Do iPhone 13, 14, and 15 emit dangerous radiation?
Have you ever wondered about the impact of smart phones on your health?
Are you afraid that these devices are a source of harmful radiation that may cause cancer or other diseases?
In this article, we will try to answer these questions for the latest phones from Apple, which are iPhone 13, 14, and 15.
What are radiations?
Radiations are energy that travels in the form of waves or particles. Radiations are divided into two main types: ionizing and non-ionizing.
Ionizing radiation
It is the one that has the ability to remove electrons from atoms or molecules, which leads to changing their chemical or biological properties.
Examples of ionizing radiation
They are X-rays, gamma rays, and ultraviolet rays. These radiations are considered dangerous because they may cause damage to cells and DNA, which increases the risk of cancer or mutations.
Non-ionizing radiation
It is the one that does not change the structure of the material that it passes through, but it may affect its temperature or movement.
Examples of non-ionizing radiation
They are sound waves, light waves, radio waves, and microwaves. These radiations are considered less dangerous than ionizing radiation, but they may cause some complications if they exceed a certain level.
SAR level
SAR is an abbreviation for Specific Absorption Rate, which is a measure of the amount of energy that a living body absorbs from a radiation source.
SAR is measured in units (W/kg), and it is used to estimate the thermal effect of radiation on tissues. The higher the SAR level, the higher the potential heating of the body.
The World Health Organization sets a maximum SAR level of 2 W/kg for a 10 kg body part, and 4 W/kg for a 1 kg body part. These limits are based on scientific studies that showed that these levels do not cause a noticeable increase in body temperature or change in its vital functions.
SAR level for iPhone phones
Apple publishes the SAR level for its phones on its official website, and confirms that these levels comply with international and local safety standards.
According to the available data, the SAR level for iPhone 13, 14, and 15 phones are as follows: -
iPhone 13: 0.99 W/kg (head), 0.99 W/kg (body) - iPhone 14: 0.99 W/kg (head), 0.99 W/kg (body) - iPhone 15: 1.14 W/kg (head), 1.14 W/kg (body)
We can notice that the SAR level for these phones falls within the permissible limits, and does not exceed 2 W/kg for any part of the body. But, it should be noted that these levels express the maximum value that the phone may reach in certain conditions, such as using a weak network or transferring a lot of data.
In normal cases, the SAR level may be much lower than these values.
Conclusion
It cannot be denied that smart phones emit some non-ionizing radiation that may affect body temperature or molecule movement in it.
But, it seems that this effect is very slight and does not pose a major health risk, especially if the user follows some precautionary measures, such as using earphones or a phone holder during calls, or avoiding placing the phone near a sensitive area of the body. Therefore, it can be said that iPhone 13, 14, and 15 phones do not contain radiations that affect humans negatively, provided that their use does not exceed reasonable and necessary limits.
