Top-view tubes

122P224

The 122P224 Nixie tube (or B5092A) was made by Burroughs of the United States, so this is a genuine branded Nixie tube. This tube is special because it has Krypton 85 added, which is a radioactive isotope of Krypton that emits alpha particles. These keep the Neon ionized and so help reduce the time it takes the tube to 'ignite', especially in dark conditions.
