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,
