What was the fissionable material used in bomb dropped at Nagasaki (Japan) in the year 1945?
Text Solution
Verified by ExpertsThe correct answer is:
D
The bomb dropped on Nagasaki was known as 'Fat Man' and used plutonium-239 as its fissionable material. The choice of plutonium was due to its ability to sustain a rapid chain reaction necessary for a nuclear explosion.
Plutonium-239 is produced in nuclear reactors from uranium-238 and was less common than uranium-235, which was used in the bomb dropped on Hiroshima. Therefore, the correct answer is D.
