Where is the isotope sample in Fallout 4?
The isotope sample in Fallout 4? You'll find it in the Cambridge Polymer Labs. Once inside, you gotta complete a series of quests that involve getting locked in the lab. The sample you're looking for is U-238, and it's sitting right there on a table inside the isotope containment chamber. Just make sure you're ready to handle some feral ghouls and a bit of puzzle-solving!

Quick answer: Cambridge Polymer Labs, inside the isotope containment chamber. Look for U-238; can't miss it unless you're too busy fighting off ghouls.
Found it after an embarrassingly long time wandering around. It's in the Cambridge Polymer Labs for real, just like everyone says. Thought I could sneak around the quest, but nope, you gotta do the work and get through the quest line in the lab. That isotope sample is key for some cool crafting, so grab it and run!
