Milky Pure Anti-Rad Tea

Plan the whole route before you pour the milk in. This version is for the long lap: outer crates, the yard, the inside rooms and the walk back out, all on one cup. A Pure Anti-Rad Tea already raises your resistance to radiation a large amount, and three bottles of milk make that effect last longer, by the game's own text.

Picture a duo sweeping a big monument from one end to the other. Nobody wants to stop in a corridor and dig through the inventory while a scientist reloads. So you both drink at the fence, and the tea keeps working while your hazmat suits take the rest of the load.

The creamy version pulls the other way: stronger, but over sooner. It wins when there is one bad room and a quick exit. If you cannot say how long the run will take, the milky cup is the safer bet. A timer that runs out in the last hallway hurts more than protection that is a little softer.

It still only protects. Whatever radiation you bring home stays until a Pure Rad. Removal Tea or pills deal with it.
