Areas

Defining Condition

Controlled Area

Means any area to which access is managed to

protect individuals from exposure to radiation

and/or radioactive material.

Radiation Area

Means any area accessible to individuals in

which radiation levels could result in an

individual receiving a deep dose equivalent in

excess of 0.005 rem (0.05 millisievert) in 1

hour at 30 centimeters from the source or from

any surface that the radiation penetrates.

High Radiation Area

Means any area accessible to individuals, in

which radiation levels could result in an

individual receiving a deep dose equivalent in

excess of 0.1 rem (0.001 sievert) in 1 hour at 30

centimeters from the radiation source or from

any surface that the radiation penetrates.

Very High Radiation Area

Means any area accessible to individuals in

which radiation levels could result in an

individual receiving an absorbed dose in excess

of 500 rads (5 grays) in 1 hour at 1 meter from

a radiation source or from any surface that the

radiation penetrates.
