LRA 211 Latest Update with Verified Solutions The three fundamental particles of the atom are the proton, neutron, electron The atomic nucleus contains protons and neutrons The component of the nucleus that has a positive charge and mass is the protons The component of the nucleus that has mass but no electrical charge is the Neutron If an atom has more electrons than protons, it will Negative When an atom becomes negatively or positively charged it is usually due to a change in the number ...

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...
