Surface contaminated objects

For transportation Surface-contaminated objects (SCOs) are of special interest SCO means a solid object which is not itself radioactive but which has radioactive material distributed on its surfaces. SCO is classified in one of two groups ... 

Less dangerous radioactive materials permit less stringent packages. Specifically, Industrial Package Types 7, 2, and 3 are in use for low-specific activity (LSA) materials and surface-contaminated objects (SCO) ... 

Radioactive materials are grouped according to their form and/or characteristics. These include Special Form Low Specific Activity (LSA) Surface Contaminated Object (SCO) Fissile Other Form. A radioactive material may meet the definition of one or more of the above. lATA 10.3.3... 

Offering Class 7 low specific activity (LSA) materials or surface contaminated objects (SCO) while failing to comply with applicable transport requirements (including, an external dose rate that exceeds an external radiation level of 10 mSv/h at 3 meters from the unshielded material). 173.427 7,500 to 12,500. 

A differentiation is made between two categories of surface contaminated objects (SCOs) in terms of their contamination level, and this defines the type of packaging to be used to transport these objects. The Regulations provide adequate flexibility for the unpackaged shipment of SCO-I objects or their shipment in an... 

Surface contaminated objects are by definition objects which are themselves not radioactive but have radioactive materials distributed on their surfaces. The implication of this definition is that objects that are radioactive themselves (e.g. activated objects) and are also contaminated cannot be classified as SCOs. Such objects may, however, be regarded as LSA material insofar as the requirements specified in the LSA definition are complied with. See also para. 226.19. 

Conveyances may become contaminated during the carriage of radioactive material by the non-fixed contamination on the packages. If the conveyance has become contaminated above this level, it should be decontaminated to at least the appropriate limit. This provision does not apply to the internal surfaces of a conveyance provided that the conveyance remains dedicated to the transport of radioactive material or surface contaminated objects under exclusive use (see para. 514.1).
