ABS>G-yields of hydrocarbons resulting from /sup 60/Co gamma - irradiation of normal saturated C/sub 12/, C/sub 14/, C/sub 16/, C/sub 18/, C/sub 20/, and C /sub 30/ fatty (carboxylic) acids in the crystalline state (and of the C/sub 16/ and C/sub 18/ acids in the liquid state) have been determined. G/sub RH/ values obtained are in substantial agreement with G/sub CO//sub 2/ values recently reported for the same substances (excepting the C/sub 30/ homolog) by Jones and his observation that G/sub CO//sub 2/ (and hence G/sub RH/) is, in general, inversely related to chain length is confirmed. Contrary to earlier claim melissic acid (triacontanoic acid, the C/sub 30/ homolog) behaves normally in this regard. Departures from the inverse chain-length relationship are compatible with and may be rationalized by consideration of an additional inverse effect of the density of the irradiated material. (auth)
