Radio frequency waves and electromagnetic waves have been identified as one of the major health risk factors for humans. With most of the population relying on smart phones and wireless internet for survival, the amount of radiation these devices emit is a cause for concern. But you can invest in a decent anti-radiation cell phone case and prevent such radiation from affecting your health with long-term use. Here are our top three picks:

1. DefenderShield
DefenderShield is one of the best anti-radiation cell phone cases you can buy that is also approved by the Federal Communications Commission (FCC). The case manages to block out 99.99 percent of electromagnetic radiation. The product is designed with multiple layers of shielding without it affecting the device’s ability to send and receive a proper signal. Their proprietary DefenderShield technology additionally blocks 5G wireless, WiFi, and Bluetooth radiation. The material also manages to dissipate any heat within the layers. DefenderShield anti-radiation phone cases are designed for popular Apple and Android smartphones.

2. SafeSleeve
SafeSleeve is another popular alternative that is certified by the FCC. The anti-radiation cell phone case is designed to counter 99 percent of direct 5G, WiFi, and cellular radiation. Additionally, the materials are designed to bounce back at least 92 percent of extremely low frequency (ELF) radiation adsorbed form batteries, AC power adapters, and other external devices. Made with durable military grade materials, the cell phone case can survive scratches and drops to protect your expensive phone. SafeSleeve cell phone cases are designed for iPhones, iPads, laptops, and select Android phones.

3. RadiArmor
RadiArmor introduces a range of products that are designed to deflect radiation from your iPhone, iPad and laptops. It offers more products including phone sleeves, EMF-blocking fabric, laptop pads, and even bed canopies that can deflect up to 99 percent of RF waves. Many of the cases include radio-frequency identification (RFID) protection so you can safely store your credit cards and travel without worrying about unauthorized scans. The cases also feature an additional layer of TPU rubber along the edges to protect your phone from dings and dents due to accidental drops.
