RADIOACTIVE MATERIAL, SURFACE CONTAMINATED OBJECTS (SCO-I), non-fissile or fissile-excepted UN 2913
Schedule source MSC.539(107), Annex 9, Appendix 1, IMSBC Code Amendment 07-23 · pages 376, 377
Description
The radioactivity of SCO-I is low. This schedule includes solid objects of non-radioactive material having a radioactive material distributed on its surfaces which: 1 the non-fixed contamination on the accessible surface, averaged over 300 cm2 (or the area of the surface if less than 300 cm2), does not exceed 4 Bq/cm2 for beta and gamma emitters and low-toxicity alpha emitters, or 0.4 Bq/cm2 for all other alpha emitters; 2 the fixed contamination on the accessible surface, averaged over 300 cm2 (or the area of the surface if less than 300 cm2), does not exceed 4 × 104 Bq/cm2 for beta and gamma emitters and low-toxicity alpha emitters, or 4 × 103 Bq/cm2 for all other alpha emitters; and 3 the non-fixed contamination plus the fixed contamination on the inaccessible surface, averaged over 300 cm2 (or the area of the surface if less than 300 cm2), does not exceed 4 × 104 Bq/cm2 for beta and gamma emitters and low-toxicity alpha emitters, or 4 × 103 Bq/cm2 for all other alpha emitters.
