Subject: [TN] Gamma Radiation Effects on Assemblies?

DC Members:

I have designed a flex assembly that will be subject to gamma radiation (25-50 kGy) for sterilization purposes.  We need to know the effects of this radiation on the materials;  Active & passive comps, polyimid flex, solder & joints, etc...

Can anyone point me in the right direction where I might begin to find this information?  Is there an overall document and specification?  Would I need to contact the manufacturer of each P/N and request this information.  I have done flight boards in which each component had to be rad-hard, is this a similar situation?

Thanks in advance!

David Baldwin CID+
