Instructor's Notes
3) The beta particle ionizes target atoms due to the force between
itself and the electrons of the atom. Both have a charge of
minus one.
b.
Range
1) Because of its charge, the beta particle has a limited
penetrating ability.
2) The range in air of beta particles depends on the energy of the
beta particle. In the case of tritium (H-3), the range is only an
inch; in the case of phosphorous-32 (P-32) or strontium-90 (Sr-
90), the range is 20 feet in air.
c.
Shielding
Beta particles are typically shielded by plastic, glass, or safety
d.
Biological hazards
1) If ingested or inhaled, a beta emitter can be an internal hazard
when the source of the beta radiation is in close contact with
body tissue and can deposit energy in a small volume of living
body tissue.
2) Externally, beta particles are potentially hazardous to the skin
and eyes.
3) Provide facility-specific information on the additional risks or
concerns from high-energy beta sources (e.g., P-32, Y-90), as
appropriate.
