1. define radon - ANSWER Radon is a colorless, odorless, radioactive gas. It
forms naturally from the decay (breaking down) of radioactive elements,
such as uranium, which are found in different amounts in soil and rock
throughout the world
2. _____ are the extremely small particles of which we, and everything around
us, are made.
A. Radon
B. Particles
C. Ions
D. Atoms - ANSWER D. Atoms
3. Radiation that falls within the "_____" range has enough energy to remove
tightly bound electrons from atoms, thus creating ions, and this is the type of
radiation that people usually think of as 'radiation.'
A. non-ionizing radiation
B. ionizing radiation - ANSWER B. ionizing radiation
4. _____ particles include two protons and two neutrons.
A. Beta
B. Gamma
C. Alpha - ANSWER C. Alpha
5. We're really concerned with the _____ particles, because they can be
stopped by a sheet of paper where they release their energy.
A. gamma
, B. x-ray
C. alpha
D. beta - ANSWER C. alpha
6. T/F: Radon is a light gas and tends to collect in high areas of houses such as
attics.
A. False
B. True - ANSWER A. False
7. T/F: Some decay products of radon emit beta particles, but its alpha-emitting
decay products pose a much _____ health risk.
A. lesser
B. greater - ANSWER B. greater
8. _____ photons can pass through many kinds of materials, including human
tissue.
A. Gamma
B. Alpha
C. Beta - ANSWER A. Gamma
9. Most naturally occurring radioactive materials and many fission products
undergo radioactive decay through a series of _____ (loss of particles or
electromagnetic energy from an unstable nucleus) rather than in a single
step.
A. misinterpretations
B. reflections
C. transformations
D. growth spurts - ANSWER C. transformations
10._____ are the source of cell damage in the lungs.
A. Radium elements
B. RDPs
, C. Uranium material
D. Radon elements - ANSWER B. RDPs

roughly the size of a _____.
A. submarine
B. pea
C. airplane
D. building - ANSWER B. pea
12.T/F: The balance of the forces in the nucleus of an atom determines whether
a nucleus is stable or unstable (radioactive).
A. False
B. True - ANSWER B. True
13.As an unstable nucleus emits radiation as it disintegrates, the radionuclide
transforms to different nuclides, and this process is called _____.
A. radioactive development
B. radioactive decay
C. radon gas mitigation
D. radio transmission - ANSWER B. radioactive decay
14.A _____ refers to the series of transformations that a given radionuclide will
undergo, as well as the kind of radiation it emits, which are characteristic of
the radionuclide.
A. radon mitigation
B. decay chain
C. radiation
D. radon curies - ANSWER B. decay chain

decay.
A. Radiation
B. Ioning
C. Atomizing
D. Disintegration - ANSWER A. Radiation
17._____ is the property of an atom that describes spontaneous changes in its
nucleus that create a different nuclide, and these changes usually happen as
emissions of alpha or beta particles, and often gamma rays.
A. Atomic weight
B. Gaseous emission
C. Radioactivity
D. Decay chain - ANSWER C. Radioactivity
