Cellphones Versus Radiations

Cell phone use has become a daily habit for almost everyone in the world. They have evolved from the original use which was making and receiving calls to become a sort of obsession and some people, find it hard to put their phones down. However good they are and how they have transformed our lives, their use poses a threat for human health because there is a possibility of them being a cause of cancer and tumor development.cellphones-versus-radiations

Radio frequency energy waves get emitted from the cell phone antenna which can be absorbed by our bodies. These waves are believed to increase the risk of cancer development. There are numerous factors you should take in consideration when determining the harm that could be done by your phone such as how much time you talk on your phone, which type of phone you are using, the way you holding.

The Specific Absorption Rate:

The Federal Communications Commission in the US regulates the phones sold in the US  by determining their Specific Absorption Rate (SAR). According to Wikipedia, SAR is a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field; although, it can also refer to absorption of other forms of energy by tissue, including ultrasound. With regards to cellphones, the SAR value is the rate of radiation that gets absorbed in the human body when using a certain phone. The allowed value is up to 1.6 watts per kilogram (W/kg). Any phone that has a greater SAR value than the allowed is banned from sale.

SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass.

Protect Yourself from Radiations:

It is very difficult to protect yourself wholly from radiations emitted by cellphones. However, here are some tips you can use to help lower the radiation effect:

  • Talk on speakerphone;
  • Buy a radiation-protective case;
  • Turn it off as often as possible;
  • Use airplane mode more often;
  • Keep your phone away, especially from the bra area;
  • Check the SAR value of the cellphone you are about to buy.
