What is Mobile Phone SAR value? How can I reduce mobile radiation?

Hello and welcome to my video blog. Today I'm going to talk about Specific Absorption Rate or SAR, which is a measure of how much electromagnetic energy from radiofrequency fields is absorbed by the human body. This is important because we use many devices that emit RF radiation, such as smartphones, tablets, and wireless routers. We want to make sure that our exposure to RF radiation is within safe limits set by regulatory authorities to protect our health.

SAR is expressed in units of watts per kilogram (W/kg) and represents the amount of RF energy absorbed per unit mass of body tissue. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has prescribed a maximum SAR value of 1.6 W/kg for mobile phones measured over 1 gram of tissue. Manufacturers are required to test their devices and provide information on the SAR values to users. SAR values vary depending on the specific device and its usage. They are usually measured at the highest power level that the device can emit, in the most unfavorable conditions (e.g., when held close to the body).

But what happens when the SAR value is high? Does it mean that we are at risk of damaging our body at a cellular level? Well, there is no conclusive evidence that high SAR values can cause adverse health effects. However, it's always better to be cautious and reduce our exposure to RF radiation as much as possible. Here are some steps that we can take to do that:

- Reduce the amount of time spent using your cell phone.

- Use speaker mode, headphones, or earbuds to place more distance between your head and the cell phone.

- Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power.

- Use airplane mode or flight mode when you don't need wireless connectivity. This stops the microwave radiation emissions from your device.

- Consider texting rather than talking - but don't text while you are driving.

- Don't sleep with your phone nearby. It may affect your sleep quality and expose you to unnecessary radiation.

I hope you learned something new today about SAR and how it affects our body. Thank you for watching and stay tuned for more
