I just recieved an update email as follows:"We do not have source material and do not know when we will be able
to obtain any"
I believe radiography is about to have a problem in 75 days, which puts us right at the start of outage season.
I believe if Se75 will perform your work and your licensed for the same, it would probably be a real good idea to get in the q for them given their extend half life. While these companies will eventually catch up, it cannot help but run thin if there is anything more than a half life backlog.
