  Significant 1.8 MeV emission from the Carina region has been detected by
COMPTEL. The emission is concentrated within 6 degrees or less near the Carina
nebula NGC 3372, one of the brightest HII regions known in our Galaxy. This
region contains a wealth of extreme young open clusters whose massive stars
possibly contributed to an enrichment of 26Al in the ISM within the last few
million years. The relation of these clusters and the peculiar object Eta
Carinae with the observed emission is discussed. The 26Al yield of the clusters
is estimated using current theoretical nucleosynthesis models.
