Health Risks of Microwave Frequencies/Radio Frequencies

Today the use of microwave frequencies and radio frequencies for communication and connection is very common. We can often see these devices attached to radio and television communication towers, satellite systems, radars, cellphone base stations, mobile television transmitter, and canopy antennas for the Internet like Smart Bro. Almost every area in our country has a communication tower, a base station and microwave antennas.


There are two types of spectrum, the non-ionizing and the ionizing spectrum. Non-ionizing are those who emit frequencies like infrared, ultraviolet, microwave, visible light, etc... Example of Ionizing spectrum are the X-rays and the Gamma Rays. That is why we often see a warning sign outside x-ray rooms.
Microwave and radio frequency radiation may be transmitted, reflected, or absorbed upon striking an object. So humans as the most possible recipient of this frequency will surely be affected.

Health Risk

It is known that Ionizing spectrum frequencies are more likely to affect humans because these frequencies contains tremendous amount of energy and penetration power and will surely change the molecular structure of any human. On the other hand, non-ionizing spectrum frequencies are not as harmful as the ionizing frequencies but still they can have effects to humans.

It has been known for many years that exposure to very high levels of RF and microwave radiation can be harmful due to the ability of these frequencies energy to rapidly heat biological tissue. This principle is used also in a very common appliance called the Microwave Oven.

Since humans does not have very effective means to dissipate heat generated from these frequencies biological tissues burn. Two areas of our body is very vulnerable, the eyes and the testicles because blood flow from these body areas is low meaning they have very a very slow rate of dissipating heat. This is the reason why people are advised to stay away from structures that emit frequencies.

Another known effect is the formation of cataracts in eyes. Several humans and animal specimens proved this because of exposure to frequencies.

Radio frequencies has also been linked to cancer. Although it has been proven by the formation of tumor in animals exposed to these frequencies still they fail to find the link.

Studies are still ongoing on several laboratories about this issue.
