On 03/03/04 the
Texas National Guard discovered that one of their M1A1 tanks which was stored in a outside fenced area at their Army training facility in Wylie,
Texas was missing a
tritium beam splitter from its muzzle reference sensor. A thorough search was made of the entire area with negative results and a wipe of the tank also tested negative. The beam splitter contained a sealed 10 curie
tritium source. All of the other tanks stored in the same fenced area with the one having the missing source were inspected and found to be intact.
- * * RETRACTION AT 1030 ON 2/26/04 GIZICKI TO RIPLEY * * *
Following reinspection, it was determined that the tritium beam splitter was not missing from the muzzle reference sensor. The individual who conducted the initial inspection could not see the illumination in the day light. When it was reinspected in a dark area, appropriate illumination was noted. Therefore the source was still in the beam splitter.
