Week 7: Gamma Rays and Microbial Genetics For this discussion, I chose Topic 1 Pro Gamma Irradiation of Food. ▪ Would you eat gamma-irradiated strawberries? ▪ Gamma-irradiation does extend the shelf-life but after some time, mold does begin to grow. Where does the mold come from? ▪ Was the mold already present on the strawberries and the growth slowed by the gamma irradiation? ▪ If gamma irradiation becomes the standard for processing produce, over time will the constant radiation e...

Electronic beam: 3.5" of penetration What are the main factors that help achieve the desired dose? - Answer 1. Duration of exposure 2. Location of product to source

Instrumentation NMTCB Practice with Certified Solutions What is a gamma camera crystal made of? Sodium iodide activated with thallium What is the purpose of the crystal in a gamma camera? To absorb gamma (γ) rays and convert them into visible-light photons What is the mechanism by which gamma (γ) rays interact with a gamma camera crystal? Photoelectric effect or Compton scattering. What is the relationship between the energy of an absorbed gamma (γ) ray and the amount of light produced by...

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...
