The player character must give Senior Scribe Neriah 20+ blood samples in the unmarked quest Blood Bank , and then talk to her again. She will give the player character 6 X-111 compounds and will inform them that if they want more they need to bring her more viable blood samples.
The X-111 compound was created by Scribe Neriah of the Brotherhood of Steel by analyzing the blood chemistry of mutated creatures to better understand how their bodies handle excess radiation. Named after the Vault from which the Sole Survivor hails, the compound allows for a human to purge their body of radiation much more effectively than RadAway by mimicking the cleansing processes that occur naturally in the bodies of mutated creatures.
