radioactivity and radioactive decay on the development of radiotherapy and nuclear bombs

Question 1

What is radiotherapy?

Answer 1

The process of radiotherapy uses radiation, including high energy gamma radiation, to treat diseases such as cancer. Radiotherapy uses the radiation to destroy or injure cancer cells, preventing them from multiplying. It can be used to treat primary or advanced cancer.

Question 2

What is a nuclear bomb?

Answer 2

These weapons are explosive devices that obtain their destructive forces from nuclear reactions.

Question 3

What is the impact of nuclear bombs?

Answer 3

The blast produced a shockwave, massive amount of heat and ionising radiation, and had long term impacts on the surrounding environment. also can cause long term defects in humans. for example the event in hiroshima

Question 4

Define the differences of atomic and hydrogen bombs

Answer 4

Atomic bombs: These weapons release explosive energy as a result of nuclear fission reactions.

Hydrogen bombs: These weapons release a portion of their energy due to the process of nuclear fusion.

Question 5

Assess the impact of radioactivity

Answer 5

1. Radiotherapy can be very effective in treating cancer and destroying cancerous cells. It can be used to shrink tumours before surgery, destroy any remaining cancer cells after surgery, relieve tumour symptoms or be used as a treatment method when surgery is not a viable option.
2. can cause harm in growing populations if not used correctly.
