About this file

This document is an Inventory for Disposal listing radioactive and hazardous materials requiring disposition. The inventory contains nine line items of radioactive waste contaminated with Carbon-14 (C-14) and Chlorine-36 (Cl-36) isotopes, with activity levels ranging from 17 microcuries to 350 microcuries. The materials include glass vials containing Permafluor and Carbasorb solutions in 30-gallon drums (three items totaling 30.6-29.7 liters each with 17-50 µCi activity and 45-80 kg weight estimates), three 15-gallon drums of Permafluor and Carbasorb liquid waste with 50 µCi activity and 80 kg each, one 55-gallon drum of contaminated glassware, sink drain, gloves, and paper with 100 µCi activity and 15 kg estimate, one bottle of 5 mL benzene with 50 µCi C-14 activity and 1 kg estimate, one bottle of 5 grams zeolite granules with 350 µCi Cl-36 activity and 1 kg estimate, and one bottle containing less than 1 gram of imidacloprid insecticide with 100 µCi C-14 activity and 1 kg estimate.

The chemical composition information identifies the constituent materials by CAS number, including Permafluor (composed of 80-100% 1,2,4-trimethylbenzene, 10-20% 1-methoxy-2-propanol, and trace butylated hydroxytoluene), Carbasorb (3-methoxypropylamine), benzene, zeolite, and imidacloprid. Total estimated weight across all items is approximately 428 kilograms.
