# § 5114. Air transportation of ionizing radiation material

**(a)** **Transporting in Air Commerce.—** Material that emits ionizing radiation spontaneously may be transported on a passenger-carrying aircraft in air commerce (as defined in section 40102(a) of this title) only if the material is intended for a use in, or incident to, research or medical diagnosis or treatment and does not present an unreasonable hazard to health and safety when being prepared for, and during, transportation.

**(b)** **Procedures.—** The Secretary shall prescribe procedures for monitoring and enforcing regulations prescribed under this section.

**(c)** **Nonapplication.—** This section does not apply to material the Secretary decides does not pose a significant hazard to health or safety when transported because of its low order of radioactivity.
