A radiologic technologist is working on barium and iodine. Which term does the radiologic technologist use to refer to 134/56 Ba and 131/53 I ? a. Isobar b. Isomer c. Isotope d. Isotone - Correct d. Isotone Isotones differ in their atomic numbers and mass numbers, but they have the same number of neutrons, that is, a constant for the quantity a (atomic number) - z (mass number) a-z. Types of ionizing radiation used in various techniques have different ranges of penetrability into the s...
