Leach Test of Six 192-Iridium Pellets Based on the IAEA 'Special Form' Test Procedures

摘要

The designation 'special form' may be applied to indispersible solid radioactive material if the material meets the requirements of the tests described in the International Atomic Energy Agency Regulations for the Safe Transport of Radioactive Type Materials. This report presents the procedures and results of a leach test performed as specified in the regulations on 6 'as received' active 192-iridium pellets. Mechanical tests were not carried out prior to or following the leach test. The activity of each of the first 6 water baths was found to be between 2.3 and 12.6 mu Ci, (8.5 x 10 exp 4 and 4.7 x 10 exp 5 Bq) and of the second 6, between 1.3 to 6.0 mu Ci, (4.8 x 10 exp 4 to 2.2 x 10 exp 5 Bq) thus exceeding the allowable limit.
