The damage caused by excess to electromagnetic fields radiations are the global health problem being the children the most, afected by this reason. In this work was checked the electromagnetic enviroment of 4 internment cubicle of "William Soler " Hospital intensitive terapy room, for it purpose was used Emdex II gaussimeter in order to make measurements,computer tools to process the data obtained in them and the recommendation emited by international commission for the protection against non-ionizing radiation (ICNIRP) in 2010 as a standard for comparisons, the measurementwere maked according to the established by protocol in cientific literature, according to hepidemiology standard of cuban health Ministry. The result of the measurement obtained were lower than recommended by ICNIRP, so the result are positive. [ABSTRACT FROM AUTHOR]

A study about the influence of joint use of nanosilica and ATH as fillers on room temperature vulcanized silicone rubber used in the outdoor insulation is carried out. This study is made by comparison between room temperature vulcanized silicone rubber coating with nanosilica and ATH as simultaneous fillers and room temperature vulcanized silicone rubber coating with nanosilica and ATH as independents fillers. The parameters of this comparison are: erosion resistance, circulation of leakage currents under salt fog conditions and hydrophobicity loss. The results of this work show a better development of room temperature vulcanized silicone rubber coating with nanosilica and ATH as simultaneous fillers than room temperature vulcanized silicone rubber coating with nanosilica and ATH as independents fillers.

The work reveals the study of the electromagnetic environment in several computer laboratories belonging to the Universidad Tecnológica de La Habana "José Antonio Echeverría" (CUJAE). The main objective is to analyze the behavior of the existing magnetic field in these laboratories, taking into account the different situations that may arise. For the measurement of the magnetic field, the gaussimeter model PCE-G28 was used and for the characterization of the magnetic field of the laboratories a measurement protocol was developed, based on the analysis of international standards. The results obtained between 0,01 µT and 9,31 µT reflect the areas of greatest intensity, generally coinciding where the electrical protection panel is located and where the power supply enters the laboratories. Although the measurements do not exceed the limits recommended by International Commissions on non-ionizing Radiation Protection (ICNIRP) in 2010, some prevention measures were recommended as a result of the characteristics observed during the days of measurement.

Nowadays, the problems associated with the use of the non-ionizing radiations, among them the sources they generate magnetic fields of low frequency (50-60 Hz), have retrieved a growing interest between the scientific community. The agglutination of medical equipment according the constructive disposition of the area in which find, lead to invisible interference that could affect the functioning itself. For this reason, this working group decided to perform measurements of low-frequency magnetic field. It was used the instrument of measurement EMDEX II and it was take into account different situation in a neonatal neurophysiology test consultation. It was concluded that there are external interferences that reach the medical equipment is located. The values of magnetic field issue and its origin were obtained. It recommends to move the medical equipment to another space where exist less intensity of magnetic field. [ABSTRACT FROM AUTHOR]

The electrical network is one of the least detected sources of electromagnetic interference, but it causes adverse effects on the medical equipment that is in its radius of action. The objective of this work is to analyze the effect of the magnetic field on the signal emitted by the Audix V equipment. A magnetic field generator, a gaussmeter, a signal simulator and an Audix equipment were transmitted. The research was carried out, following a methodology developed from different methods found in the literature. Screenshots of the signals emitted by the Audix V with visible influence on the parameters that characterize it were obtained by applying field values even below the 3.77 µT allowed by the IEC. It was concluded that there may be an error in the diagnosis due to the deformation caused by the electromagnetic field on the characteristics of the signal. [ABSTRACT FROM AUTHOR]
