Smoke detectors to warn us of fire, x-ray machines to detect weapons or other devices in luggage and cargo, and certain types of imaging to look for diseases are all application of radiation for the benefit of society.
How can radioactivity be helpful and harmful?
Although it can be destructive, radioactivity can also be beneficial, especially when it comes to medical tests and certain medical treatments. Not only can radiation find tumors within the body, it can also destroy them or slow their growth.
What are the effects of radiation to humans?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
What is an important source of radiation?
Exposure from terrestrial radiation. The composition of the earth’s crust is a major source of natural radiation. The main contributors are natural deposits of uranium, potassium and thorium which, in the process of natural decay, release small amounts of ionizing radiation.

What are the pros of radiation?
It can stop or slow the growth of Cancer.
What are the uses of radioactivity in healthcare?

What are the risks of radiation?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
