The radiation sensitivities of crystalline choline chloride and nineteen crystalline analogs have been compared. The chloride is extremely radiation sensitive and appears to decompose by a free-radical chain mechanism. Choline bromide is about one-third as sensitive as the chloride; none of the other analogs show abnormal radiation instability. That choline chloride's susceptibility to radiation damage is a function of its crystal structure is shown by its contrasting stability in solution. Determinations were made of the radiation sensitivity of crystalline choline chloride at low temperature, in the presence of added iodide or iodine and after repeated recrystallizations. The electron spin resonance signal from irradiated choline chloride also was observed. (auth)
