    2.3 β-particle emission radionuclides Β-particles are high energy electrons which are ejected from the nucleus with a range of energies up to a maximal value.12 β-emitters are heavily researched and are a widely accessible form of radionuclide therapy. The LET of β-emitting particles is high enough to kill cancerous cells, but is considered low compared to α-emitters which have a lot more particles in the higher energy levels. Β-particle emitters deposit their energy over a much larger range (1mm

    element to another through particle and gamma decay. Essentially, all radioactive materials are byproducts of previously decayed elements. In order to utilize the radioisotopes of their choice, providers must artificially employ forms of specific radionuclide formation. This process is induced in a variety of ways, namely, production in a particle accelerator or creation in a nuclear reactor. “Overall there are some 3800 radioisotopes. At present there are up to 200 radioisotopes used on a regular basis

    1506 Words  | 7 Pages

    Introduction Isotopes are elements which have the same number of protons but different number of neutrons and these elements have same atomic number but different in atomic mass.because of their characteristic nature of producing radiation and their energies. Isotopes are used in various areas like industries, agriculture, medical field and research centers. They are decayed by emission of energy in the form of alpha, beta (electron) beta plus (positron) and gamma rays. (1) Types of radiation Alpha

    in a vast array of nuclear medicine procedures, including diagnostic and therapeutic procedures. The four forms of terbium under clinical trials are 149Tb, 152Tb, 155Tb, and 161Tb. 149Tb is being clinically tested as an alpha particle emitting radionuclide for alpha-immunotherapy. Due to it’s relatively short half-life of 4.1 hours and low energy emittance of alpha particles, make it principally well suited for application in unification with small-molecular-weight targeting agents, including peptides

    Radiation Cleanup Organizations The Environmental Protection Agency (EPA) estimates that there are over one thousand sites in the United States contaminated with radionuclides. Many of these contaminated sites have been thoroughly cleaned in a process to decontaminate the site to meet certain standards. These locations vary in size ranging from a small laboratory to a decommissioned nuclear power plant and even a large scale nuclear weapons facility. The Department of Energy (DOE) along with many

    Tatsuya Tsunemi Radioactive Isotopes What is a radioisotope? An isotope means that same chemical elements but they are able to gain and lose some neutrons and it means they have different mass numbers but that are all still the same element because they all have same atomic number and same amount of electrons. Some of them are stable and unstable and unstable ones start radioactive decay by time because of some reasons which includes they cannot keep staying together, they have too many or too

    Nuclear Medicine is the use of radioisotopes for diagnosis, treatment, and research. Radioactive chemical tracers emit gamma rays which provides diagnostic information about a person's anatomy and the functioning of specific organs. Radioisotopes are also utilizes in treatments of diseases such as cancer. It is estimated that approximately one in two people in Western countries are likely to experience the benefits of nuclear medicine in their lifetime. To understand what a radioactive isotope

  • Nuclear Medicine And Its Effects

    1150 Words  | 5 Pages

    Nuclear medicine refers to the use of radioactivity to diagnose and treat diseases. Nuclear medicine is a rapidly expanding branch of chemistry that uses short-lived radioisotopes to seek out specific organs. Nuclear medicine can detect radiation coming from inside a patient’s body and as a result nuclear medicine can determine the cause of the medical problems based on organ’s function. The use of nuclear medicine techniques have increased due to its’ use of biological chemistry to target specific

    Running head: NUCLEAR MEDICINE 1 Concepts of Nuclear Medicine NUCLEAR MEDICINE 2 Concepts of Nuclear Medicine * What type of radiation is typically exploited in most nuclear medicine procedures? Nuclear Medicine is a specialty used to diagnose and treat diseases in a painless and safe manner, which uses a pharmaceutical (medicine) that’s attached to a small amount of radioactive material (a radioisotope). The procedures can often identify disease in an early stage

  • Gastric Emptying Studies

    270 Words  | 2 Pages

    What is a gastric emptying study? The definition of a gastric emptying study is “a procedure that is done by nuclear medicine physicians using radioactive chemicals that measures the speed with which food empties from the stomach and enters the small intestine”. What does it have to do with nuclear medicine and radioactive elements? That’s a good question. It has to do with radioactive elements because the meal, liquid, or both are mixed with a little bit of radioactive material, than gamma rays
