US Department of Energy Reports on November 10: NNSA and Brazilian Partners Removed a Cesium-137 Source From a Manaus Hospital, the Eighth International Removal in Three Years
Manaus, Brazil — The US Department of Energy said on November 10 that the National Nuclear Security Administration worked with Brazilian partners to successfully remove a cesium-137 source from a hospital in Manaus, Brazil. The department described the operation as eliminating a high-risk radioactive source.
The source and the operation
The department said the operation targeted a cesium-137 source previously used in a blood irradiator at the Amazonas Hematology and Hemotherapy Hospital Foundation, known as HEMOAM.
In September, a team from NNSA Y-12 National Security Complex worked alongside Brazilian partners to safely disassemble, package and transport the radiological materials, the department said. Following removal, the cesium-137 source was secured in a radioactive-material shipping container and transported out of Manaus.
Place in the programme
The department said the Brazil operation marks NNSA's eighth international radioactive-source removal in the last three years.
The release gave no activity figure for the source. The facts and figures in this report follow the department release dated November 10.
