About two months ago I had a raduim Looping desk alarm clock which fell on the floor from about 3 ft for those last few days i had been using it as an alarm clock and it was working great, but as someone new to clock collectiong I didn't know it was raidoactive. When the clock fell I was sleeping so i don't know how long I was exposed, but i think that it was on the crystal when it fell but im not quit sure. When i woke up i saw the clock on the floor, and beeing stressted that it had broke i quickly put the crystal back on the cloock and put it back on my desk. for the following week or so I contuinued with my life. Sometimes I thought about how the clock might be raidoactive but if it didn't glow in the dark I thought I was fine. One day I was curious and I used a UV light and realized it glowed this made me verry stressed, I read a couple articles about how dangerous radium watches were and if the crystal is taken off and exposed to you in a closed space it can become verry dangerous so, for the following week I slept in a different room and got a gigercounter just to confirm that it was radioactive and it was. Then I took it to a local clock repairman to see his reaction to the story and he said that it was fine but I am still worried because there might still be radation im my room especaily if some radon leaked out.
I would love to know what kind of advice is out there about broken radium clocks and their saftey I really don't know where to go or what to do at this point. Currently, the cloock is safely stored to prevent anymore radation leakage. Also I radation cheked my room with the giger counter to see it it was radioactive and it was normal but i cannot confirm because it does not detect alpha radation.
