Radioactive materials - packagings - tests for contents leakage and radiation leakage, approved International Standard, 1976

This International Standard specifies methods for contents leakage and radiation leakage tests of prototypes of packages designed for transport of radioactive materials. For the contents leakage test, a description is given of the immersion tank required to perform the test, of the activity measuring instrument and of the test procedure. The radiation leakage test consists in a comparison of the measurement of radiation shielding efficiency performed before and after the physical and mechanical environmental tests. The measurement of radiation shielding efficiency may be performed by a radiographic or a radiometric method. Details of test equipment and procedure are described for both methods
