Skyshine is the radiation scattered from air
techniques. As applicable,
molecules. Accelerator-produced skyshine is
discuss the hadron cascade or the
usually neutron radiation, scattered after
radiation field inside the beam
emerging more or less vertically from the
shielded enclosure. It can cause elevated
radiation fields at ground level considerable
distances from the source.
Due to typical facility design, photon skyshine
is usually less of a problem but is a
consideration, particularly where radioactive
materials are stored.
Define the terms.
a. Bremsstrahlung: (photons emitted through
the deceleration of charged particles
passing through matter).
b. Electromagnetic cascades: (multiple
photons emitted through high-energy
c. Synchrotron radiation: (photons emitted as
the charged particles are accelerated in a
