I couldn't find any paper.
I believe that generally, the actual damage is the same from all forms of ionizing radiation.
I think most of the differences come in the mechanism and location of dosages, energy of the dose, and shielding requirements for different things.
Alpha radiation, for example, can be stopped by a sheet of cardboard, but if the emitter (such as a plutonium particle) is imbedded inside the body, it can do a lot of damage.
High-energy neutrons have the ability to make other things radioactive, something other forms of radiation don't do. A can of soup buried in fallout is safe to eat, assuming you can manage to retrieve it and clean it off somehow.

The DARPA website had basically the same news release.
