Triangulation method is a well developed technique for determination of depth of a discontinuity. However, with thin sections, it is limited in accuracy. If you need any more information about the method, pl. get in touch. : S.V.Swamy : : sir : : 1. i have read an equation that Linear absorption coefficient= log2/HVL. I think this is related to gamma sources.Similarly is there any relation exists with respect to x-ray energies? please give me answer. : : 2. Is there any research paper related to defect depth estimation in radiography ( here depth is third dimension of defect .anyway we can measure length and width of the defect) ------------ End Original Message ------------ Thank you sir, please send some useful data/ site addresses for academic interest.actually my interest resticted to 6mm max thickness of aluminum alloys regards. gowrishankar Follow Ups: Re: radiography Nandeesh 11:18 May-14-2008 (7) Re: radiography Gowri santhosh Palika 06:47 May-15-2008 (6) Re: radiography Nigel 08:26 May-15-2008 (5) Re: radiography DJ Kallhof 14:14 May-15-2008 (4) Re: radiography Nigel 17:19 May-16-2008 (3) Re: radiography Nigel 17:23 May-16-2008 (2) Re: radiography DJ Kallhof 21:14 May-16-2008 (1) Re: radiography tj 14:17 May-29-2008 (0) Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : : Dear Gowrishankar, : : I would like to respond to your second question.
