We ran a Geiger Counter over the soft 50% cotton 50% polyester Hulk Mutated Humanoid Kids T-Shirt and worry not; we didn't detect any errant gamma radiation! Luckily we still have vintage styled version of the Hulk on this faux-worn shirt. You can just make up a lie about how you use to wear the Hulk Mutated Humanoid Kids T-Shirt when you were little and people use to ride dinosaurs to work. I tell kids that kinda stuff all of the time!
