After a week-long intense search, Australian authorities found a radioactive capsule that was lost two weeks ago. The tiny capsule, which was 6-by-8 mm long or 0.24 to 0.31 inches, was lost along a massive highway stretching 870 miles. Official says the capsule, used to measure the density of iron ore feed from the Gudai-Darri mine in Rio Tinto, fell off a truck. Inside Edition Digital has more.
