Question 1

True or false: The Fukushima disaster was triggered solely by the earthquake, not the tsunami.

Accepted Answer

False. The earthquake disabled external power, but the tsunami flooded backup generators, causing the meltdowns. Both were needed for the catastrophe.

Question 2

True or false: Radioactive water from Fukushima was dumped directly into the Pacific Ocean without any treatment.

Accepted Answer

False. Treated water (filtered of most isotopes except tritium) was released gradually starting in 2023, after IAEA approval.

Question 3

True or false: The Fukushima plant was designed to withstand a 15-meter tsunami.

Accepted Answer

False. It was built to handle a 5.7-meter tsunami. The actual wave reached over 14 meters, overwhelming defenses.

Question 4

True or false: Three reactor cores melted down at Fukushima Daiichi, not just one.

Accepted Answer

True. Units 1, 2, and 3 all experienced full meltdowns. Unit 4 had a hydrogen explosion but no core damage.

Question 5

True or false: After the Fukushima nuclear disaster, wild boar in the evacuation zone were found to have high levels of radioactive cesium, and they roamed abandoned towns.

Accepted Answer

True. Following the 2011 disaster, wild boar multiplied in evacuated areas, consuming contaminated food. Many tested for high cesium levels, leading to culling programs, and they were frequently seen in deserted towns.

Question 6

True or false: No deaths have been directly attributed to radiation exposure from the Fukushima disaster.

Accepted Answer

True. Official reports list zero acute radiation deaths. Evacuation-related stress caused some fatalities, but radiation itself killed none directly.

Question 7

True or false: Some cleanup workers at Fukushima have exceeded lifetime radiation exposure limits.

Accepted Answer

True. After the 2011 nuclear accident, over 1,700 workers received doses above 100 mSv, the typical career limit. Some exceeded 200 mSv, well above standard occupational limits, raising their long-term cancer risk.

Question 8

True or false: The Fukushima disaster led to a global phase-out of all boiling water reactors.

Accepted Answer

False. Many countries continued using BWRs with safety upgrades. Only Japan and Germany significantly shifted away from nuclear power.
