CHEMICAL DOSIMETRIC EFFECTS MEASURED IN SOLUTION AND GEL
S>A study of the irradiation of two chemical systeras in aqueous solution and in agar gel revealed enhanced decomposition yields in the agar gels. The first system, consisting of agar: I/sup -/: I/sub 2/ indicator, exhibited a proportionate rise in I/sub 2/ yield with increasing agar concertration up to 0.3% agar, after which no further rise was observed. The enhanced value at this point was approximately 50%. The second system, consisting of agar: trichloroethylene showed a proportionate rise in H/sup +/ yield with increasing agar concentration up to 0.5% agar, where no further rise was observed. The maximum enhanced value achieved was about 200%. In the trichloroethylene system and presence of an acid dye indicator, bromcresol purple, had a depressive effect in solution and an enhanced effect in the gel. An increase in dye concentration in the gel extended the linear response of the system up to doses of 6.5 x 10/sup 16/ ev/g. (auth)
