Dear Mr. George Kharashvili,

Thanks for your reply.

For this problem I am scoring energy deposited in region VOL for
different back scatter thickness. As this thickness increased, the
energy depositionin VOL should increase . My interest is to estimate
required backscetter thickness that will provide complete back scatter
for beta/electron . So beyond this thickness if we increase the
thickness, energy deposition will not increase but it will be
flat.Theoretical and experimental value differ for this increase in
energy deposition vs backscatter thickness.

Regards,
