Dosimeters

I doubt many people will know the answer to this question, but still, I'll ask.

 

I recently acquired an OLD (32 years old) dosimeter from the Diefenbunker Canadian museum. It's an old quartz fiber type, 500 millirems. The problem is, I can't see the reading on it. It's not charged, but I thought that I would still be able to see the marker for radiation. So I don't know if it's broken or just off the scale, so I don't want to get a charger unless I know.

 

So, the question is: On this dosimeter, will it just go off the scale or will the thing just break over 32 years, unopened?

they will go off scale without a charge, and after 32 years, it`ll be out of charge!

 

[edit]have a look here, this is an old style aswell, the charge leakage is about 2% per day, 32 years is a long time!

So it probably will work, it's just off the scale?

 

 

Thanks.

There are self-reading ones, you're probably thinking of dosimeter badges.

Hold it... won't it's internal battery be entirely junk? Most nowadays only last about 6 years, and in the 70's, I'd expect less.
