How much radiation does a phone emit?

Cell phones emit radiation in the radiofrequency region of the electromagnetic spectrum. Second-, third-, and fourth-generation cell phones (2G, 3G, 4G) emit radiofrequency in the frequency range of 0.7–2.7 GHz. Fifth-generation (5G) cell phones are anticipated to use the frequency spectrum up to 80 GHz.

Where on earth is radiation the weakest?

Earth's magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. The magnetic shield diverts most of the radiation around the earth. Earth's atmosphere shields us from most of the remaining radiation that travels to Earth.

Where is the least radiation on Earth?

On an average those would be the poles. As you correctly pointed out, due to the tilt of the Earth's axis, there are large areas that receive very little and sometimes no sunlight at all and those change throughout the year. But on an average, poles are the ones that get the least amount of solar radiation.

Why are UV rays so strong in Australia?

Australia is near the equator so we experience high UV levels. time of year: our elliptical orbit around the sun and our axial tilt combine to ensure that we are closer to the sun in our summer than the northern hemisphere e.g. in summer the UK has UV Index 6–8, while Australia has UV Index 10–14.
