eliminate contamination spread.
Engineered controls are devices such as
glove boxes, glove bags, portable filtration
units, and containment tents. They should
be used to prevent worker inhalation of
radionuclides.
Portable and fixed/permanent shielding using
dense materials (lead) or portable plastic
interlocking fluid filled containers are also
engineered features, used to minimize
external radiation dose.
