Isotope-239 Igniting Agent

Isotope-239 igniting agent is a quest item in Fallout: New Vegas.

Background
The discovery of Isotope-239 and possible military applications the radioactive igniting agent entailed was one of the key reasons for RobCo's hostile takeover of REPCONN Aerospace right before the Great War.

Characteristics
Isotope-239 igniting agent is a fuel used for the rockets at the REPCONN test site in the quest Come Fly With Me. The item is marked as a quest item, and cannot be dropped. The rocket souvenirs sold at the Dino Bite gift shop in Novac contain the same agent inside them.

Locations
Two can be found at Clark Field, one on the corpse of Mr. RADical and one near a dead brahmin.

Behind the scenes
The only nuclide with an atomic mass of 239 and a half life capable of lasting 200 years would be Plutonium-239, a nuclide that can be added to nuclear reactors to reduce the need for enriched Uranium.

Bugs
The Isotope-239 located next to the dead pack brahmin, along with the other items near it, may fall through the map if touched and therefore become unobtainable.
