Package meets general design requirements for radioactive material packaging from

49 CFR 173.410

- Nonfixed/removable contamination on the external surface of the package is < limit

in 49 CFR 173.443 (0.41 Bq of tritium/cm2 or 22 disintegrations/min (dpm)/cm2 for

tritium)

- Outside of inner or outer packaging is marked "Radioactive"

Low Specific Activity (LSA) A quantity of Class 7 (radioactive) material with limited

specific activity

- LSA-I

Earth, concrete, rubble or other debris = 4 x 105 TBq of tritium/g (0.001 Ci of

tritium/g, 1 Ci of tritium/kg or 2.2 lb/Ci of tritium)

- LSA-II

Tritium-Contaminated Water up to: 0.8 TBq of tritium/L (20.0 Ci/L)

Solids and Gases up to 0.004 TBq of tritium/g (0.1 Ci/g, 100 Ci/kg)

Liquids 4 x 104 TBq of tritium/g (0.01 Ci/g, 10 Ci/kg)

- LSA-III

Solids, consolidated wastes, or activated material that meet 49 CFR 173.468

water leach test; and

Uniformly distributed in a collection of solid objects or uniformly distributed in

solid compact binding agent; i.e., concrete, bitumen, ceramic, etc.

Relatively insoluble or intrinsically contained in relatively insoluble material such

that, under loss of packaging and placed in water for seven days, would not

exceed 4 TBq of tritium (108 Ci of tritium)

The average specific activity of the solid does not exceed 0.08 TBq of tritium/g

(2.16 Ci/g)

SCO (Surface Contaminated Object) Non-radioactive solid objects with Class 7

(radioactive) materials distributed on the surfaces

- SCO-I

Nonfixed contamination on accessible surface averaged over 300 cm2 is < 4 Bq

of tritium/cm2 (104 Ci/cm2 )

Fixed contamination on the accessible surface averaged over 300 cm2 is < 4 x

104 Bq of tritium/cm2 (1 Ci/cm2 )

Nonfixed plus fixed contamination on the inaccessible surface averaged over 300

cm2 is < 8 x 105 Bq of tritium/cm2 (20 Ci/cm2)

- SCO-II

Solid object on which limit for SCO-I is exceeded and meets the following:

Nonfixed contamination of accessible surface averaged over 300 cm2 is < 400 Bq

of tritium/cm2 (10-2 Ci/cm2).

Fixed contamination of accessible surface averaged over 300 cm2 is < 8 x 105 Bq

of tritium/cm2 (20 Ci/cm2).

Nonfixed plus fixed contamination of accessible surface averaged over 300 cm2

is < 8 x 105 Bq of tritium/cm2 (20 Ci/cm2).
