The level of radio and electromagnetic waves that smartphones need in order to stay connected to a mobile network in order to receive calls and messages causes them to emit a certain amount of daily radioactivity.
A new study conducted by the Federal Office for Radiation Protection has published a list that reveals the 15 cell phones that emit the highest amounts of radiation.
For the most part, Chinese devices are the ones which emit the highest radioactivity, with 12 different models from Xiaomi, Huawei, OnePlus and ZTE companies being the biggest culprits on the list.
Apple is also in the ranking with its iPhone 7 and 8 models.
Before launching their devices to the market, technology companies must ensure that the level of radiation they emit is below the permitted limit to ensure they do not threaten the consumer’s health.
The National Cancer Institute of the United States has already conducted several studies that have examined the possible effects of this “non-ionizing” radiation on people’s health to determine whether together with other telecommunications devices and appliances, such as microwave ovens, they are long-term carcinogenic sources.
While there is no universal measure to determine how much radiation from the phone is harmful, the German certification of respect for the environment ‘Der Blaue Engel’ (Blue Angel) determined that all the Chinese phones presented in this study more than double the allowed limit.
