who knows what these are?
These are TLD badges they basically measure radiation levels on people. My husband and I wore these when we were in teh military and we were non-destructive testing inspectors and used x-ray on aircraft to look for cracks.
easy one right? geiger meters to measure radiation levels.
where can you find this and much more?
well here of course:
at the atomic testing museum in las vegas:
a fun and interesting museum about the atomic energy era, how it started, and all kinds of other stuff.
