Question Number: 399 Detection and Measurement In NTE (nuclear track emulsion) film, the tracks are caused by: A) alpha particles. B) beta particles. C) gamma photons. D) recoil neutrons. E) recoil protons. correct answers The correct answer is: E In this fast neutron responsive dosimeter, recoil protons from elastic scattering with hydrogen atoms in the film create short "tracks" of ionization as stable silver atoms are created. These tracks are counted either by eye or mechanica...

Exam three study guide Pathway oÿ the respiratory system: (upper respiratory) Nasopharynx → oropharynx → pharynx → epiglottis → larynx → trachea → (lower respiratory) bronchi → bronchioles → alveolar ducts → alveoli. Mediastinum separates lungs, diaphragm contracts with inhale and relaxes with exhale. Contains the pleura space and the ribs. Ventilation is the movement oÿ air into the lungs Elastic recoil is the recoiling oÿ the lungs returning to normal size ...
