To show how the radiation resistance of electronic equipment can be increased, a mission and traffic control subsystem was modified for radiation resistance and then tested. The subsystem contained the following: marker beacon receiver, uhf transceiver, radio receiving set, TACAN transceiver, air-to-ground identification set, radio beacon, and air-to-air identification system. The results are summarized for the following pieces of electronic equipment: transformers (power, audio, pulse), relays, and capacitors (Ta, Nb, film, mica). Materials to be avoided in construction of the above pieces are given. Cannon connectors and transistors were also radiation-tested. (D.L.C.) 16l25 The cation exchange resins, Dowex 50W-X12 and Duolite C-10, and the anion exchange resins, Dowex 1-X4, Dowex 1-X8, and Permutit SK, were irradiated up to a gamma dose of 2.7 x 10/sup 8/ rad and the resulting changes in their total ion exchange capacity, salt-splitting capacity, moisture content, and particle size were measured. The results indicate that Dowex 50W-X12 and Permutit SK are the most stable of the cation and anion exchange resins, respectively. The main source of radiation damage to cation exchange resins of the sulfonated polystyrene type is in breaking of cross-linkages, while quaternary amine anion resins suffer damage through degradation of functional groups.
