Interpretation: Radiations that come from naturally occurring sources should be identified.

Concept Introduction: Radiations is all around us it may come from naturally occurring sources and human-made sources. They occur when a source emits energy and travels through a medium such as air and absorbed by matter. There are two types of radiations ionizing and non-ionizing.

Correct answer:

a. rocks and soil
b. radon
e. cosmic rays

Expert Solution & Answer

Explanation of Solution

Reason for correct options:

Rocks and soil emit radiation this is called terrestrial radiation and comes naturally from the earth.
Radon is a radioactive element coming from the decay of the uranium in rocks and soil.
Cosmic rays come from the outer space, this is a natural source. The outer surface of the earth is continuously bombarded by these radiations. It consists of fast moving particles present in the space. They are mostly protons.

Conclusion

Reasons for incorrect options:

Nuclear medicines are made in pharmaceutical factories thus, radiation produced from them comes under human-made radiations.
Similarly, the radiations produced by nuclear power plants are due to chemical reactions occurring in the plants for production of electricity. Thus, it is also a source of human-made radiation.

Conclusion:

Thus, correct options are (a), (b) and (e)
