5 Tips to Protect Kids From Cellphone Radiation During Holiday Travel

If you're traveling this holiday season, chances are your kid will have a device in his or her lap for at least part of the trip.

Don't feel bad. We get it. Traveling with kids is harder than lifting a memory foam mattress.


Anything using a Wi-Fi or cell signal emits some amount of radiation in the form of radiofrequency energy, including smartphones, tablets, Kindles, laptops and smartwatches. The amount of radiation depends on the device and the strength of the signal.

Research from the National Toxicology Program found that lab animals exposed to radiofrequency radiation at levels similar to those emitted by cellphones had a greater likelihood of developing brain cancer and heart tumors. This study offers valuable insight into the potential risk to people, including future exposure to 5G wireless networks.

Fortunately, there are a few things you can do to reduce the amount of radiation those devices give off and how much your kid is directly exposed to.

1. Get It Out of Your Child's Lap

Make space between the device and your kid's body. Even a few inches make a big difference.

Instead, put the device on a portable lap desk or airplane tray table to keep it from resting on your child's body. (Portable lap desks are easy to find, even in foldable travel versions. As a bonus, they're great for eating and drawing in the car, too.)

Also, teach your kids to carry their cellphone in a backpack or purse—somewhere other than next to their body in a pocket. This is especially important when kids are on a call—phones emit higher radiation when they're transmitting a call or data.

2. Keep Devices in Airplane Mode

This is especially important when the signal is weak or when you're moving—like in a car or train. The harder a device has to work to find a tower, the more radiation it releases. So as you're speeding along, cellphones and cell-enabled tablets are working extra hard to connect with towers along the way, and your kids are getting a bigger dose of radiation. When they're in airplane mode, devices don't send or search for a signal and therefore don't emit radiation.

You can minimize your kids' pushback about this by downloading apps and videos before leaving home so you don't stream them while you travel. Many apps can be played without Wi-Fi or cell signal, and as of this writing, Netflix and Amazon's Prime Video allow users to download TV and movies via their iPhone app.

3. Always Use Headphones or Speaker Mode for Calls

Cellphones emit their highest radiation levels during phone calls, and that level goes up even more when the signal is weak or moving. And because children's small heads and thinner skulls can absorb more radiation, regular cellphone use puts them at increased risk of potentially harmful exposure. Teach kids to use headphones or speaker mode every time they make a call (and put the phone somewhere away from their bodies while they talk, like on a table or arm rest, or in a cup holder).

4. Don't Let Kids Sleep With Their Devices

Kids shouldn't sleep next to their devices, and especially not with them under their pillow. According to Pew Research Center, 90 percent of young adults sleep with their phone in or right next to their bed. Even when they're not being used, cellphones emit a small amount of radiation, and small amounts—of almost anything—can add up to big trouble for children. Plus, there's a ton of research which shows that heavy device use, especially right before bed, messes with our circadian rhythms and ability to fall asleep. And as every parent knows, that's the last thing you want to happen with your kids, especially when you're on your way to a week at Grandma's house.

5. … or Next to the Wi-Fi Router

When you do finally get to Grandma's, don't put the kids' air mattresses next to the router in her office. Scientists don't know what the effects of Wi-Fi are on human health, because most studies, including the research that gave rise to cellphone radiation being classified as a possible carcinogen, have been done on conventional cellphone radiation. But the closer the source of radiation, the more kids will absorb. So some experts recommend placing the router in an area of the house where people spend fairly little time, rather than near beds.

And of course, if you're willing to go all out to help your kids avoid radiation exposure, there's always the radical option of giving the screens a rest and breaking out the markers and drawing paper instead.

Tropical forests globally are being lost at a rate of 61,000 square miles a year. And despite conservation efforts, the global rate of loss is accelerating. In 2016 it reached a 15-year high, with 114,000 square miles cleared.

At the same time, many countries are pledging to restore large swaths of forests. The Bonn Challenge, a global initiative launched in 2011, calls for national commitments to restore 580,000 square miles of the world's deforested and degraded land by 2020. In 2014 the New York Declaration on Forests increased this goal to 1.35 million square miles, an area about twice the size of Alaska, by 2030.

Compassion Over Killing

Do you think almond milk comes from a cow named Almond? Or that almonds lactate? The dairy industry thinks you do, and that's what it's telling the Food and Drug Administration (FDA).

For years, the dairy industry has been flexing its lobbying muscle, pressuring states and the federal government to restrict plant-based companies from using terms like "milk" on their labels, citing consumer confusion.

A driver planning to make the trek from Denver to Salt Lake City can look forward to an eight-hour trip across some of the most beautiful parts of the country, long stretches with nary a town in sight. The fastest route would take her along I-80 through southern Wyoming. For 300 miles between Laramie and Evanston, she would see, according to a rough estimate, no fewer than 40 gas stations where she could fuel up her car. But if she were driving an electric vehicle, she would see just four charging stations where she could recharge her battery.

A petrochemical plant near Houston continued to burn for a second day on Monday, raising questions about the quality and safety of the air.

The Deer Park facility is owned by Intercontinental Terminals Company (ITC), which said the fire broke out at roughly 10:30 a.m. Sunday. Seven tanks are involved, the company said, and they contain naptha, xylene, "gas blend stocks" and "base oil."

"It's going to have to burn out at the tank," Ray Russell, communications officer for Channel Industries Mutual Aid, which is aiding the response effort, said at a news conference. It could take "probably two days" for that to happen, he added.

The hillsides dyed orange with poppies may look like something out of a dream, but for the Southern California town of Lake Elsinore, that dream quickly turned into a nightmare.

The town of 66,000 people was inundated with around 50,000 tourists coming to snap pictures of the golden poppies growing in Walker Canyon as part of a superbloom of wildfires caused by an unusually wet winter, BBC News reported. The visitors trampled flowers and caused hours of traffic, The Guardian reported.

A controversial pesticide test that would have resulted in the deaths of 36 beagles has been stopped, the Humane Society of the United States (HSUS) and the company behind the test announced Monday. The announcement comes less than a week after HSUS made the test public when it released the results of an investigation into animal testing at Charles River Laboratories in Michigan.

"We have immediately ended the study that was the subject of attention last week and will make every effort to rehome the animals that were part of the study," Corteva Agriscience, the agriculture division of DowDupont, said in a statement announcing its decision.
