Tablet radiation is a serious concern these days. If you want to know which tablets have the lowest radiation, or SAR value, or which tablets have the highest radiation, you’re in the right place!
There are a few ways you can find SAR Values for tablets and we’ll go over those here. However, I put a handy chart together and included the newest and most popular cell phone models in 2022.
Jump straight to the Tablet radiation chart now! (it includes 80 current models in 2022).
What’s the lowest radiation tablet? The Samsung Tab S8 (Model SM-X700) has the lowest SAR value at 0.231 W/kg over 10 grams when used against the body of the models researched in this article in 2022.
What’s the highest radiation tablet? The Microsoft Surface Pro LTE (Model 1807) has the highest SAR value at 1.841 W/kg over 10 grams when used against the body of the models researched in this article in 2022.
Generally, models with cellular capability will have higher SAR values, as you will see in the chart.
Over the past decade, tablet and iPad usage, as well as the use of computers, cell phones, and Wifi, has significantly increased.
Most people who use a tablet or other devices regularly throughout their day have a continuous exposure to non-ionizing RF (radiofrequency) radiation.
Is this electronic device safe? We know electronic devices emit radiation and some emit more than others. Let’s dig in.
Tablet Radiation – What is Specific Absorption Rate (SAR)?
A key consideration in worrying about exposure to radiation is a concept called the specific absorption rate (SAR), which is a measure of how fast the human body absorbs energy when exposed to radiation.
Specifically, SAR refers to the energy taken in per kilogram of tissue, which is represented by watts per kilogram, or W/kg.
The concern is that tissue has a specific rate of absorption “limit” and that anything past that can cause cellular damage.
This is particularly dangerous when in terms of microwave frequency, or microwave radiation which builds and causes heat, but all RAF radiation can build to cause heat, including tablets and cellphones.
Too much heat and absorption turns into cellular damage and in turn, can cause cancer.
The SAR matters because though the FCC has limits and standards in place for all the cellular network devices, they don’t consider:
- That our bodies get bombarded at certain times with RAF radiation, which has a compounding effect, meaning each individual source of radiation is additive and makes exposure more dangerous
- The microwave heating effect occurs below the SAR limits set by the FCC
Basically, for smaller people, the rate of absorption will be higher, leading to more cause for concern. So there’s a baby in our house, we need keep our baby at a safe distance from cellphone.

Apple provides this information regarding RF exposure:
iPad has been tested and meets applicable limits for radio frequency (RF) exposure.
Specific Absorption Rate (SAR) refers to the rate at which the body absorbs RF energy. The SAR limit is 1.6 watts per kilogram in countries that set the limit averaged over 1 gram of tissue and 2.0 watts per kilogram in countries that set the limit averaged over 10 grams of tissue. During testing, iPad radios are set to their highest transmission levels and SAR is evaluated in real-time, over time intervals as specified by applicable regulations. iPad is evaluated in positions that simulate use against the body.
Apple uses the latest approved regulatory methods adopted in the industry for testing and managing device radios to meet RF exposure limits. These methods track radio usage and RF exposure in real-time and manage power to ensure that the iPad complies with applicable RF exposure limits.
Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified.
Microsoft provides this information on their SAR information page:
What is a SAR value?
Every mobile device model is tested for radio wave emissions. Using an internationally standardized method that meets government and regulatory requirements, a measurement is made to determine how much electromagnetic energy is absorbed by body tissue. This gives the SAR (specific absorption rate) value. Governmental and regulatory agencies have established SAR limits under which mobile device use has been determined by them to be safe. All Microsoft devices are designed to comply with the relevant governmental SAR level.
Important user information

Type of Radiation Emitted by Tablets
When cell phones (check out cell phone radiation levels here) became extremely commonplace, the world’s governments and scientists were given pause: was it safe to have these little devices pressed against our heads for any duration during the day?
We know that at certain levels, radiation damages cells and can cause cancer, but what about in something as small as a mobile phone or a tablet? Are they dangerous, and if so, why?
Tablets and cellphones emit radiation, which can be broken down into two additional subcategories: ionizing and non-ionizing. Some examples of ionizing radiation are:
- Radiation from space
In other words, they type of radiation you want to stay away from unless absolutely necessary.
Examples of non-ionizing radiation include:
- Radiofrequency waves
- Power frequency (as emitted by most electronics while they’re simply plugged in)
The difference between these two types of radiation are the wavelengths, or how intense the energy of the electromagnetic waves, are.
High energy waves damage cells; this is the same reason exposure to unshielded sunlight can cause skin cancer.
Luckily, tablets don’t emit this hyper-dangerous type of electromagnetic radiation, just the radiofrequency type.
With that said, however, the radiofrequency radiation emitted by tablets still causes heating, and there are many studies done that suggest at high doses it can also be carcinogenic.
Health Implications of Electromagnetic radiation
Since radiofrequency radiation exposure isn’t as high energy as ionizing wavelengths, it isn’t as immediately dangerous.
This would be true if we only used cell phones and tablets for a few minutes out of the day, but most people are on their devices for hours.
Some studies indicate that even minor appliances and the electricity they emit — which is also an extremely low frequency radiation like RF radiation — are possibly carcinogenic.
The difference between your fridge and your tablet, however, is that you don’t have the fridge inches from your face for hours a day, or sitting in your lap while you watch a movie. You certainly aren’t carrying your fridge around in your backpack or pocket, either, so with your tablet or mobile phone use, you’re constantly bombarded with RF radiation.
As we stated before, the potential for damage to your cells exists in both the energy-level of the radiation and the length of exposure.
Is Tablet Radiation Exposure Harmful?
While tablets, mobile phones are not particularly energetic, most people have at least casual interaction with computers or wireless device on a daily basis.
Couple that with tablet use, either for leisure or in our jobs, and you have a tremendous amount of low-grade energy wavelengths bombarding our bodies on a daily basis.
According scientific evidence, to the World Health Organization, this can be potentially cancer-causing.
Additionally, the rise of a specific type of brain tumor — glioblastoma— mirrors the increase in availability of tablets and cellphones.
An Italian study on the effects of casual cellphone use on tumor generation found that there appears to be a direct link to cell phone and, by extension, tablet use.
A few studies indicated that mobile phone users and tablet users who use the devices for long period everyday are likely to absorb massive amount if radiations as their radiation exposure is directly proportional to the time of use. It causes various health risks like tumor in thyroid gland, developing tumors at head and neck region and the users are more likely inclined to developing cancer in long run.
EMF radiation has been a very sensitive thing nowadays. Various harmful effects due to massive electromagnetic waves from electronic devices like cordless phones, tablets etc we are silently developing many health problems. Even, if we’re using simple Kindle which can’t be called a standard tablet in anyway, then also we’re in constant threat from its emitted blue light. We have covered a separate piece on it, here.
Various public health monitoring agencies also expressed their worries about rising case of brain tumours, risk of thyroid cancer. Adverse effects of rf emf specially in close proximity are dangerous in long run for the regular users of tablets as most tablets emits more electromagnetic waves than the specified limit.
AN international journal has published a result of SAR of the well known electronics brands. All these devices in the market emit higher radiofrequency waves than the limit set the Government. Due to high radiofrequency exposure various health problems like skin cancer, optic tumour, brain tumours etc have been developing at massive rate for past several decades. Because of the direct contact the exposure levels go up. Even if we put our device at airplane mode, it keep emitting radiation.
How do you protect yourself from tablet radiation?
At this point, you’ve probably started to wonder how you can protect yourself from all these RF waves, right? Of course, you could just chuck the thing out the window and live in a cave, but that’s not a good solution to anything. Let’s take a look at some daily practices that will make your tablet use safer.
- When you’re not using it, take the extra second to turn it fully off. (Here’s an article on step by step walkthrough of disconnecting wifi.)
- Keep your tablet charging away from people, like in a specific corner of the room.
- Don’t have cellular or WiFi connected if you’re not using it.
- Never sleep with it near your body, especially your head.
- Keep your tablet away from kids, and if they must use them, limit tablet time.
- Consider buying a radiation shield — they’re inexpensive and easy to apply. This is a good tablet radiation shield from a reputable company.
- Avoid using it when your signal isn’t great; this makes the tablet work harder to find a connection and in turn, emits more radiation.
- If you use your tablet to communicate, either do visual communication where the tablet can be at arm’s length, or use speakerphone options.
- Place your tablet on a surface when working, if possible, to avoid sitting it directly on your body. If you are at an airport or other situation where there are no tables, put a backpack or purse between you and the tablet.
- If a child needs to speak on the tablet- say, if grandma is calling — use it on speaker mode. Children’s little bodies absorb radiation faster than adults. (Check out if iPhone Radiation Harmful to Babies)
Conclusion: Infrequent, intelligent tablet use is critical
Now you know more about tablets, radiation and absorption than you probably ever wanted to, but it’s important that you understand how these daily-use items can affect our health. Sure, using a table every once in a while wouldn’t ever be a big deal, but people use computers every single day, for work and play, and that much radiation exposure adds up.
With a low SAR tablet choice, limited exposure times and proper storage/charging, you can dramatically reduce your chances of long term damage. Also discuss and practice good electronics habits with your kids, ensuring they too are safe.
