Matter - Anything that occupy space and has mass
Mass - Distinguishable characteristic of matter
Mass - Quantity of matter that is described by its energy equivalent
Atoms - All matter is composed of fundamental building blocks
Kilograms - How is mass measured?
Meters - What does length measure?
Seconds - What does Time measure?
Weight - Force on a body caused by the pull of gravity on it
Energy - Ability to do work
,Potential Energy - The ability to do work by virtue of position
Kenetic Energy - The energy of motion
Chemical Energy - Released by a Chemical reaction
Electrical Energy - Represents the work that can be done when an electron moves through
an electric potential difference (voltage)
Thermal Energy - The energy of motion at the molecular level. (heat)
Nuclear Energy - Energy that is contained within the nucleus of an atom
Electromagnetic Energy - Is a form of energy that can be reflected or emitted from objects
through electrical or magnetic waves traveling through space.
Radiation - Energy emitted and transferred through space
X-rays, Ultraviolet radiation, Visible light, Microwaves, Radio waves and Infrared radiation -
Examples of electromagnetic energy
Clue: X,UR,VL,M,RW & IR
Irradiated or Exposed - Matter that intercepts radiation and absorbs part or all of it.is said to
be
Bequerel (Bq) - Unit of Radioactivity
, Bequerel (Bq) - Unit of Quantity of Radioactive Material
Sievert (Sv) - The unit of occupational radiation exposure and effective dose
Sievert (Sv) - Use to Express the Quantity or Radiation received by radiation workers and
population
Gray (Gy) - Unit of Radiation Absorb Dose
Air Kerma - Kinetic Energy transferred from photons to electrons during ionization and
excitation
Thermal Radiation - Transfer of heat by the emission of infrared radiation
