How does cell phones cause radiation?

Cell phones are small radios, that both transmit and receive. When they transmit they emit radio waves, which is a kind of radiation.


Antenna Boosters Increase the Surface for Cell Phone Reception?

Cell phone antenna boosters work much like satellite dishes by helping to capture and emit stronger signals. This, in theory, means stronger and clearer reception. The quality of the boosting antenna, however, is often related to the price of the device. As a passive device, the antenna booster is placed behind the phone's fixed antenna or on the rear surface. Booster antennas provide larger surfaces for cell phones to receive signals from transmitting towers.


Do radar towers give off any radiation?

Radar towers emit non-ionizing radiation in the form of radio waves. This radiation is considered to be safe for humans in normal levels of exposure but can potentially be harmful at very high levels or with prolonged exposure. Regulations and safety measures are in place to ensure that radar towers do not pose a health risk to the public.


What happens to people after a solar flare?

Very little happens to people after a solar flare. Solar flares are a regular occurrence. The charged particles they emit can disrupt radio signals and also increase the auroras.


Do mobile phones emit radiation only when receiving calls and SMS?

No. Cell phones may emit cellular radiation even when "idle". Smartphones may also emit radio signals for near-field, Wi-Fi, bluetooth, Ant, etc. Details: They emit radiation (a digital microwave signal) when they are first turned on, then continue to "check in" with a cell hub (or cell hubs if you are moving) so you are constantly connected to a cell hub. Your phone is "always ready" to receive incoming traffic because it is being "tracked" by your cellular service provider so that the nearest hub can relay your calls. If you are stationary, a single hub probably does this. But if you are mobile, cell hubs "hand you off" as you move, and all based on your phone's "checking in" signals to the hub.


What do stars emit besides heat and light?

They emit: gamma rays, radio waves, and x-rays. Some stars emit T.V. rays


How does a radio telescope see objects which are too dim for an ordinary telescope?

Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.


Do radio stations produce sounds?

No they emit radio waves. You need a radio receiver to turn what the station produces into sound.
