Recently I purchased a watch containing radium on the dial (knowing it had radium paint). I was under the impression that this practice is safe as long as the watch is not opened. After first inspection the case seemed tightly sealed. For a couple days I kept it on a small table a little ways from my bed. Just today I removed the watch from the table in order to store it in a safe container. When I went over the table with a Geiger counter (with the watch removed and away from the table), I got a similar reading as if it was still sitting on the table. Is this an indication that the case/crystal may have been compromised and the paint was outside the watch? I then proceeded to wiping the surface with a dampened towel and paper towels. Despite all my cleaning efforts, the Geiger counter was giving similar readings afterwards. Will the radiation reading dissipate over time if I leave my window open some time or should I be concerned over residual paint on the table? Is there a possibility I inhaled some radium particles? Does anyone have any advice how to clean the table if it is contaminated? This may not be the right place to ask these questions but any help would be appreciated as at this point I just want to prevent any further damage I may have already caused myself.
