PRELIM Flashcards
Branch of medicine and medical imaging that uses a small amount of what we call radio tracers, or radiopharmaceuticals, to diagnose disease and to treat disease, including many types of cancers, heart diseases and certain other abnormalities within the body.
NUCLEAR MEDICINE
Nuclear medicine looks at ________ of the body and of all the organ systems. We can follow the physiological processes as they occur in a living human using these radiopharmaceutical and through use of appropriate imaging system.
physiology
Martin Klaproth discovers Uranium and named it after the planet Uranius
1979
Henri Becquerel uses Uranium and radium to discover alpha and beta rays, type of radiation
1896
who discovered gamma rays
Paul Villard
Pierre and Marie Curie first used the word “radiation” to describe the rays they were finding; they also discovered Polonium and radium.
1989
used radiation to kill bacteria in food & what year
Samuel Prescott, 1989
Ernest Rutherford and Frederick Soddy establishes the theory of Nuclear Reactions (by bombarding alpha and beta particles)
1902- 1919
Father of Nuclear Medicine, conceives the idea of radioactive tracers
1911 – George von Hevesy
a Boston physician, first used radioactive tracers to diagnose heart diseases.
1927 – Herman Blumgart
discovery of artificial radioactivity
Frederic Joliot-Curie and Irene Joliot-Curie; 1934
discovery of Fe-59
John Livingwood, Fred Fairbrother, Glenn Seaborge; 1937
an artificial element to fill space number 43 in the periodic table
Technetium 99
Technitium 99m discovered by
C. Perrier and E. Segre; 1937
The building block of a radiographer’s understanding of interactions between ionizing radiation and matter
atom
Came from the Greek word, “atomos” which means _______
indivisible
Smallest part of an element that has all the properties of that element.
atom
The basic component and the smallest unit of matter
atom
it is neutrally charged because the number of protons is equal to the number of electrons
atom
Central core of an atom
nucleus
Contains nearly all the mass of an atom
nucleus
Positively charged
Contains the nucleons (protons+neutrons)
nucleus
Composed of electrons, which is negatively charged.
Orbits / Shells
Positively Charged and has an atomic mass of 1
Proton
no charge or Neutrally charged and has an atomic mass of 1
neutron
negatively charged and the lightest among the subatomic particles
electron
atomic mass of 1/1836 or approximately________
1/2000
the smallest chemical unit of an element or compound that exist independently
molecule
what year: discovery of radioactivity
1896
The property of certain nuclides to spontaneously emit radiation in form of alpha, beta, and gamma rays and other nuclear fragments to reach a stable state.
radioactivity
who discovered radioactivity
Antoine Henri Becquerel
