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

radiological hazards. This is generally done in cooperation

with industrial safety and industrial hygiene personnel.
