The gamma-ray lines of 60Fe have now ben detected by two satellites. The first detection by Smith (2004) uses RHESSI, and the confirmation detection by Wang et al (2007) uses INTEGRAL. Both observations yield an 26Al/60Fe flux ratio of 0.17 ± 0.05. This agrees very well with predictions made in 1995 that the 26Al/60Fe flux ratio would be 0.16 ± 0.12.

Here is a recent talk on 26Al and 60Fe, and a review article on gamma-ray emmission from radioactive isotopes.

Visit Roland Diehl web site; he's always got the latest and best stuff on &gamma-rays from radioactive isotopes.
