DOSIMETER in a KEYCHAIN! | '91 BIRI-2 Radiation Detector
Today, we will take a look at the BIRI-2, a keychain indicator of ionizing radiation made in Ukraine in 1991. It is one of the earliest (and smallest) devices of this kind produced after Chernobyl and still works just fine. We conducted a little test-run and believe it can still be helpful in 2024. Of course, our cat decided to participate as well!
