i just googled sea mist green fiestaware mug and got this. had a good chuckle.
Fiesta dinnerware made from 1936-1972 may be radioactive. You can buy modern Fiesta ceramic dishes in just about any color of the rainbow, though the modern colors won't match the old colors. None of the dishes contain lead or uranium. None of the modern dishes are radioactive.

The Orange, (AKA "Red") and creme are very active with Uranium. Some trace radioactivity in some of the other glazes but not as much for sure.
I have a bit, my wife collected it and I used it in training to show how common objects that have natural radioactivity. the greens don't seem to have any detectable activity from my collection.
I wouldn't trust anything vintage for lead content, however I am not afraid of lead too much with all the lead projectiles and fishing sinkers I made.
