The iodine‐131 content of thyroid glands from Australian sheep and New Zealand sheep and cattle has been measured at weekly to monthly intervals from 1966 to 1972. In Australian sheep thyroid 131 I levels rose sharply from 2 to 4 weeks after the start of each series of Pacific bomb tests. Maximum levels were reached 6 to 18 weeks after tests commenced. The highest average levels reached ranged from 1,000 picocuries per gramme (pCi/gm) in 1966 to 65 pCi/gm in 1972. Values for New Zealand animals were similar to those found in Australian sheep. Radioactivity detected on several occasions between Pacific tests was probably due to Chinese atmospheric tests.
