A good question, but no, not very much. I don't wear this watch very often -- maybe two days a month on average -- and it is stored in a large, well-ventilated space. I have just one other watch with radium paint, and it tickles the Geiger Counter at about 1 micro-sievert/h, so the two combined, both worn at about the same frequency and stored in the same place, likely pose a minimal health risk. I'm guessing I face a much greater health risk each day by driving on one of L.A.'s congested freeways -- due to really poor air quality, and the risk of being hit by a crazy/stupid driver.
