Question 1

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 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: 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 5

True or false: A 2011 survey found that 40% of wild boar near Fukushima were radioactive, yet they still roamed towns.

Accepted Answer

True. Wild boar multiplied in evacuated zones, eating contaminated soil. Their meat showed high cesium levels, leading to culling programs.

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. Around 1,700 workers received doses above the 100 millisievert emergency limit, with a few exceeding 200 mSv, raising cancer risks.

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.
