Question

Differentiate between the Following:

Sun radiation and Nuclear radiation

Answer 1

Basis of Difference	Sun radiation	Nuclear radiation
Source	Sun radiation comes from the Sun and reaches Earth as electromagnetic energy.	Nuclear radiation is emitted by unstable atomic nuclei during radioactive decay.
Common forms	It includes visible light, infrared radiation and ultraviolet radiation.	It includes ionising emissions such as alpha particles, beta particles and gamma rays.
Occurrence	Sun radiation is a natural source of energy and is received continuously by Earth.	Nuclear radiation may come from radioactive materials, nuclear accidents or radioactive fallout.
Effects	Excess exposure to ultraviolet radiation can damage skin and eyes.	Exposure to high levels can damage cells, cause illness such as cancer, and produce genetic effects.
