- 10.Electromagnetic radiation is an insidious culprit. Once upon a time, the major concern around electromagnetic radiation was due to high tension wires which carry huge amounts of electricity to cities. Now, we even carry sources of this radiation with us as cell phones, laptops, tablets and other wireless devices. While the most acute exposures to harmful levels of electromagnetic radiation are immediately realized as burns, the health effects due to chronic or occupational exposure may not manifest effects for months or years. Which of the following can be the viable solution for electromagnetic radiation reduction?
- A.
By using electric and hybrid vehicles and public transportation systems.

- B.
To implement hardware protocols to minimize risks and reduce electromagnetic radiation production significantly.

- C.
By building wind turbines to harvest natural wind energy.

- D.
By implementing regulatory procedures for vehicle emissions.
