I am looking for the effects (mainly in the short term) that you would experience if you were to go on an EVA wearing an IVA suit. For example, I don't think that the IVA suits have any form of protection from radiation. Unlike most EVA suits that have reflective coating made from Mylar.
I am mainly looking for things you would experience on that EVA, not a couple of days-years after(if you survived), but anything is useful :)
