KOMPUTER JADUL-, Smartphones are always in our hands, whether for communication, work, or entertainment. However, behind the convenience offered, there are several risks of radiation emitted by mobile phones.
Every smartphone definitely emits a certain amount of electromagnetic radiation, which can be measured by the Specific Absorption Rate (SAR). The SAR value indicates how much radio frequency energy is absorbed by the body when using the device.
Although until now there has been no strong evidence that cell phone radiation is harmful to health, we need to know which models have the highest and lowest emission levels as a preventive measure.
List of Smartphones with the Highest and Lowest Radiation
The use of smartphones is so intense, making many people start to worry about the possible long-term impacts of cell phone radiation. The Statista page states that the German Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) has a complete database of various cell phones, both old and new models, along with their radiation levels.
According to the US Federal Communications Commission (FCC), the Specific Absorption Rate (SAR) level, which measures how quickly the body absorbs energy from radio frequencies, has a maximum limit of 1.6 watts per kilogram. Based on the data, the cellphone with the highest radiation level is currently the Motorola Edge.
The previous year, the iPhone 7 and iPhone 8 were almost at the top of this list. However, Apple's latest cellphone has a lower radiation level, so it is not included in the top 10 list.
Most of the cellphones with the highest radiation levels are older models. Although there is no global standard that sets a safe level of cellphone radiation, the German environmental certification "Der Blaue Engel" (Blue Angel) is only given to cellphones with SAR values below 0.60 watts per kilogram.
Here is a list of smartphones with the highest radiation, reported from the Statista, Bankless Times, and Visual Capitalist pages.
1. Motorola Edge - 1.79 W/kg
2. ZTE Axon 11 5G - 1.59 W/kg
3. OnePlus 6T - 1.55 W/kg
4. Sony Xperia XA2 Plus - 1.41 W/kg
5. Google Pixel 3XL - 1.39 W/kg
6. Google Pixel 4a - 1.37 W/kg
7. Oppo Reno5 5G - 1.37 W/kg
8. Sony Xperia XZ1 Compact - 1.36 W/kg
9. Google Pixel 3 - 1.33 W/kg
10. OnePlus 6 - 1.33 W/kg.
Some brands like Google, Sony, Motorola, OnePlus, OPPO, and ZTE have older models that emit higher radiation. However, only the Motorola Edge has the highest radiation level with a SAR value of 1.79 W/kg, exceeding the limit set by the European Union.
For the other 9 smartphones from this top 10 list, the SAR numbers are still below the established safe limit, making them relatively safe for humans. On the other hand, the ZTE Blade V10 is the smartphone with the lowest radiation level, at only 0.13 W/kg.
Samsung is also included in the category of phones with low radiation levels. The Galaxy Note 10+ is the best model, emitting only 0.19 W/kg. Here are some phones with the lowest radiation emission levels:
1. ZTE Blade V10 - 0.13 W/kg
2. Samsung Galaxy Note 10+ - 0.19 W/kg.
Explanation of Smartphone Radiation
Smartphones and other mobile devices emit small amounts of radio frequency (RF) radiation. This radiation can be absorbed by parts of the body, both when the phone is in use and when it is near us.
On the Visual Capitalist page, it is explained that the level of cell phone radiation is influenced by various factors, namely, such as the age of the device, the model, and the strength of its transmitting antenna. In addition, the distance from the nearest cell tower also plays a role in determining how much radiation is emitted.
Just so you know, the level of cell phone radiation is measured using the Specific Absorption Rate (SAR), which is a unit that indicates the amount of electromagnetic energy absorbed by the body when using a device.
The European Union sets a safe limit for cell phone radiation of 2 watts per kilogram, which is measured based on 10 grams of body tissue that absorbs the most signals. SAR values are usually measured at two points: on the ear (when used for making calls) and on the body (when stored in a pocket).
The average person spends about 5-6 hours per day using a cell phone. Because cell phones emit little radiation, we are indirectly exposed to radiation for hours every day.
So that was some explanation about smartphone radiation and a list of the highest and lowest radiation. Hopefully it will increase your knowledge, yes!
