NRRPT Exam Review Questions With Complete Solutions

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. 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 mechanically and equated...

Question Number: 1 Fundamentals of Radiation Protection A low energy alpha detector is usually effective if the detector is distant from the source. A) 1/4 inch B) 1/2 inch C) 1 inch D) 1 1/2 inches E) 2 inches correct answers The correct answer is: A Low energy alpha particles can only travel less than 1/2 inch in air. Therefore, one must be closer than this to detect them. Question Number: 2 Fundamentals of Radiation Protection A sample of I-131 (half life = 8 days) is ke...

Question Number: 699 Applied Radiation Protection For calculating dose to an organ from internal sources, the "specific effective energy" of a radionuclide is BEST described as: A) the energy given off by the radionuclide per unit of radionuclide activity. B) the energy absorbed per unit mass of the organ per unit of radionuclide activity. C) the energy absorbed per unit mass of the organ per disintegration of the radionuclide. D) the energy given off by the radionuclide per disintegr...
