The use of nuclear energy must be properly regulated to safeguard mankind and the environment. While nuclear technology offers significant applications, its weaponisation and testing have caused catastrophic historical destruction, severe environmental contamination, and lasting biological harm through radiation spread.
Radiation from nuclear tests damages the exposed individual and can also affect future generations.
Nuclear weapons utilise tremendous amounts of energy released from fission processes. When detonated, the immense thermal energy and shock waves cause immediate mass casualties, structural melting, and widespread radioactive fallout.
Early research on nuclear energy began in the 1940s to produce the atomic bomb. Plutonium, a byproduct of nuclear fission in nuclear reactors, was used to make the atomic bomb. J. Robert Oppenheimer is recognised as the "Father of the Atomic Bomb" after inventing it, though he later expressed regret after witnessing the explosion's devastation.
The atomic bomb "Little Boy" was dropped on Hiroshima on 6 August 1945. The atomic bomb "Fat Man" was dropped on Nagasaki on 9 August 1945. The nuclear explosion created a powerful shock wave that immediately killed approximately 70,000 civilians. The intense blast heat caused the entire city to heat up to the point that steel structures began to melt. Communication systems throughout the city were completely cut off. The surrounding environment was devastated by the shock wave and radioactive fallout.
The Nuclear Nonproliferation Treaty (NPT) is an international agreement established to control and prohibit countries from using nuclear weapons arbitrarily.
Nuclear tests are conducted to verify weapon function, but they contaminate the environment.
Nuclear tests are conducted to determine whether nuclear weapons function properly before they are deployed. Tests are carried out in the open atmosphere, on land, or underwater.
Radiation exposure impacts living organisms in two distinct ways: somatic effects and genetic effects.
Damage occurring directly to the exposed individual's body: tiredness, nausea, cataract, leukaemia, and hair loss.
Damage occurring to genetic material affecting future generations: deformation in babies, cell mutation, and cancer.
Answer in your mind, then press "Check Answer".
What was the primary purpose of early nuclear energy research conducted in the 1940s?
Why are nuclear tests conducted?
Give two examples of somatic effects and two examples of genetic effects caused by radiation.
All biological effects of radiation only show up in future generations.
Radiation causes both somatic effects, such as cataracts, hair loss and nausea, and genetic effects that cause deformities in offspring and cell mutations.
The Nuclear Nonproliferation Treaty (NPT) allows any nation to test and detonate nuclear weapons freely.
The NPT strictly controls and prohibits nations from manufacturing, acquiring, or using nuclear weapons arbitrarily.
1 Which atomic bomb was dropped on Hiroshima on 6 August 1945?
