Testing The Intensity of Laptop Radiations

(adsbygoogle = window.adsbygoogle || []).push({});

There are strong indications that  Laptop radiations have adverse health effects on human health.  Although there are conflicting opinions on whether or not such laptop radiations are harmful. Studies have continued to show that humans have limited intensity of radiation their bodies can withstand beyond which might become harmful and dangerous to the well-being of man.


Laptops are portable computers that can be carried around in a handy way and even placed on laps to work.

There have being various studies on electromagnetic radiations from electronic devices especially laptop computers .

Truth be told, all other electronic gadgets such as television, cell phones, microwave ovens, Wireless routers etc.  emit such radiations as well, but what makes those of laptops critical is the fact that laptops are often carried on laps or even much closer to human systems .
The said closeness to human bodies  shortens  the distance between the electromagnetic frequencies waves  and the human body.

(adsbygoogle = window.adsbygoogle || []).push({});

It is believed   also that the nearer such waves to the human body,  the more the intensity and the higher the risk of damaging cells thereby possibly  leading to cancer.

Ionizing Radiations

Ionizing radiation is an energy type released by atoms that move in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The automatic continuous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.

World Health Organisation- W.H.O report of 2012 declared after research that certain amount of such radiations beyond a particular level can be injurious to human health and possess the tendency to cause health hazard. According to W.H.O the following facts were deduced from their findings.
