Smartphone Radiation for Health – You Should Know in 2020

Published by Amritangshu De on

Okay, So everyone reading this article is definitely using a smartphone, RIGHT?

Nowadays, Smartphone plays the role of a miniature computer with the features of a simple mobile phone.

According to Backlinko, People spend their time only on social media is  144 minutes each day.

With day to day rise in technological development and digitization of everything, it has become an essential part of our daily life.

Like everything, there’s a good and bad side.

With the rising use of smartphone from morning to night in our daily life, it’s radiation and their concerning effects is a havoc cause of anxiety for a lot of people.

As many of them don’t have a clear view of their smartphone radiation.

Here we describe scientifically the causes, effects and required precautions of using your smartphone positively and efficiently.

So, Let’s dive into this topic…

1. Waves: Where It Falls In The Chart?

➡ All of you have wondered someday or the other about the safety of the smartphone that you’re using, right?

Let’s see where the smartphone radiation waves fall in the electromagnetic spectrum if we present them according to their wavelengths.

So the radiowaves of smartphones we use falls after the visible light. That means they have greater wavelength than visible light and hence less frequency than that of visible light.

So it has way less energy than visible light as E=hf;

Where,

  • E= energy
  • h= constant
  • f= frequency

2. Smartphone Radiation

➡ So talking about smartphone radiation, that is variable. It depends upon the place you’re in, the signal of the operator you’re using, or, whether using Bluetooth, location, hotspot, or wi-fi.

You will be wonder, Most people keep their Voice Assistant in their Living Room that gives Radiation.

It is not good. 😥 

3. How Radiation Can Harm Us?

➡ Any kind of radiation has an adverse effect on health.

1. The ionizing radiations like X-ray, Gamma-ray can even change the DNA configuration and initiate mutation, even leading to cancer.

2. As the smartphone radiation falls in the range of non-ionizing radiation, it can’t form mutations. But non-ionizing radiation can produce enough heat.

That’s the principle of today’s microwave cooking machines.

In the same way, at the cellular level, it can produce heat and damage a cell. But talking about evidence, in the past years no chronic disease curve had gone the same way following the graph of increasing smartphone use.

4. What Is The SAR Value?

➡ SAR value is the Specific Absorption Rate value that tells us about the radiation levels of a smartphone we’re using. Its units are W/kg per 1g or 10g of body tissue (variable across countries).

5. Standard SAR Values Of Some Countries

➡ Basically, there are roughly 2 ways in which SAR values are measured. India and some countries including the US follow a method in which the SAR value is capped at 1.6W/kg per 1g body tissue.

Others including the UK follow a limit 2.0W/kg per 10g of body tissue.

Basically, These two methods are different in measuring procedures and can’t be compared numerically. It doesn’t mean anyone between these two methods accepts more radiation than others.

6. How SAR Value Is Measured?

Well,

The SAR value isn’t measured directly on human subjects. It’s measured on a dummy model filled with a special liquid that resembles the EM wave absorption characteristics of the human body tissue.

It’s measured in different positions and postures, like keeping the phone on-ear (head SAR), in the pant pocket, in the chest pocket, etc.

Look at this.

You can use this Formula to measure the SAR Value.

7. Importance Of SAR Value

➡ In India, the max SAR limit is 1.6W/kg. Every phone sold in the market has different SAR values: one for head called Head SAR, one for other body parts (Body SAR), SAR with Bluetooth on, SAR with the hotspot on.

Every one among these has to be under the said limit, 1.6W/kg. Among these, head SAR and body SAR are mandatory to be listed on the retail box of the product.

The SAR value isn’t the absolute value of radiation. It’s the limit in the worst possible condition. A phone having 1.4W/kg SAR value doesn’t necessarily emit 1.4W/kg all the time.

In the worst possible condition, it can touch that value. The real-time radiation is lower than the SAR value of the product.

8. How You Can Check The SAR Value Of Your Phone?

➡ In Google and Youtube, Most demand Query is “How can I check my phone radiation level?

Look at this,

Just Simply dial *#07# on your phone and you’ll get it.

Like this,

It’s also mention in the retail box that will help you before you buy it.

9. Conditions When Smartphone Radiation Increases

➡ Radiation increases in the place where the signal strength of the operator is low and in moving vehicles where the network strength changes rapidly. It increases when Bluetooth, hotspots are turned on.

10. SAR Values Of Commonly Used Smartphone Brands In India

Every smartphone sold in the Indian market has to go through long procedures of certifications under BIS (Bureau of Indian Standards). Then only the product can be launched and sold for people.

In India, the TEC (Telecommunication Engineering Center) set the limit of SAR Value.

11. What Precautions Should We Take To Minimize Smartphone Radiation?

➡ Minimize using smartphones in moving vehicles as the network fluctuates very quickly.

Use least at places with low network strength.

Avoid using Bluetooth headsets/earphones and use wired earphones.

Conclusion by Author

We hope you enjoyed this Duo research of Amritangshu De & Puspendu Khan.

In Conclusion, the SAR value is just a capping of smartphone radiation under the limit so that in no circumstances it crosses the safe value though there’s not a value we can take as absolutely safe.

And the SAR doesn’t mean the real-time radiation of smartphones. That’s always under the SAR only.
