Subject: Radiative clock and watch dials
I just got back from a local radiologist who was kind enough to scan three dials and hands with their calibrated Geiger Counter. The results are as follows: Seikosha Ships Deck Clock dial: 215 millirems per hour at 1" and background noise at 4' Seikosha Hour and minute hands from above clock: 255 millirems per hour at 1" and background noise at 4' Waltham 8 day dial: 130 millirems per hour at 1" background noise at 3' Waltham 8 day dial and watch: 40 millirems at 1" background noise at 1' The technicians comment was: "Wow, these are really *hot*!" So, now the question is what to do. The dials need attention: ie the silvering is 40% gone, the lettering is 20% gone, and it has radioactive paint on it. I wonder if there is a way to remove the paint so that the dial can be conserved without danger to the conservator? Any suggestions?
