Radiological Training for Accelerator Facilities
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.
Muons lose energy only through ionization and are very penetrating. Large amounts of
earth and steel are typically used to shield muons. Muons travel mainly in the forward
direction of the beam. They are a concern directly downstream of thick targets, beam
dumps, apertures, etc.
(Facility Specific) Identify Prompt Radiation Sources
IDENTIFY prompt radiation sources at site.
EO-07 DEFINE radioactivation.
EO-10 IDENTIFY activation products.
The process by which materials become radioactive is commonly referred to as "radioactivation"
or simply "activation." Material, air, water, and components that are subject to high-energy
prompt radiations (typically with threshold energies above 10 MeV for particles other than
neutrons) may be made radioactive.
Activated materials emit radiation from radioactive decay after shut-off of the beam.
