My tritium has expired

It’s a little difficult to read the sticker due to reflection, but apparently this tritium—manufactured in 1988—expired in 1999. It’s half-life is just over 12 years, so I don’t think it has truly “expired,” but I do wonder about the casing. I should probably look up how to locally dispose of radioactive materials.
