(2) Does the decay influence the maximum penetration thickness? Many thanks, Pengzhu                  Reply  Translate  Close   tj tj 07:11 Nov-14-2008 Re: Maximum penetration of Ir-192 in steel ----------- Start Original Message ----------- : Hi, : We are using Ir-192 to examine the casting quality of a steel part with maximum thickness 95.25mm: : (1) Is Ir-192 OK for this application? : (2) Does the decay influence the maximum penetration thickness? : Many thanks, : Pengzhu ------------ End Original Message ------------ This would be working at the upper practical limit of Ir192. The energy levels would remain the same with decay. However, with loss of activity comes increased shot time and at 3in. of steel it would be impractical for normal use. Better to use higher energy x-ray or cobalt60 gamma.                  Reply  Translate  Close   Juan Amado Engineering, Inspection Arco Industrial, S.A., Panama, Joined Nov 2001, 44 Juan Amado Engineering, Inspection Arco Industrial, S.A., Panama, Joined Nov 2001 44 09:53 Nov-14-2008 Re: Maximum penetration of Ir-192 in steel ----------- Start Original Message ----------- : : Hi, : : We are using Ir-192 to examine the casting quality of a steel part with maximum thickness 95.25mm: : : (1) Is Ir-192 OK for this application? : : (2) Does the decay influence the maximum penetration thickness? : : Many thanks, : : Pengzhu : This would be working at the upper practical limit of Ir192.

Hope this helps, regards, Juan Amado                  Reply  Translate  Close   Peter Alfers Peter Alfers 09:53 Nov-16-2008 Re: Maximum penetration of Ir-192 in steel you can use Ir 192 in conjunction with two Films how will exposure at once. Than you need the half time for your right density .For the interpretation use the films lying upon each other.                  Reply  Translate  Close   Product Spotlight CIVA 2017 UT Module StandEXTENDE CIVA NDE Simulation Software is the world leader of NDT Simulation.
