Whole decision: Granted

The Board finds that the Veteran's in-service radiation exposure was higher than previously documented, and this increased exposure is considered to be a substantial factor contributing to his death from colon cancer. The cause of death is therefore service-connected.

The deciding factor: Competent lay evidence suggests higher levels of in-service radiation exposure compared to what is recorded on the Veteran's DD Form 1141, which undermines negative nexus opinions based solely on the documented totals.
