Radiological Control
Radioactive Materials
June 2004
3.
Radioactive material with removable or potentially removable contamination levels in excess of 100 times Table 2-2
values should have additional packaging controls such as double -wrapping or the use of plastic bags inside
containers.
4.
Yellow plastic wrapping material (or plastic wrapping materials emblazoned with yellow markings) should be used for
packaging radioactive material and should not be used for non-radiological purposes.
5.
The amount of combustible material used in packaging should be minimized.
414 Radioactive Material Storage
1.
Radioactive material in quantities exceeding the applicable Appendix 4A quantities shall be used, handled, and
stored in a radioactive material area or other area posted in accordance with Article 234 or 235, as appropriate [see
835.2(a), radioactive material area, and 835.603].
2.
Decontamination or disposal of radioactive material is the preferred alternative to long-term storage.
3.
Each radioactive material area should be appro ved by the radiological control manager or designee.
4.
A custodian should be assigned responsibility for each radioactive material area. A custodian may have
responsibility for more than one storage area.
5.
The custodian should conduct walk-throughs o f radioactive material areas at least monthly to check integrity of
containers and wrapping materials.
6.
The custodian should conduct annual or more frequent reviews of each radioactive material area, with emphasis on
treatment, decontamination, movement of material to long-term storage locations, and disposal of unneeded material.
7.
Storage of non-radioactive material in a radioactive material area is discouraged.
8.
Outdoor storage of radioactive material is discouraged. In cases where outdoor stora ge is necessary, the integrity
of containers or wrapping materials used should be ensured to prevent degradation from weathering and
subsequent release of radioactive material.
9.
Radioactive material should be stored in a manner that reduces combustible loading. The use of cardboard
containers for storage is discouraged.
10.
Flammable or combustible materials should not be stored adjacent to radioactive material areas.
11.
Fire protection measures, such as smoke detectors, water sprinklers, and fire extinguishers, should be considered
when establishing a radioactive material area.
