Mr RADical

 (named Scavenger in-game) was a scavenger in 2281.

Background
Mr. RADical found an Advanced radiation suit (sometimes not in advanced radiation suit, just a normal one) and started testing it out in highly irradiated places. When he found out how well it worked he started doing more dangerous things with his suit. He even planed on taking a batch of Isotope-239 igniting agent and dumping it on himself. Mr. RADical's Journal can also be found on his corpse. It is presumed that he didn't dump the Isotope on himself and died from radiation poisoning (his journal states he became sick on day 5) since the player finds a full jar of the Isotope on his body.

Appearances
appears only in Fallout: New Vegas.

Bugs
He will spawn halfway underground. Grabbing him with R3 will make him fall through altogether, making the only way to complete the quest by getting 5 Rocket souvenirs.
