MSC 85/26/Add.2ANNEX 3Page 264RADIOACTIVE MATERIAL SURFACE CONTAMINATED OBJECTS (SCO-1),non-fissile or fissile-excepted UN 2913DESCRIPTIONThe radioactivity of SCO-1 is low. This schedule includes solid objects of non-radioactivematerial having a radioactive material distributed on its surfaces which:1. the non-fixed contamination on the accessible surface, averaged over 300 cm 2(or the area of the surface if less than 300 cm 2 ), does not exceed 4 Bq/cm 2 for beta andgamma emitters and low-toxicity alpha emitter, or 0.4 Bq/cm 2 for all other alpha emitters;2. the fixed contamination on the accessible surface, averaged over 300 cm 2(or the area of the surface if less than 300 cm 2 ), does not exceed 4 x 10 4 Bq/cm 2 forbeta and gamma emitters and low-toxicity alpha emitters, or 4 x 10 3 Bq/cm 2 for all otheralpha emitters; and3. the non-fixed contamination plus the fixed contamination on the inaccessiblesurface, averaged over 300 cm 2 (or the area of the surface if less than 300cm 2 ), does notexceed 4 x 10 4 Bq/cm 2 for beta and gamma emitters and low-toxicity alpha emitters,or 4 x 10 3 Bq/cm 2 for all other alpha emitters.CHARACTERISTICSANGLE OF REPOSE BULK DENSITY (kg/m 3 ) STOWAGE FACTOR (m 3 /t)Not applicable - -SIZE CLASS GROUPNot applicable 7 BHAZARDLow radioactivity.This cargo is non-combustible or has a low fire-risk.STOWAGE & SEGREGATION“Separated from” foodstuffs.HOLD CLEANLINESSClean and dry as relevant to the hazards of the cargo.WEATHER PRECAUTIONSThis cargo shall be kept as dry as practicable.
