10 cm 3 air saturated Fricke dosimetry solution in a 1 cm diameter tube is irradiated for 10 min in a 6~ source of gamma rays. The optical density measured at 304 txm in a 1 cm light path at 30~ was 0.260 after the completion of irradiation and 0.003 before irradiation. (a) What is the total dose in gray absorbed by the solution? (b) If 10 cm 3 of methanol is irradiated in the same tube for the same 10min, what is the absorbed dose in gray. The Z/A for methanol is 0.562 and that for the Fricke dosimeter is 0.553. Explain any assumption you make to solve the problem.

Question
A 10 cm 3 air saturated Fricke dosimetry solution in a 1 cm diameter tube is irradiated for 10 min in a 6~ source of gamma rays. The optical density measured at 304 txm in a 1 cm light path at 30~ was 0.260 after the completion of irradiation and 0.003 before irradiation.
(a) What is the total dose in gray absorbed by the solution?
(b) If 10 cm 3 of methanol is irradiated in the same tube for the same 10min, what is the absorbed dose in gray. The Z/A for methanol is 0.562 and that for the Fricke dosimeter is 0.553. Explain any assumption you make to solve the problem.
