Specific Beta Dose Control Principles
Surfaces emitting beta radiation are easily shielded
with plastic or other light element materials. Use
of denser mater ials for shi elding of high-ene rgy
beta radiat ion may produce br emsstrahlung X rays
and should be avoided.
Beta dose to the lens of the eye can be reduced by
using safety glasses. Safety glasses are commonly
worn for industrial safety concerns in areas where
uranium is handled. Heavy rubber or leather gloves
are effective in reducing the skin dose to the hand,
but their use must be balanced against other safety
concerns, such as hazards from machinery or loss
of manual dexte rity.
Industrial safety concerns in a uranium facility may be
more hazardous to personnel than exposure to radiation.
Professional radiological control personnel evaluate the
process in the workplace to ensure workers receive the
maximum overall protection from all hazards, not only
with industrial safety and industrial hygiene personnel.
