Where can I find Moira Brown after blowing up Megaton in Fallout 3?

Question

I heard that if you blow up Megaton with the "Atom" you can go back to the destroyed ruins and you will find Moira (Craterside Supply Owner) wandering around as a ghoul. I blew up megaton and I wait around the ruins but I find nothing but huge loads of radiation that ends up poisoning me. I took care of the radiation problem with 100 Medicine skill and Radx but still no Moira? Does anyone know if there is something certain you have to do/complete to trigger her appearence as a ghoul?

Answer 1

From Fallout Wikia

If you decide to blow up Megaton, she will not die; instead she will become ghoulified. If you started the Wasteland Survival Guide quest, or met her to receive an armored Vault jumpsuit, you will have to visit the Megaton Ruins to find her. If you hadn't started it, she can be found in the Underworld, whereupon she will claim she was 'out-of-town' during the detonation, and apparently unaware of her recent affliction. Depending on how you break the news to her, she will either fall into despair or remain positive. Eventually, she will leave for Rivet City and finally Underworld.
