Why does the Sun have radiation?

Sun is a huge ball of mass of hydrogen. So huge that the weight of the outer layers is crushing the mass at the center. The pressure experienced by the matter at the center causes some hydrogen atoms to fuse, forming the next heavier element Helium. So outer layers is converting hydrogen into helium

Does a cell phone emit 1000 times more radiation when its battery is low?

Do mobile phones (cell phones) emit harmful radiation or electromagnetic fields?

One BIG YES, if the radiation levels are not within limits. In countries like Switzerland where the radiation levels are least, it doesn't matter if the tower is over your terrace. But in India, it does matter. Legally permissible level of

Do CFL lamps generate/emit UV radiation?

It is true that they do, but the limit is defined by a recent study in the UK.  No closer than one foot at one hour a day is what is described as the safe limit.  most lights are much further away than one foot.  http://www.fda.gov/Radiation-Emi...

If my phone is in flight mode, will it emit radiation?

No they don't.Why?Because when the phone is being switched off or put into airplane mode,it sends a  "switched off "signal to the nearest MSO (A co-ordinating office for transferring phone calls).Now,the MSO updates the status of your phone number as "switched off".So when anybody calls you, it first goes to the MSO

What radiation comes from cell phones?

Electromagnetic radiation. *GASP* Radio waves.

Do newer cellphones generally emit more radiation?

If by "radiation" you mean something harmful, then no, neither old ones or new ones emit any harmful radiation at all. Cell forms operate using microwave frequency radio. If your body absorbs some of this energy, it warms up ever so slightly. Microwaves cannot break chemical or nuclear bonds. As long as

Does a mobile emits bad radiation even in offline mode?

In Offline mode, the device does not communicate with the mobile tower. Hence it does not emit radiation. Therefore it is advised that whenever you are giving your smartphone to your kid for gaming, you need to put it in the airplane mode.Offline / Airplane mode reduces radiation exposure from mobiles to near 0

Mobile phone mast radiation reaches people at a tiny fraction of the power level that mobile phone users receive when holding a mobile phone to their ear and making a call. The antennas point out from the mast and direct the signal so

Do cell phones emit more radiation while low on battery? Why or why not?

Low battery and high cell phone radiation do not form a causal relationship as is often portrayed. Battery has nothing to do with RF radiations from the cell phone.However there is an inverse relationship. In a low network area, the cell phone has to emit

Nope. The phone, WiFi and Bluetooth use nothing more than radio waves. We use the same word

Does mobile phone emit radiation if I take out the sim and use it just to check only internet?

Assumption: You are using the WiFi for connecting online.Perhaps i could qualify the rationale by saying that regardless of which ever form your device communicates to external sources - WiFi, BT or NFC - there is always a transfer of Electro Magnetic radiation involved.Therefore, even if you dont have a SIM and you are

Why is cell phone radiation so feared, and is it really as dangerous as we think? It uses microwaves, which has less energy than even visible light.

INTRO: Today's cellular and Wi-Fi networks rely on microwaves – a type of electromagnetic radiation utilizing frequencies up to 6 gigahertz (GHz) in order to wireless transmit voice or data.5 G applications will require a new spectrum bands in higher frequency ranges above

When do cell phones emit the most radiation?

Cell phones operate in full duplex mode, which mean that they transmit and receive at the same time, on slightly different frequencies. So, anytime that the cell phone is making a call, it is transmitting for the entire duration of the call.

What is the radiation level in a mobile phone in standby mode vs speaking mode? Is the dual SIM mobile emitting higher radiation?

On a speaking mode, a cell phone is communicating with the tower multiple times over within unit time. In a standby mode, this communication with the tower is limited to basic minimum. Therefore in the speaking mode, your phone radiates more EMR/ RF radiation.2 is always higher than 1. No?
