2. Can seamer - Wikipedia

   en.wikipedia.org/wiki/Can_seamer

   Can seamer. A can seamer is a machine used to seal the lid to the can body. The lid or "end" is usually tinplated steel (food) or aluminum (drinks) while the body can be of metal (such as cans for beverages and soups), paperboard (whisky cans) or plastic. The seam formed is generally leak proof, but this depends on the product being canned.

   It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable. The photon energy (energy of a single gamma ray) of ...
