Samsung M21S SAR value is the measure of the rate at which electromagnetic radiation energy emitted from the Samsung Galaxy M21S handset and the base station or mobile tower. All SAR (Specific Absorption Rate) values are expressed in units of watts per kilogram (w/kg). In our daily lives, we have to use various electronic products that produce electromagnetic radiation, and our body’s soft tissue is exposed to this radiofrequency energy.
On the other hand, every human or animal body can absorb a specific amount of energy. However, there is a limit of how much RF a human body can absorb, and when the RF level is higher than the absorption capacity of soft tissue, it will affect and damage the tissue slowly. The more time you are talking over the phone, the more heats it will emit, and your body has to absorb this energy.
The smartphone is one of the gadgets that emit electromagnetic radiation, and we, the humans, have to absorb this energy. Samsung Galaxy M21S also produces RF, and to be on the safe side, we must know how much energy it emits so we can stay safe.
In this post, we will look into the Samsung M21S SAR value—head SAR and body SAR. Besides, you will find the SAR value compared to the SAR value of other Samsung smartphones.
Introducing the Samsung Galaxy M21S
Released in November 2020, Samsung M21S packed with super features including a 6.4-inches display, fingerprint sensor, along with 6.27 x 2.96 x 0.35 inches dimensions. The weight is 191 grams. The device is powered by premium the Exynos 9611 (10nm) chipset with Octa-core CPU and you will find Android 10 OS.
Besides, you will get 4 GB and 6 GB RAM along with the 64 GB and 128 GB internal storage options respectively. Also, the Samsung Galaxy M21S smartphone comes with 64 MP, 8 MP, and 5 MP rear, along with 32 MP front cameras. With the fast charging option, you will get a non-removable Li-Po 6000 mAh battery.
Samsung M21S SAR Value Measurement
Galaxy M21S SAR value is me+asured in two ways; head SAR and body SAR. The head SAR value measures the amount of RF you head absorbs when you are talking over the phone, and the Samsung M21S device is close to your head. On the other hand, the body SAR value expressed the amount of energy your body has to absorb while you are keeping the Galaxy M21S smartphone anywhere near your body.
What is the SAR Value of Samsung M21S?
- Head SAR: N/A W/KG (USA)
- Body SAR: N/A W/KG (USA)
- Head SAR: 0.492 W/kg (EU)
- Body SAR: 1.13 W/kg (EU)
Samsung M21S SAR Value India
The SAR value of Samsung Galaxy M21S in India is 0.383 W/kg (head SAR), which is way below the government’s recommended limit that is 1.6 W/Kg. However, the maximum SAR value is recorded for the latest Galaxy M21S devices released in India.
Standard SAR Value
To operate properly within the wireless GSM network, all GSM devices have integrated transmitter and receiver for intercepting radiofrequency. The OEMs manufacturer the transceiver in such a way that the device will not exceed the limit for exposure to RF energy recommended by the regulatory board while using the handset next to the head and body. The RF exposure for smartphones expressed as a unit of measurement called Specific Absorption Rate (SAR). Here are the top three SAR authorities and their recommended SAR value limits.
- The FCC limit is 1.6 W/KG measured in a volume of 1g of tissue.
- The EU limit is 2 W/kg averaged over 10 grams of tissue.
- The Indian Government has set the new SAR limits to 1.6 watts per kg.
The above SAR limits set the regulatory authorities are part of the inclusive guidelines that establish certified levels of electromagnetic radiation for the general people. Also, with a systematic and complete assessment of scientific studies, independent scientific institutions have developed these standards for government and population.
What is Samsung Galaxy M21S SAR, why it should matter to you?
When you talk on the Samsung Galaxy M21S smartphone, your body is exposed to a certain amount of electromagnetic radiation. This radiation is produced by the transmission of signals between Galaxy M21S and the mobile base station. Here, the SAR shows how much of the radiation created by the device is absorbed by our body, more specifically, human tissue.
Typically, the lower SAR is better for us, and the higher SAR affects our body negatively. So if you know Samsung M21S SAR value, then you will understand it will be safe to use this smartphone or not. That is why in the above section, we have revealed the Samsung M21S SAR value.
In the USA, the FCC is responsible, authorized to control, and monitor the SAR value of all handset models distributed by mobile manufacturers. It has set the maximum SAR value is 1.6 watts per kilogram of bodyweight.
On the other hand, in European countries, the EU, the regulatory board has set the maximum mobile SAR value is 2.0 watts per kilogram.
However, in India, the maximum RF level is 1.6 watts per kilogram, which is similar to the USA standard.
Knowing the SAR value of the smartphone has tremendous health benefits for you. The higher SAR, which has exceeded your country’s standard, is known to harm the human. However, nowadays, maximum smartphone manufacturers produce mobile phones keeping in mind about the SAR; we recommend doing your study for your health and safety.
So when you decide to buy a new phone, at first, find out the SAR value of that device. If the SAR value is higher than the standard, then avoid it no matter how attractive the method is. On the other hand, if you figure out the SAR value of your chosen mobile is below the standard, then go for it.
Is Samsung M21S Safe to Use?
From the SAR perspective and the above data, we can see that both the head and body SAR value of Samsung M21S are significantly lower than the USA and EU SAR maximum standard. So we can say that it is safe to use.
How to Lower the Exposure to Samsung M21S Radiation?
If you have read the above sections, you have already known the Samsung M21S SAR value from the USA and EU standards. It seemed that the SAR value of this device is lower than both standards. However, the lower radiation does not mean that your body is not exposed to electromagnetic power. No matter which method you are using, your body is still absorbing the radiation; your device is emitted. To lower the RF even further, we have researched and found out a few tips for you. If you can follow these steps, you can reduce the radiation significantly.
- Different smartphones emit an unusual amount of radiation. So the first thing you should do before buying a new phone is to check the SAR value of the device. Moreover, we always recommend purchasing the mobile with a lower SAR value.
- People usually talk on the phone by keeping the device nearer the head; often, the tool touches the head; however, it seems many people press the cellphone against the head to hear the more precise sound when they are in crowded areas. Also, many individuals talk on the phone for a long time while the device touches the head. These practices are a potential health hazard, and these will increase the RF level; the more you talk, the more heat your body has to absorb.
So while talking on the phone, use headphones, speakerphone, or earpiece to reduce the proximity to the head. However, these wired and wireless sound devices may create some RF energy to the administrator. Still, these earpieces eliminate the higher source of electromagnetic radiation—your cell phone—from closeness to your head and thus can lessen the RF exposure to the head significantly.
- Do not talk a long time in one call. After a long time during the call, disconnect the line if you feel the device is heating up.
- Try chatting/texting instead of talking, if possible. Of course, do not text while driving.
- Always keep the Samsung M21S mobile away from your body and put them in a handbag, purse, or laptop bag.
- Avoid putting the Samsung Galaxy M21S smartphone in your pocket if the device is pressed up against your body.
- Try to increase the distance from the Galaxy M21S device to your body and head.
Elaboration and Terminology
