What is the best way to minimize the effects of radiation from cellphone use?

I understand that the further away the cellphone is from the body, the less exposure- but I was wondering if there is a difference between using the earplug %26amp; cable (that comes with the phone), or using a bluetooth. Is one option safer than the other? Which one most reduces the radiation exposure?What is the best way to minimize the effects of radiation from cellphone use?
only use for data, emergency calls and messages

Research by governments who want to sell the bandwidth to the operators says that there is no problem. Basically you are holding a microwave transmitter capable of quite a few watts close to the most sensitive part of your body. Would you put your head in a microwave oven and switch it on? No. Best to keep that antenna away. Research HAS shown that some cables can increase exposure due to things that are too complex to expain here. My advice: use Bluetooth as it is very low power and predictable.What is the best way to minimize the effects of radiation from cellphone use?
Yes, there is a difference between bluetooth earpiece vs cabled earpiece. Bluetooth ear piece is transmitting and receiving signals to your phone, therefore there is a radiation (very very small amount, the manual will tell you the amounts). Plus there is a battery running as well, which also produces heat and radiation. The cabled earpiece has non of those, it simply allows the voice to travel to your ear. Therefore cabled is the one with the least.
Research have shown that the radiation is almost non-existant, so it doesn't matter whether you are using earplug or cable, because even without using those you'd be safe.What is the best way to minimize the effects of radiation from cellphone use?
Best way? Don't use your cell phone like it's a lifeline.
