Vault 34 Info.

Your objective for this quest, the Diagnostic Scanning Module, is to be found in Vault 34. Getting in and back out of this Vault is probably the most difficult Vault exploration challenge you'll experience in this game for a variety of reasons. 1. Much like Fallout 3's Vault 87 the entrance is brimming with radiation and 2 as a possible result of the great green glow you'll find approximately 20-30 ghouls of various types inside. Difficult, yes, but the Vault does offer some other rewards in the form of semi and automatic rifles, 3 of each, 2 sniper rifles, a block of C4, a mini gun, a rocket launcher, 2 energy weapons, and grenade launchers to be obtained in the Overseer's quarters. Accessing the Overseer's rooms requires 2 passcodes that you can get from 2 dead scientists, now Ghoulified, that can be found submerged inside the Vault.

Guide for part 1

The first step you should undertake before attempting to enter Vault 34 is to be cured of all your radiation, because that thing is hotter then an Arizona summer. Once free of all RADs you can find the vault north of the NCR's Camp Golf or west of the NCR's Sharecropper farms near New Vegas.

Notes - According to legend, Ceaser's last words were "Et Tu, Brute?" right before he was betrayed by and stabbed to death by his nephew Brutus as well as several others.
