A Team Of Researchers At The Center

A team of researchers at the Center for Biomedical Technology (CTB) of the Polytechnic University of Madrid (Spain) has created a pocket instrument capable of perceiving including radio signals between the band of 50 MHz to 6 GHz and store this information in a non-volatile memory. This measurement system enables storage and then analyze the data and to know the exposure that a person can have daily to electromagnetic radiation or for prolonged periods of time.

The needs of today’s society, in which new technologies and communications have emerged as the bastion of development, involve the continued introduction of new transmission systems. These systems work by emitting electromagnetic waves, so there has been a considerable increase in environmental radiation levels to which the population is exposed.

The increase in the number of issuers, coupled with ignorance of the characteristics and exact location of the emission sources, are extra impediments that make it very difficult real knowledge of changes in electromagnetic field levels in urban environments.

The increase in the number of issuers, coupled with ignorance of the characteristics and exact location of the emission sources, are extra impediments that make it very difficult real knowledge of changes in electromagnetic field levels in urban environments.

Concern about the possible effects of these fields have on human beings is a fact. The need for control of radio broadcasts by the competent authorities has led to the creation of specific regulations related to exposure to electromagnetic fields.

But the reality is that, despite the application of the rules, there is risk perception among citizens due to ignorance about the amount of radiation received, since, for a real and not theoretical measure, would be necessary to evaluate the radiation that each individual receiving at all times, at any point where you are either inside the buildings or outside. Only in this way you can properly know what the radiation levels of each are in their personal environment.

It is essential for the design of personal and portable devices, such as that developed in the laboratory of Bioelectromagnetism the CTB UPM. This new device is a pocket instrument, convenient to carry and able to receive radio signals falling between the band of 50MHz to 6GHz up to.

The frequency range is split into working channels of 10 MHz bandwidth, so that the received field strength in each channel and this information is stored in a nonvolatile memory is measured. The levels of electromagnetic radiation received by the individual carrying the device remain stored and then to analyze exposure over long periods of time.

The maximum sensitivity radio equipment designed for this would be in the order of -110dB and can withstand indirect radiated powers of hundreds of watts (maximum 300W) at distances of one meter from the source, without electronics equipment can be damaged.

The system further includes a digital visual and auditory indicator used to alert the individual of the existence of radio signals. This alert signal is programmable interesting aspect for users who want to control the levels of radiation to which they are subjected in their environments, whether working or not, meet the specified limitations.

According to its promoters, all these features make the instrument in a measuring apparatus suitable electromagnetic field for anyone who wants to control the levels of radiation to which it is subjected daily. The device has been protected by patent
