ionizing radiation- often knock off electrons through
What is nuclear radiation often
called? Compton scattering, photoelectric effect and
electron-positron pair production
a scattering of high-energy photons, such as gamma
What is Compton scattering? rays, by a nucleus. Like colliding billiard balls. Led to
discovery of particle-like properties of photons.
Interactions
create a free electron with high energy that produce ionization
What is exposure? The total electric charge on the ions produced in a given mass of
air
The common unit for exposure. One roentgen is the
What is a roentgen?
exposure resulting in an ionization of 1 electrostatic unit
in 1 cubic centimeter of air at 0 c and 1 atm.
What does the severity of dose received, dose equivalent, quality factor, nuclei
radiation depend on?
Why are alpha, beta and Ionize water, humans are 80% water. Ions are very
gamma ray radiation chemically reactive and can react to biological cells.
harmful? Thus damage DNA and cause cancer
What makes alpha radiation Alpha lose energy relatively faster than beta and gamma
more potent? radiation.
What is the quality factor? Energy deposited per unit of path length.

Both have unstable nuclei that emit an alpha or beta
How are beta and alpha decay
similar? particle in order to try to become more stable nuclei.
Who discovered alpha decay? Ernest Rutherford in 1903
How did Rutherford measure By deflecting alpha particles from decay of radium in electric and
the charge to mass ratio? magnetic fields.

When did Rutherford prove 1909
that alpha
particles are helium nuclei?
What was Rutherford's thin- No air molecules inside the chamber. Alpha particles

a nucleus lets go of an alpha particle. The nucleus of
What is alpha radiation like?
helium is such a tightly bound system that the KE is at
its max
an electron is emitted by a radioactive nucleus. Electron
What is Beta Decay?
carries a negative charge and the system must
compensate for the change. A neutron or proton
changes.
What confirmed the origins of The discovery of neutrino and works of Enrico Fermi and
beta decay? Wolfgang Pauli
What is the relationship fairly intuitive, if a neutron is added then a proton is
between protons and removed. If a neutron is removed than a proton has to

What accompanies alpha and gamma decay
beta decay?
During alpha or beta decay the resultant nuclei end up in
What causes gamma decay?
excited states. These nuclei fall back into the ground
state by emitting gamma radiation or gamma particles.
High frequency, high energy, high penetration depth,
