Management of Spent Sealed Radiation Sources

Abstract: Spent or disused sealed radiation sources--no longer needed sources--may represent a risk of radiological accident or may be a target for criminal acts in countries where final disposal options are unavailable and where an increasing number of sources are being kept in extended storage. In developing countries, thousands of radium needles, teletherapy sources, oil well logging neutron sources, and miscellaneous industrial radioactive gauges are annually collected as waste and stored in research institutes.

“…[An evaluation of a report (Vicente et al, 2004) on the sealed source inventory in Brazil (a country of ~186 million people) gives a (corrected) estimate of 7.13 x 10 +5 Ci ---using that ratio for the 23 million people in Taiwan, one estimates ~9,000 Ci from sealed sources alone.] It is not clear if the inventory of medical and industrial waste in the INER report represents all such waste in Taiwan, or for example, perhaps only represents a small fraction of orphan material which ends up in storage at INER, while the majority of the medical and industrial inventory remains in storage at the owning locations or is returned to the original manufacturer outside of Taiwan.…”

“…Após sua utilização, as fontes são denominadas fontes radioativas seladas descartadas (FRSD). As fontes que não podem mais ser utilizadas para sua finalidade primária e que não tenham previsão de utilização em nenhuma outra atividade se tornam, dessa forma, rejeitos radioativos (VICENTE, et al, 2004). O conjunto das atividades realizadas para garantir a destinação correta desses rejeitos é denominado gerência de rejeitos radioativos.…”

“…Alguns acidentes com fontes radioativas seladas (como o acidente em Goiânia, em 1987) resultaram em fatalidades e contaminação de grandes áreas urbanas e agrícolas (VICENTE et al, 2004). Além disso, os ataques terroristas em 11/09/2001 nos Estados Unidos da América deixaram algumas preocupações quanto a possíveis ataques terroristas usando as chamadas bombas sujas, fabricadas com alguns tipos de fontes (GRIMM, 2004;McFEE et al, 2006).…”
