Walmart isnt the only retailer getting targeted by the NRC for questionable disposal of tritium-based exit signs. Sixty other companies, including Home Depot HD, Northwest Airlines DAL and Bed, Bath and Beyond BBBY are also facing investigation. And, lest it appear that the government is unfairly targeting commercial and industrial groups, its worth noting that NASA, West Point, the U.S. Postal Service and dozens of other government-owned and administered facilities are also facing investigation by the NRC.
