Question:

How can Human Health be affected by: -Radio -Microwave -Infra Red -Visible Light -Ultra Violet -X-Rays -Gamma Rays

Author: go kys



Answer:

-Radio can simply just Transmit few the Body, no Absorption -Microwave can be somewhat Absorbed, making the Cells heat up -Infra Red and Visible Light are usually just Reflected or Absorbed by the Skin, having more Heating. IR can Burn the Skin -Ultra Violet is also Absorbed by the Skin, but due to its Higher Frequency, it can Give more Energy causing more Damage. Electrons can also be Knocked off making Ionising Radiation, which may result in Genetic Mutation and Cancer, so very Bad -X-Rays and Gamma Rays are also more Ionising, and therefore can Damage Cells even more. They can also Penetrate Deeper Tissues
