Lead Belly

"With the Lead Belly perk, you take 50% less radiation every time you drink from an irradiated water source."

- In-game description

Lead Belly is a perk in Fallout 3 and Fallout: New Vegas.

Effects
With the Lead Belly perk, 50% less radiation is taken every time you drink from an irradiated water source. In Fallout: New Vegas, this benefit extends to all irradiated food and drink.

In both games

 * Because both games rely on the same engine as Oblivion, which used floating point numbers even if the player only saw rounded whole numbers, it is highly likely that a source of water that goes (for example) from "1 Rad" pre-perk to "1 Rad" post-perk is still accurately treated internally i.e. 1 Rad versus .5 Rad.
 * At high levels this perk may become redundant; RadAway, Rad-X, and apparel with radiation resistance, such as power armor, become more available and readily obtainable.

In Fallout: New Vegas

 * There is an abundance of clean water, reducing the relative usefulness of the perk, although the benefit is extended to all irradiated food and water.
 * With the addition of Implant Y-3 in Old World Blues, this perk potentially becomes redundant, though is still available much earlier and for free.
