Radiolytic stability of a resorcinol-formaldehyde polycondensation-type cation exchange resin was investigated for up to lE09 rads total dose. The resorcinol-formaldehyde resin is a resin that has potential cesium decontamination applications at Pacific Northwest and Savannah River. We have determined both radiation and storage effects on performance of the resin using 101-AW Hanford simulant and ASTM Type-I water. Distribution coefficient determinations, total carbon analysis, and physical observations lead us to conclude that radiation up to lE08 rads does not significantly affect the performance of the resin. The resin is more stable to radiation in water than in 101-AW Hanford simulant. Also radiation or storage does not affect the thermal stability of the resin. Gas production rates for several resin slurries increased in the order of resin/101-AW Hanford simulant, resin/ASTM water, and resin/0.5 M HNO{sub 3}. H{sub 2} is produced from radiolysis of resin in 101-AW Hanford simulant with a G value of G(H{sub 2}) of 0.11 {plus_minus} 0.02 molecules/100eV and in 0.5 M HNO{sub 3} with a G value of G(H{sub 2}) of 0.27 {plus_minus} 0.02 molecules/lOOeV.
