Yes there definitely is.
Try the worlds most protective Cell Phone Radiation shields that provide 100% Protect.
Cell Phone Radiation EMF Shields are designed to eliminate noxious radiation emissions. Cell Phone Radiation Shields create a healthy life-force energy field which scatters the microwave emission, reducing the 'hot head' syndrome when using your phone.

The strong suggestion is that phone companies are aware of EMF and radiation problems" says Simon Best, editor of Europe's Electromagnetic Hazard and Therapy Magazine. Simon Best believes that these firms are preparing for a doomsday scenario, in case they are forced to include protective devices with every new mobile phone sold. The patent documents were uncovered as the three big cell phone makers face multi-million dollar legal actions by people claiming their health has been damage by cell phone usage. http://www.orgoneenergy.org/faq-radiation-protectors.html
Cell phone industry has continually insisted there is no proven link between cell phones and health problems. Patents suggest Nokia, Ericsson and Motorola believe otherwise. Two Nokia patent applications filed in 1995 and 1998 admit that, in the "worst case" that there is absolute scientific proof of radiation problems. http://www.orgoneenergy.org/mobile-radiation-shield
Protect yourself and never use a Cell Phone without Radiation Shielding, to prevent Brain Tumours and Cancer.
Through the phone
what is the essential concept of underlying radiation protection
To reduce the effects of cellphone tower radiation, you can limit your exposure by keeping your distance from the towers, using hands-free devices or speakerphone when making calls, and minimizing the time spent on calls when in close proximity to the towers. Additionally, you can consider using shielding materials or devices that are designed to block or redirect radiation.
You can create a Faraday Cage with aluminum foil.

This is disputable, but some people claim that the radiation from cell phones is harmful to your brain.

NO!
The ozone layer gives us the protection from radiation
Not really. You don't have anything to worry about carrying your cell phone in your pants pocket.
The Freyssinet system provides leakage protection and radiation protection systems.
Lead, Water, Aluminum... something!
