The problem of “radiation” emitted by smartphones came back into the spotlight again, after France’s decision to ban sales of iPhone 12 phones, due to it exceeding the maximum limits of the electromagnetic waves emitted by it, after which Belgium announced that it was also investigating this issue.
According to the competent French authorities, the percentage of radiation issued by the iPhone 12 amounted to 5.74 watts per kilogram, while it was in the hand or pocket, which is higher than the European Union standard of 4 watts per kilogram, while Apple’s official website shows that the level of radiation issued by the iPhone 12 When it is near the head or body, it reaches a maximum of 1.17 watts per kilogram.
Communications engineer Issa Saad El-Din said in an interview with Sky News Arabia that the controversy has been going on for years about the dangers of radiation emitted by smartphones. Until now, scientists still disagree about the negative role that these radiations play in the human body, and the percentage of damage they cause.
Saad El-Din reveals that the disagreement among scientists regarding the dangers of radiation emanating from phones also reflects a major difference in the laws of countries that determine the percentage of dangerous radiation. There is no single percentage that unites countries, but rather each party determines the percentage that it deems appropriate based on His studies, pointing out that the laws specify two standards for measuring radiation, the first is related to the presence of the phone near the head and the second is related to its presence near the body.
Know the percentage of phone radiation
Saad El-Din explains that the phone emits electromagnetic radiation, which is measured scientifically, and it is known as the Specific Absorption Rate (SAR). Smartphone holders must browse the user manual for their phone to find out the percentage of radiation it emits, which is usually written after the phrase “ SAR”, or it can be found on the official website of the phone manufacturer, revealing that the lower the radiation rate is less than 1 watt per kilogram, the better. The user can also do a search on Google by writing the phone model accompanied by the phrase SAR.
Microwave waves enter the body of the phone holder
For his part, biomedical engineer Dr. Waseem Medlej said in an interview with Sky News Arabia that the smartphone is constantly sending electromagnetic waves in all directions, to search for the nearest transmission tower, as a high percentage of these microwave waves enter the body. The phone holder, so that his tissues can absorb them, stressing that the body’s absorption of radiation varies from one person to another. The older a person is, the less this absorption is, and vice versa.
Fatal mistakes… Apple warns iPhone users against these habits
Smartphone owners sometimes commit inappropriate actions against their phones, believing that these are normal actions, only to be shocked later that what they have done may have devastating repercussions.
This prompted Apple to issue a major warning to iPhone users about the potential dangers of some seemingly harmless habits, such as leaving the phone under the pillow while charging, noting that this behavior could lead to a fire or cause an electric shock.
In an interview with Sky News Arabia, the writer specializing in technology and artificial intelligence, Alan Al-Qarih, says that Apple has, over the past few days, updated the information contained within the “Important Security Information for iPhone” page on its website, in order to urge users to reconsider some of the “mistakes.” “deadly” actions they do, and asking them to be more careful in their daily behavior when dealing with the iPhone.
9 recommendations from Apple
According to Al-Qarih, the recommendations issued by Apple, which said that failure to adhere to them may lead to fire, electric shock, or damage, are as follows:
- Do not place the iPhone connected to the charger under the pillow while sleeping.
Do not place the iPhone under a cover or blanket while charging.
Do not sleep on the phone or charger while it is connected to power.
Do not charge the iPhone near damp or wet places.
Avoid contact of the charger with human skin when it is connected to power.
Stop using chargers if they are corroded or if excessive liquids are spilled on them.
Keep the front of the phone facing up when charging it.
Keep chargers in a well-ventilated area during use.
Avoid charging and using iPhone in a potentially explosive atmosphere, such as areas where the air contains high levels of flammable chemicals, vapors, or particles.
A common wrong habit
Al-Qarih explains that there is a common habit that many users do, which is leaving the phone under the pillow, or covering it while charging, and this habit is a fatal mistake, which all phone owners, not just the iPhone, need to stop doing, by placing the phone in places without proper ventilation. This leads to an increase in the temperature of the device, which increases the chances of a fire. He pointed out that Apple did not ask users to stop charging phones at night, but rather asked them not to place them in places where their temperature rises.
Danger of radio signals
Speaking to Sky News Arabia, Al-Qarih believes that what was striking about the warning was Apple’s announcement that although its chargers comply with international safety standards, this does not prevent the outbreak of a fire or an electric shock if users do not comply. Terms of use established by you.
He pointed out that the company confirmed that the chances of a fire outbreak increase if non-original chargers are used.
Al-Qarih stressed the need for users to keep their phones away from the sleeping bed, not only while they are connected to the charger, but in all cases, as sleeping next to the phone has serious health damage, due to the radio signals it emits when it sends and receives information from the surrounding cell towers.
4 phones and 2 watches.. “Apple” announces the launch of its latest products
Apple unveiled its latest products on Tuesday, launching 4 new phones in addition to two smart watches.
The products announced by the giant American company at its annual conference in California are “iPhone 15”, “iPhone 15 Plus”, “iPhone 15 Pro”, and “iPhone 15 Pro Max”, in addition to the “Apple Watch Series 9”, and the “iPhone 15 Pro” version. The second of the “Ultra” watches.
