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.
