It appears that nowadays we are exposed to more radiation than ever before. We rely heavily on electronic devices such as laptops, tablets, and smartphones and cannot imagine a day without them. Despite their common usage, these devices have a negative effect on our health. Even the various electric appliances we use at home on a daily basis are considered unsafe.
Now, let's delve into the matter further and differentiate between what is truly hazardous and what is not.

Home Electric Appliances
Household appliances like blenders and washing machines produce a magnetic field that can affect our bodies. However, the strength of these emissions varies depending on the type of appliance. Scientific studies suggest that vacuum cleaners and microwaves are among the most radiation-emitting household appliances. At a distance of 30 cm, they create alternating magnetic fields of 2-20 µT and 3-8 µT respectively. It is therefore not advisable to stand close to them while they are in operation. Electric shavers, hair dryers, and washing machines also emit radiation, although to a lesser extent. The radiation emissions from other electric appliances are hardly noticeable and pose little risk to our health.
Mobile Phones
There is ongoing debate about the potential harmful effects of mobile phones on the human body, specifically how they may impact brain activity and potentially lead to serious illnesses like cancer. While mobile phone manufacturers deny these claims, numerous studies have contradicted their arguments.
Mobile phones emit the highest level of radiation when the signal is weak or when you're making or receiving a call. The radiation emission is directly influenced by the signal strength. A phone with a good signal can emit a minimum level of radiation equal to 0, 01W, which is considered safe for usage. However, as the signal weakens, the radiation levels may increase up to 2W.
In situations where the signal is poor, such as in areas with weak network coverage or during high data usage, the radiation emitted by the phone can be higher. This is because the phone needs to work harder to establish and maintain a connection, resulting in increased radiation emission.
The Federal Communications Commission (FCC) sets acceptable radiation limits for mobile phones. The specific absorption rate (SAR) is the measure used to determine the rate at which the body absorbs the electromagnetic radiation. The FCC has set the maximum SAR limit at 1.6 watts per kilogram.
According to a report by Digital Information World, some smartphones have been identified as more dangerous in terms of radiation emission. However, it's important to note that the level of risk is still within acceptable limits set by regulatory bodies. It is recommended to follow safety guidelines provided by manufacturers and regulatory agencies to minimize exposure to radiation from mobile phones.
Here is the list of the latest smartphones with the highest radiation emissions:
| BRAND | PHONE MODEL | SAR VALUE |
|---|---|---|
| Motorola | Edge | 1.79 W/kg |
| Apple | iPhone 8 Plus | 1.59 W/kg |
| Pixel 6A | 1.59 W/kg | |
| Samsung | Galaxy S22 | 1.59 W/kg |
| Sony | Xperia XA2 Plus | 1.41 W/kg |
| Pixel 3 XL | 1.39 W/kg | |
| Pixel 4a | 1.37 W/kg | |
| Huawei | P Smart | 1.27 W/kg |
| OnePlus | 9 | 1.26 W/kg |
These are the phones known to emit the least radiation:
| BRAND | PHONE MODEL | SAR VALUE |
|---|---|---|
| Samsung | Galaxy Note 8 DUOS | 0.17 W/kg |
| Samsung | Galaxy Note10+ 5G | 0.19 W/kg |
| Samsung | Galaxy Note10 | 0.21 W/kg |
| Samsung | Galaxy A80 | 0.23 W/kg |
| LG | G7 ThinQ | 0.24 W/kg |
| Motorola | Razr 5G | 0.27 W/kg |
| Sony Mobile | Xperia 5 II | 0.28 W/kg |
| LG | V60 ThinQ 5G | 0.35 W/kg |
Mobile Phone Signal Booster
It is often believed that mobile phone boosters contribute significantly to increased radiation emissions as they are not widely used. However, research suggests that this concern may be overstated. The power emitted by a mobile repeater is 0.1W, which is similar to that of a regular cordless phone found in our homes. Additionally, the emitted power is shared among multiple antennas, which are positioned at a considerable distance from the user.
Positive Influence of Signal Booster to Radioactive Emissions from cell Phones
The two components of mobile communications are the base station and the cell phone.
When a mobile phone booster is used, it is also considered the "base" for the cell phone. When the device is turned on, as well as during a conversation, an electromagnetic background is created, which is absorbed by the human body. Scientists have proven that the level of radiation is directly related to the distance to the "base". In rural areas, where the signal quality leaves much to be desired, and there is no communication amplifier, the rates of diseases associated with EMR exposure are 2-3 times higher than those in urban areas.
If we check the maximum output power of a mobile signal booster, we will see a value from 10 to 200 mW. And our mobile phone has the maximum output power of up to 2000 mW!!! This is its maximum output power that it emits when it is in a room with poor signal reception in order to "reach" the operator's tower. This is the case when the battery runs out quickly! When the signal is good, the radiation is 100-200 mW. Accordingly, by installing a mobile amplifier with a power of only 100 mW, we reduce the radiation of our phone by 10-20 times.
The conclusion is more than just evident - the use of a signal amplifier where necessary reduces the harmful level of radiation. A mobile booster reduces the power of the phone from maximum to minimum, that is, it guarantees safety when using it.
