On the topic of blacks playing Fallout, one time while trying to get a quote from these minimum wage security company employees, they conversationally inquired about our past line of work, and we mentioned some garden-variety radioactive immuno-assay type stuff, nothing special really. One of the security drones, this overweight bespectacled black guy, suddenly perked up and eagerly butted in with a joke about how he hoped our office isn't contaminated by too many "rads", smugly adding that he's "kind of a nerd" when explaining to his coworkers that a "rad is the unit they use to measure radiation".
I instantly knew that he only knew this from playing Fallout, as no one who actually works with radiation measures exposure or dosage in rads, it's all been done in Grays and millisieverts for many decades now. The cringe was so strong I involuntarily winced.
