Have you ever noticed when the screen heats up when you're on the phone talking to someone for a long time? That's partially because of the cellular or Wi-Fi radiation.

But to grasp this, we must first describe electromagnetic radiation.

What is electromagnetic radiation?

The first few things that come to mind when you bring up the word "radiation" are generally x-rays, gamma rays, or NUCLEAR EXPLOSIONS! Not all radiation is toxic.

Electromagnetic radiation is pure energy, composed of electrical and magnetic waves traveling across vacuum.

Ionizing Radiation

Ionizing radiation produces high-energy, necessary to detach an electron from a molecule, which can destroy cell DNA. Types include x-rays and gamma-rays. Through proper use, can induce cancer or other adverse effects. Therefore, hospitals need patients to wear lead-lined, x-ray jackets or skirts for more safety

Non-Ionizing Radiation

Whereas, the most common type we see is non-ionizing radiation. This includes enough low-energy radiation that inflict damage to your body. In laptops, TVs, microwaves, other visible light, bananas (yes, bananas), and our skin, this type of electromagnetic radiation is commonly found.

Because radiation is invisible, you can not see them, but we tend to think of them as positive and negative magnets that react when the radiation passes, making them heat-up. That's how microwaves fry the coffee, and why your cell heats up when you're on a long-term call or exposed to sunlight. You shouldn't think too much, however, because you don't get a heavy dose of ionizing radiation.

According to Statista.com, there is no general standard for a "clean" amount of handset radiation, but the German eco-friendly classification ' Die Blaue Engel ' (Blue Angel) only certifies phones with a limited absorption rate of less than 0.60 watts per kilogram.

We think it's worth noting that 0.60 watts per kilogram is NOT a worldwide standard, so many smartphones often surpass this. Global Research has reported the top mobile lists that produce most and least radiation as of early 2019.

But this doesn't mean that smartphones are dangerous. Back in 2014 Cnet said in an article that its maximum Specific Absorption Rate, or SAR level, must be less than 1.6 watts per kilogram to pass the Federal Communications Commission certification and be sold in the U.S. But again, 1.6 watts per kilogram isn't a universal standard, so some firms still surpass it. Indeed, our devices utilize microwave radiation. Yes, the kind of microwave you see in. And you're not causing skin damage because you put your hand in the oven while running. And unless you're subjected to huge radiation, which is unlikely to happen, you're free.

And to keep you more at ease, your smartphone uses a lesser frequency at around 1.9GHz compared to your microwave’s frequency at 2.45GHz.
Nonetheless, if you still want to be cautious, here are some things that you can do:
  1. Avoid using your phone under direct sunlight for prolonged periods.
  2. Reduce your screen time.
  3. Don’t put your phone too close to your face.
  4. Use earphones or turn on speakerphones when taking and making calls.
  5. Switch to airplane mode or turn off your smartphone when not needed.
  6. And lastly, try not to hold onto your phone all the time. You can put it in your bag or a small pouch when you are out and about.
