Abstract
- The effective radiation dose of palladium under the assumption that it is contaminated with 107Pd (1 Bq/g) is estimated through four exposure pathways: the inhalation of airborne particles emitted from an automobile exhaust control catalyst, ingestion via food or drinking water, ingestion of palladium in saliva after release from a dental application, and inhalation exposure of dust in the work place. The highest dose (3.17 × 10−9 μSv/y) was estimated in adult workers manufacturing palladium products. Considering variations in parameters and possible exposure pathways, it is concluded that this is the critical group for determining the clearance level of 107Pd. The clearance level, which is defined as a 107Pd concentration providing less than 10 μSv/y in any exposure pathway, is calculated as 3.16 × 103 Bq/g.
