Radiological Training for Tritium Facilities
Student's Guide
Notes
1.
Beta Energy
A very low energy beta is emitted.
2.
Beta Range
Tritium is not an "external" radiation
hazard.
a.
Travels less than 1/4 inch in air
b.
Cannot penetrate through the dead
layer of the skin
c.
Cannot penetrate clothing or
gloves
3.
Half-life
Radioactive half-life = 12.3 years.
F.
X-Ray Production
Tritium betas can produce low energy x
rays. Because the beta particle is of such low
energy the x rays it may produce are not
very penetrating and are not normally
considered a hazard.
