Instructor's Notes

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

muons.

Facility-Specific - Prompt

EO-06 IDENTIFY prompt

radiation sources at site.

Identify facility-specific prompt radiation

sources.

Residual Radioactivation

EO-07 DEFINE radioactivation.

EO-10 IDENTIFY activation

The process by which materials become radioactive is

products.

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.
