Special Quantities - ANSWER: - Exposure (R) (Gy)
- Dose (rad) (rem) (Sv)
- Radioactivity (Ci) (Bq)
Newton's First Law of Mechanics (Inertia) - ANSWER: A body will remain at rest or
continue to move with constant velocity in a straight line unless acted upon by an
external force
Newton's Second Law of Mechanics (Force) - ANSWER: The force on an accelerating
object is equal to mass multiplied by the acceleration (F = ma)
Newton's Third Law of Mechanics (Action & Reaction) - ANSWER: For every action
there is an equal opposite reaction
Work - ANSWER: Joule
Energy - ANSWER: is the ability to do work; Erg, Joule

Exposure (Roentgen/R) or Air Kerma (Gya) - ANSWER: The kinetic energy transferred
from photons to electrons during ionization and excitation
Absorbed Dose (Rad) or Gray (Gyt) - ANSWER: Radiation energy absorbed per unit
mass; depends on the type of tissue being irradiated
Effective Dose (Rem) or Sievert (Sv) - ANSWER: The quantity of radiation received by
radiation workers and populations as well as patient dose (occupational radiation)
Radioactivity (Curie/Ci) or Becquerel (Bq) - ANSWER: The unit of quantity of
radioactive material, not the radiation emitted by that material
