Resumen
The year 2017 marks 30 years since the radiological
accident in Goi??nia, Brazil, which resulted from the leakage of Cs-137
from a teletherapy equipment. The contaminated material collected
during the response to the accident was disposed of in Abadia de
Goi??s, about 20 km from Goi??nia. However, in the initial 15-day period
before the authorities were notified, contaminated paper bales and
scrap metal were sold and transported to material recycling facilities
in the State of S??o Paulo, one thousand kilometers away. These
materials were later collected in steel boxes and drums, and stored
in the intermediate waste storage facility of the Nuclear and Energy
Research Institute - IPEN, in S??o Paulo. The objective of this paper is
to describe the work performed to check the present condition of
the paper bales waste boxes, reassess the reported Cs-137 activities,
and evaluate possible treatment methods that can be applied to
reduce the volume of waste. Prospective waste treatment methods
are discussed.
