Question

If cell phones indeed cause brain tumors, will using hand free devices be enough?

Answer 1

I will be writing my opinion.

Since there is no known cause that says that cell phone's radio-frequency waves causes the brain damage. Because they are non ionising in nature. If there is also it is very small. To reduce this we can use
* Decreasing of amount spent on cell phones.
* Speaking on loud speaker or a head set to maintain a distance from the cell phone.

In this scenario if brain tumor growth is caused handsfree kits can play major role.

Hand free kits :
They have Bluetooth , audio and various type which is easy to wear.
These can be used to reduce the absorption of radiation from the cell phone. This is due to reason that they are held away from the body.
Since as we know there is no known risk from these radio-frequency wave exposure there is no reason to believe that hand free kits also reduce risks. They can be used for convenience sake.
If there is the risk of causing they definitely will be in help.
And authorities should take action to reduce the exposure caused from these waves.

Thank you...
