DOE Core Test Studying Guide Questions and
Answers 100% Already Graded A+ Excel
specific Ionization - CORRECT ANSWER-# of ion pairs formed by a particle per path length
Linear Energy Transfer - CORRECT ANSWER-the average energy locally deposited in an
absorber resulting from a charged particle per distance of travel
stopping power - CORRECT ANSWER-the absorbers ability to remove energy from a beam of a
charged particle
Range - CORRECT ANSWER-inversely related to the stopping power, charged particle is only
kinetic, it is the average depth of penetration before the charged particle loses all of its kinetic
energy
2 energy transfer for alpha particle - CORRECT ANSWER-ionization and excitation
3 major energy transfer for beta - CORRECT ANSWER-ionizaton, excitation, and
bremsstrahlung
3 major mechanisms by which gamma photon radiation interacts with matter - CORRECT
ANSWER-the photoelectric Effect(imparts all energy to a valence electron, ionizes)
Compton scattering(imparts some of the energy to the electron, also releases an scattered photon
200 kev and 5 Mev)
Pair production(photon is converted to mass, electron and a positron greater than 1.022 Mev)
elastic scattering - CORRECT ANSWER-neutron strikes a nucleus approximately the same size,
cue ball neutron imparts its kinetic energy to the nucleus
Inelastic Scattering - CORRECT ANSWER-the neutron hits a large nucleus fort a short time,
transfers energy to a nucleon inside, then exits with a small decrease of energy, the nucleus is left
excited emitting gamma radiation that can cause ionization and excitation
Law of Bergonie and Tribondeau - CORRECT ANSWER-the radio-sensitivity of a tissue is
directly proportional to its reproductive capacity and inversely proportional to its degree of
differentiation
