Murdoc asks: “How do they verify that an applicant is eligible for this plate? With a Geiger counter?”
Apparently not, according to Eric Felten of the Wall Street Journal:
And Alabama offers what has to be the single most bizarre plate on the road today, a tag that reads “Atomic Nuked Veteran.” Those who would like to advertise this particular fact of their personal history must get a letter of verification from the Defense [Threat Reduction] Agency proving that they “were exposed to dangerous levels of radiation due to atomic bomb and weapons tested from 1946 to 1962.” No Geiger count is required.
