Now, a virtual version of that helmet can be worn in Fallout 4 thanks to a mod uploaded by Nexus Mods user Herby247, and rather aptly, it'll give you constant radiation poisoning if you wear it.

Naturally, a modder has added the moldy power armor helmet to Fallout 4. The Moldy T-51 Helmet mod adds a helmet that, when worn, will give your character constant radiation damage.
