For domestic transportation only, packaged and unpackaged Class 7 (radioactive) material containing less than an A2 quantity are excepted from the marking and labeling requirements of this subchapter, other than the subsidiary hazard labeling required in § 172.402(d). However, the exterior of each package or unpackaged Class 7 (radioactive) material must be stenciled or otherwise marked “RADIOACTIVE—LSA” or “RADIOACTIVE—SCO”, as appropriate, and packages or unpackaged Class 7 (radioactive) material that contain a hazardous substance must be stenciled or otherwise marked with the letters “RQ” in association with the description in this paragraph (a)(6)(vi); and

All unpackaged material, other than ores containing only naturally occurring radionuclides, must be transported in such a manner that under routine conditions of transport there will be no escape of the radioactive contents from the conveyance nor will there be any loss of shielding;
(2)
Each conveyance must be under exclusive use, except when only transporting SCO-I on which the contamination on the accessible and the inaccessible surfaces is not greater than 4.0 Bq/cm 2 for beta and gamma emitters and low toxicity alpha emitters and 0.4 Bq/cm 2 for all other alpha emitters;
(3)
For SCO-I where it is reasonable to suspect that non-fixed contamination may exist on inaccessible surfaces in excess of the values specified in paragraph (c)(2) of this section, measures shall be taken to ensure that the radioactive material is not released into the conveyance or to the environment; and
