Material selection

Glass

Glass is pretty good. When tempered and treated it's pretty shock-resistant, can handle a wide range of temperatures, handles radiation.

= Toughening = Tempering glass makes it strong. I've done this already on the leaf-in-glass project. Also soaking in molten potassium nitrate at 300 degrees for a while. This patent describes a process which uses all kinds of nasties dissolved in the liquid KNO3. I'm not going to risk fluoride poisoning.

Shielding

Some of the cooler options for electronics inside the sphere require microcontrollers and flash storage, which would have their effective lives extended with some radiation shielding. I'll use a leaded potting compound (if it exists), or lead sheets wrapped around the electronics.
