PART 175_CARRIAGE BY AIRCRAFT--Table of Contents
 
Subpart C_Specific Regulations Applicable According to Classification of 
                                Material
 
Sec. 175.700  Special limitations and requirements for Class 7 (radioactive) 
materials.

    (a) In addition to other requirements, no person may transport in a 
passenger-carrying aircraft any package required to be labeled in 
accordance with Sec. 172.403 of this subchapter with a RADIOACTIVE 
YELLOW-II, RADIOACTIVE YELLOW-III or FISSILE label unless:
    (1) For a package required to be labeled RADIOACTIVE YELLOW-III, the 
transport index does not exceed 3.0;
    (2) For a package required to carry a FISSILE label, the criticality 
safety index does not exceed 3.0;
    (3) The package is carried on the floor of the cargo compartment, or 
freight container;
    (4) The package is carried in the aircraft in accordance with 
Sec. Sec. 175.701 and 175.703;
    (5) The total sum of transport indices of all packages in the 
aircraft does not exceed 50; and
    (6) The total sum of criticality safety indices of all packages in 
the aircraft does not exceed 50.
    (b) In addition to the reporting requirements of Sec. 171.15 of 
this subchapter, the carrier shall also notify the offeror at the 
earliest practicable moment following any incident in which there has 
been breakage, spillage, or suspected radioactive contamination 
involving Class 7 (radioactive) materials shipments. Aircraft in which 
Class 7 (radioactive) materials have been spilled may not again be 
placed in service or routinely occupied until the radiation dose rate at 
every accessible surface is less than 0.005 mSv per hour (0.5 mrem per 
hour) and there is no significant removable radioactive surface 
contamination as determined in accordance with Sec. 173.443 of this 
subchapter. When contamination is present or suspected, the package and/
or materials it has touched must be segregated as far as practicable 
from personnel contact until appropriate radiological advice or 
assistance is obtained. The Regional Office of the U.S. Department of 
Energy or appropriate State or local radiological authorities can 
provide advice or assistance, and should be notified in cases of obvious 
leakage, or if it appears likely that the inside container may have been 
damaged. For personnel safety, the carrier shall take care to avoid 
possible inhalation, ingestion, or contact by any person with Class 7 
(radioactive) materials that may have leaked or spilled from its 
package. Any loose Class 7 (radioactive) materials and associated 
packaging materials must be left in a segregated area pending disposal 
instructions from responsible radiological authorities.
    (c) Except as provided in Sec. Sec. 173.4, 173.422 and 173.423 of 
this subchapter, no person shall carry any Class 7 (radioactive) 
materials aboard a passenger carrying aircraft unless that material is 
intended for use in, or incident to research, medical diagnosis or 
treatment.
    (d) Type B(M) packages may not be offered or accepted for 
transportation,
