2 Omega Seamaster Calendar - Radium hands?

We’ll both hand sets look incorrect for the watches so although they would’ve had radium hands originally it’s hard to be sure now.
Only the first watch seems to have radium on the dial.

Given the wrong hands and poor dial on the second, hopefully they were very cheap. Condition, condition, condition.

I wouldn't worry too much. Not that radium isn't dangerous, but the odds that you were seriously exposed to a high concentration of disintegrated radium lume particles and/or radon gas is quite low. In the future, it's wise not to open any watch manufactured before 1962 or so - leave them to your watchmaker. If you are going to be a serious collector of vintage watches, it's also a good idea to have a portable geiger counter in your stable of tools. And don't let the fact that a watch dial or hands have radium prevent you from buying a watch that you like. The danger is very small as long as the watch case and crystal are intact and some radium dialed watches are simply stunning in appearance. Here's my 1958 Ranchero which has radium lume on both the dial and hands.

Radium would be higher than 0.19 uSv/hr. That would be considered background.
I think the lowest I’ve seen is around 0.5 for radium up to a factor of ten higher.

You have to put your gonads in a bowl with ice cubes and 3 iodine tablets diluted in water.

Do this 3 times a day for 45 minutes.
