“mobile devices are transmitters designed to be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons.”



ABC NEWS on Laptop Burns

Please note that there are "Reports of Skin Cancer developing  in the burned area".
NACST wonders what the cancer risk/effect will be with years of this lap use.

Laptops emit heat from the mechanical equipment at work inside them plus the radio frequency radiation they emit from the WIFI antennase. Please note that non thermal effects such as cognitive changes, oxidative stress and damage to reproductive organs occur at levels far far lower than levels that cause heating effects.

Sharma G. Burn Injury Caused by Laptop Computers, Ann Med Health Sci Res. Nov 2013; 3(Suppl1): S31–S32.

Abstract: Laptop burn is a real condition and medical reports indicate that using a laptop across the legs can indeed cause it. in very rare cases, the condition can cause damage leading to skin cancer. A 24-year-old man presented with an asymptomatic reddish brown pigmentation on the thighs. After an extensive work-up, burning caused by use of a laptop was observed. Burning was induced in 3 days by using laptop for 4 h daily. Laptop should be used in properly ventilated and air-conditioned rooms. The most effective way of preventing erythema is to use the laptop on the table or desk.

So far a few case reports about laptops causing burns have been published. Now for the first time, we report on a case, in which notebook-induced thermal injuries placed in a patient's lap resulted in severe second- and third-degree burns. As a consequence, a partial amputation of the left foot had to be performed. Furthermore, we measured maximum temperatures of 12 popular laptops, which were running full load for 3 h. For this experiment air circulation underneath the device was blocked in order to simulate surrounding conditions, which were present when the patient got injured. Although this setting may be the reason for most of all notebook burns, this kind of test has not been part of any scientific publication until now. Patients with lower extremity sensation, altered consciousness or decreased peripheral sensitivity have a higher risk for thermal injuries.

Arnold A. Laptop Computer–Induced Erythema ab Igne in a Child and Review of the Literature , Pediatrics October 4, 2010.
Abstract: We report here the case of a 12-year-old boy with erythema ab igne on his left thigh caused by the use of a laptop computer. This is the youngest of the 10 reported patients with this laptop-induced dermatosis since its first description in 2004. Erythema ab igne is a reticular, pigmented, sometimes telangiectatic dermatosis that is caused by prolonged exposure to a heat or infrared source. In laptop-induced erythema ab igne, the localization on the thighs and asymmetry are characteristic. The heat originates from the optical drive, the battery, or the ventilation fan of the computer.

Radiation from a Laptop


Microwave Absorption into the Body from a Laptop

The above picture shows the laptop microwave absorption into a grown male.

We would expect a larger area to receive the radiation in children,
especially the heart and internal organs.

Where are the studies with children and Laptops?
Children are not studied so we simply do not know.

Wrapped Microstrip Antennas for Laptop Computers Guterman et al 2009

Laptops emit microwave  radiation just like cellphones.
Every parent should know:
  • Laptops were tested at 20 cm from the body.
  • Laptops have fine print warnings about keeping a distance.
  • They send out bursts of radiation while they are connected to the internet and  also while they are simply on.
  • Streaming video produces the highest rates of radiation.

100x Radiation on your Lap?
"Laptops"  technically are not supposed to be on your lap. That would be "improper" consumer use.  They generate high electromagnetic field radiation and the SAR could be up to 100 fold on your lap as opposed to the table.  Regulations ONLY consider use at 20 cm (8 inches) from the body.  Do you ensure your children have laptops at 8 inches away? 

What can I do?

1. Use a Wire.
2. Turn the Wifi Off
3. Turn Airplane Mode On.
4. Keep  Laptops on table.

Simple Steps

just make sense.
