What country was poisoned with radiation when the US tested the first hydrogen bomb there in 1952?

Answer 1

The contamination from the 1952 Ivy Mike test shot was limited to Eniwetok atoll, where the test occurred and the surrounding ocean where it had been predicted.

Perhaps you were thinking of the 1954 Castle Bravo test shot, which went way over predicted yield and contaminated a wide area in the Marshal Islands well beyond the predicted zone around Bikini atoll, where the test occurred. Rangarok island was heavily contaminated and had to be emergency evacuated for several months and the Japanese fishing boat Fortunate Dragon was contaminated.

Technically no country was poisoned by any of the US pacific testing, as the Marshal Islands are not a country but a US protectorate. Bikini atoll and Eniwetok atoll, where the tests occurred were contaminated bad enough that even now after cleanup they are not suitable for full time occupation. However this was not due to either Ivy Mike or Castle Bravo, but to the full history of testing there from the first 1946 Crossroads series to the last 1958 Hardtack II series.

The US testing that poisoned a country was the Nevada testing, fallout from these tests hit every one of the lower 48 states as well as parts of Canada and Mexico. However we still live here.

Answer 2

The island nation of the Marshall Islands was poisoned with radiation from the first hydrogen bomb test conducted by the US in 1952. The test took place at Bikini Atoll and resulted in extensive contamination and lasting health effects on the indigenous population.
