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...

What occurs during Coherent Scattering? -----CORRECT ANSWER----The incident xray interacts with an atom causing it to become excited. The atom immediately releases this excess energy as a scattered x-ray having the same energy and wavelength as the incident x-ray, but in a different direction. What occurs during Compton Scattering? -----CORRECT ANSWER----The incident xray interacts with an outer-shell electron and ejects it from the atom, ionizing the atom. The x-ray then continues in a diff...
