Cell phone towers are still relatively new, and many people are understandably concerned about whether the RF waves they give off might possibly have health effects. At this time, there’s no strong evidence that exposure to RF waves from cell phone towers causes any noticeable health effects.

What does radiation feel like?

Early and late effects of radiation therapy

The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area.

How can I check radiation in my area?

The government of India has launched a website tarangsanchar.gov.in to help you check the radiation levels in your area. Just log in to the website, switch on your device location or enter your address and check out the number of cell-phone towers in the area.

Is cell phone tower radiation safe?

The World Health Organisation’s International Agency for Research on Cancer (IARC) says radiation from cellphone handsets and towers is “possibly carcinogenic to humans” and may cause glioma, a type of brain cancer. Towers are more dangerous than handsets because they emit greater-intensity radiation 24X7.

Does Airplane mode stop radiation?

Does Airplane Mode Stop all Radiation? Airplane mode terminates all wireless connections so yes, it does cut the vast majority of mobile phone radiation. Still, your phone will always emit some level of radiation provided it is switched on.

Is it harmful to sleep with phone?

Sleeping with your phone near you can be harmful for your body functions and tend to limit the production of many significant hormones. Place the phone several feet away from your bed if you’re not going to switch it off. It has become a trend, especially for young people to sleep with their phones next to them.

How far away should you sleep from your phone?

Your phone should be at least three feet away from your bed to limit exposure to radiofrequency energy. If you need to use your phone as an alarm, turn on airplane mode to prevent it from sending or receiving calls and text messages.
