Charlie Mitchell, 88th Civil Engineer Group air force radioactive recycling and disposal civil engineer, points to a lensatic compass at Wright-Patterson Air Force Base, Ohio, Sept. 8, 2016. Each lensatic compass contains a total of 120.0 millicuries of tritium, a radioactive gas that glows in the dark.  After 12 years, the illumination loses its strength and is sent to a recycler, who recovers the tritium and makes new capsules with the proper amount of tritium ion.
