I completed a Masters thesis comparing radiation induced
polymerisation of monomers (MMA, HEMA) with PEG impregnation
followed by freeze drying which is available on interloan from the
University of Auckland Library.

    Waterlogged Wood Conservation: an investigation of radiation
    induced polymerisation of monomers. January 1985 (library no:
    85-176)

My results showed that even though results of using radiation
induced polymerisation of monomers (RPM) were satisfactory to good
the RPM technique not be considered a blanket replacement for the
established (and now very fine tuned) PEG impregnation/ freeze
drying treatment.
