Do not place packages of radioactive material bearing
RADIOACTIVE YELLOW-II or RADIOACTIVE YELLOW-III labels closer
than three feet to an area which may be continuously occupied
by any passenger, rail employee, or shipment of animals; nor
closer than 15 feet to any package containing undeveloped film
(if so marked).
If more than one package of radioactive
materials is present, the distance must be computed from
Figure 1-11 on the basis of the total transport index number
(determined by adding together the transport index numbers on
the labels of the individual packages) of packages in the car.
Ensure adequate transport controls to assure that no Class III
shipment is transported in the same railcar with any other
radioactive material shipment. In loading and storage areas,
segregate each fissionable (fissile) Class III shipment by a
distance of at least 20 feet from other packages required to
bear a RADIOACTIVE label.
Ensure personnel do not remain unnecessarily
in
a
railcar
containing radioactive materials.
Securely block and brace all packages of radioactive material
to prevent movement during transport.
In the case of packages shipped under the exclusive-use
provision, ensure the radiation level does not exceed 2
millirem per hour in any normally occupied position in the
transport vehicle or adjacent railcar.
Survey each exclusive-use railcar used for transporting
radioactive materials with appropriate radiation detection
instruments after each use. A vehicle may not be returned to
service until the radiation dose rate at any accessible
surface is 0.5 millirem per hour or less, and all significant
removable radioactive surface contamination has been removed.
Stencil any exclusive-use car with the words FOR RADIOACTIVE
MATERIALS USE ONLY in letters at least 3 inches high in a
conspicuous place on both sides of the exterior of the car.
Keep the car closed at all times other than during loading and
unloading.
