Tangent of the actual question, but with a spinning object, the parts furthest away from the center of rotation should experience a time shift relative to the parts at the center of rotation, right?

For example a large disk of radioactive material spinning - the radioactivity at the outside edge would decay faster than the radioactivity at the center?

I thought the edge of a disc would decay slower, since they're going closer to accelerating to lightspeed, therefore they're the ones experiencing time dialation?
