Resumo
A team of CNEN experts successfully conducted an operation in Panama to recover and condition disused
radioactive sources stored in an unsafe condition. The sources, containing the Ra-226 isotope, were used in the
past to treat tumors using the technique known as brachytherapy and were immobilized in a complex package
buried in an old hospital wing destined for demolition. The compartment where the package stayed for decades,
built under the floor of a hospital laboratory, was contaminated with radon and daughters, including Pb-210,
responsible for the contamination found. The operation consisted of extracting the package from this
compartment, placing it in a cylindrical metal overpack, transporting it to the temporary storage site and carry
out site decontamination. Besides the package with the sources, three 200L drums containing contaminated
debris from the demolition of walls and floor were generated. No relevant event of radiological protection, such
as occupational dose above the established limits, contamination of personnel or place, etc, was observed. The
package produced, together with those containing the contaminated debris, was transferred to the facilities of the
National Oncology Institute.
