Radiological Training for Accelerator Facilities
c. Muons travel mainly in the direction of the
beam that produced them with very little
deviation from the beam path. They are a
concern directly downstream of targets,
beam dumps, etc. Muons are ionizing
particles and can deliver a very high dose.
d. Muons lose energy only through ionization
and are very penetrating. Large amounts
of earth or steel are typically used to shield
Facility-Specific - Prompt

radiation sources at site.
Identify facility-specific prompt radiation
EO-07 DEFINE radioactivation.
EO-10 IDENTIFY activation
The process by which materials become radioactive is
commonly referred to as "radioactivation" or simply
"activation." Generally, energies above 10 MeV are
needed to activate materials for particles other than
Activated materials emit radiation from
radioactive decay after shut-off of the beam.
