseases before they become a problem and treat them effectively. “Disease is a biological process, and nuclear medicine provides images of these processes.” Most radiotracers interact with a biological process and emit radiation. Detector systems collect these signals, and computer programs rebuild them into diagnostic images. Nuclear medicine differs from other imaging techniques which visualize structure and shape (anatomy) versus a biological process (physiology)(U.S

    radiology is to obtain images which are adequate for the clinical purpose with minimum radiation dose to the patient. If optimum performance is to be achieved, assessment of image quality must be made to balance against patient dose. X-rays are known to cause malignancies, skin damage and other side effects and therefore are potentially dangerous. It is therefore essential and mandatory to reduce the radiation dose to patients in diagnostic radiology to the barest minimum (Watkinson, Moore’s., 1984)
