Which energy is released from the antennas of mobile towers and mobile handsets?
Question

Which energy is released from the antennas of mobile towers and mobile handsets?

A.

Magnetic field radiation

B.

Electromagnetic field radiation

C.

Ionising field radiation

D.

Extreme field radiation

Correct option is B

The correct answer is (b) Electromagnetic field radiation
Explanation
Mobile towers and mobile phones emit electromagnetic field (EMF) radiation, specifically in the radiofrequency (RF) range. This radiation is non-ionizing, meaning it does not have enough energy to break chemical bonds or damage DNA.
Additional information (other options)
· Magnetic field radiation: Only magnetic component—mobile towers emit combined electric + magnetic = electromagnetic waves, not pure magnetic radiation.
· Ionising field radiation: High-energy radiation (like X-rays, gamma rays) — not emitted by mobile phones.
· Extreme field radiation: No such scientific category.
Information Booster
· Mobile communication typically uses frequencies in the 800 MHz to 2600 MHz range.
· WHO and ICNIRP guidelines classify mobile tower radiation as non-ionizing and generally safe within prescribed limits.
· SAR (Specific Absorption Rate) is used to measure how much RF energy the body absorbs from mobile phones.
