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.

Electromagnetic radiation
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
interactions).
c. Synchrotron radiation: (photons emitted as
the charged particles are accelerated in a
curved path).
