  1. a unit of measurement for absorbed dose. It measures the amount of energy absorbed in a material. The unit Gy can be used for any type of radiation, but it does not describe the biological effects of the different radiations. For more information, see “Primer on Radiation Measurement” at the end of this document.
  2. a unit used to derive a quantity called dose equivalent.
  3. Acronym for “as low as reasonably achievable,” which means keeping the radiation dose as low as possible when performing medical imaging procedures.
  4. uses high-frequency sound waves to create images of organs, tissues or blood flow.
  5. electromagnetic radiation caused by deflection of electrons from their original paths, or inner
  6. a heavy metal. Several isotopes of lead, such as Pb-210 which emits beta radiation, are in the uranium decay chain.
  7. A unit of absorbed radiation equal to one thousandth of a gray, or 0.1 rad.
  8. electrons that change their orbital levels around the atomic nucleus.
  9. This test uses a small transducer that produces high-frequency sound waves, which create detailed images of the heart.

  1. in radiology refer to something seen on an image that are not present in reality but appear due to a quirk of the modality itself.
  2. X-ray imaging of the heart, coronary arteries, and/or great vessels made visible by injection of a dye directly into the vessel via a catheter. In other instances, CT or MRI can be used to create three-dimensional pictures of blood vessels.
  3. a small portable instrument for measuring and recording the total accumulated dose of ionizing radiation a person receives.
  4. radiation A very high frequency form of electromagnetic radiation that consists of photons emitted by radioactive elements. Gamma rays can injure and destroy body cells and tissue, especially cell nuclei.
  5. a measure of ionization in air caused by x-rays or gamma rays only. The unit of exposure most often used is the roentgen.

14 Clues: a unit used to derive a quantity called dose equivalent. • electrons that change their orbital levels around the atomic nucleus. • A unit of absorbed radiation equal to one thousandth of a gray, or 0.1 rad. • uses high-frequency sound waves to create images of organs, tissues or blood flow. • ...
