Contact readings on the container with a survey meter gave readings at background. Gamma spectrum analysis indicated U-235 activity at 18.3 pCi/gram. ADH Inventory Item #37 [UO2 in vial] has a mass of 12.6 grams, in appearance a cylindrical black item approximately 1 centimeter in length and 1 centimeter in diameter. Contact readings on the container with a survey meter gave beta readings of 3 mR/hr. and gamma readings of 0.15 mR/hr. Gamma spectrum analysis indicated U-235 activity at 4.05 E+3 pCi/gram. Analysis of all swipes taken in the location where the items were found and of the containers themselves show no evidence of contamination.
