Facilities handling large amounts of α-emitters viz., isotopes of Pu and other actinides, make use of containment systems viz., Glove Boxes with leak tightness that have very low leak rates. During normal operations, the internal hazard to the lab personnel is practically negligible. However, some operations/events in the glove boxes may lead to loss of integrity of the containment. This could result in release of airborne α - activity inside the glove box into the working environment. Depending on the release of α - activity, the internal hazard may be significant. The assessment of intake and the estimate of CED in suspected cases are carried out. The paper describes the assessment of lab air activity, personnel contamination, intake and internal exposure during an event in glove box that had resulted in release of α-activity. The intake of the S - Class of Pu compound was followed up and the administration of chelating agent to the person was found to have resulted in the reduction of CED to the individual. |
