27CE

Experiment 27CE is an experiment the vault physician James performed in 2274. He performed a test on the radiation levels of Vault 101 by exposing the cells in selected vulnerable areas of the Vault's complex to possible radiation leaks. He re-examined the cells after he retrieved them and found that they replicated normally. The experiment proved that radiation is not leaking into the Vault.

The Lone Wanderer reads the notes for this experiment from the medical data system in their Dad's terminal located in the Vault 101 physician's office on August 3, 2274.
