About this file
This is a waste box inventory document for RFB 20-128 detailing radioactive material contents and specifications. The document catalogs four waste boxes containing various radioactive isotopes and contaminated materials requiring proper disposal or management. Soil Box 1 contains 81 pounds of material across four containers with a total activity of 9.0E+06 DPM and a contact dose rate of 130 R/hr, including isotopes such as U-natural, Ra-226, Ra-228, Am-241, Cs-137, Co-60, Pb-210, and Th-232. Alpha Box 1 holds multiple alpha-emitting isotopes totaling 9.3E+05 DPM, with uranyl nitrate evaporated on planchets comprising less than 7 grams total mass. Alpha Box 2 contains primarily uranium and plutonium isotopes with a total activity of 8.1E+03 DPM. Old AB Planchets Box includes legacy planchet materials with isotopes including U-natural, U-232, Am-241, Cs-137, Pu-239, and Tc-99, totaling 1.7E+05 DPM.
The inventory represents hazardous radioactive waste requiring specialized handling and disposal. The materials include both alpha and gamma-emitting isotopes with varying half-lives and specific activities. Background dose rates and contact dose measurements are documented for safety assessment purposes. The boxes contain mixed contaminated items including planchets, filter paper, radiation detection disks, soil samples, and metal components. No pricing, set-aside information, contract terms, or award details are provided in this technical inventory document.
