Likely so. It was in common use back then (and likely would be now if it was 
available), a really excellent glass formulation for what it offered. The early 
Minolta Rokkor 58/1.2 also had some lanthanum type glass, as did some of the 
Kodak 178mm aero ektars. So far, all are clearable with UV light, in my 
experience. 

Radiation risk from these is low in all cases.

    Thanks for the info. Was this glass in early 1.4/50mm's too? The
    silvernosed ones look yellow sometimes as well?
