nuclear Flashcards
_______occurs when an atom releases both energy
and particles.
Radioactivity
_________occurs when an unstable nucleus of an atom emits
radiation.
E-mats
Emits
radioactive decay
nuclear charge is
atomic number
the term______ is used
instead of isotope
nuclide
________are slower moving particles and are blocked
by thin barriers.
Alpha
________occurs when an alpha particle is released upon
decomposition of a nuclide.
Alpha Decay
______occurs when a beta particle is released upon
decomposition of a nuclide.
Beta Decay
_________occurs when a beta particle with a
positive sign is emitted from a decomposing nuclide
Positron Emission
________can emit from decomposing nuclides as pure
energy.
Gamma Ray Emission
_________ usually emitted along with other forms of
nuclear decay.
gamma rays
Radioactive decay loses its potency in a couple of ways:
Increasing Distance
Shielding
Time Reduction
sheel-ding
shielding
The intensity of radiation decreases with the square of the distance
Increasing Distance
Shielding
Using materials like lead, concrete, or water to absorb or block radiation.
Time Reduction
Minimizing the time of exposure to radiation reduces the total dose received.
