  4. II. NATIONAL PROVISIONS Non-ionizing radiation environmental quality standards radiation (EQS-NIR) [0-300 GHz] are being developed. Maximum permissible limits for telecommunication activities (MPLs-NIR for telecommunications) [9 kHz-300 GHz], D.S. 038-2003-MTC.

  5. For workplace exposure Frequency range Electrical field strength (V/m) Magnetic field strength (A/m) Power density (W/m2) For public exposure Frequency range Electrical field strength (V/m Magnetic field strength (A/m) Power density (W/m2)

  6. Technical Standard on Radiofrequency Restrictions in Public Places As a directive supplementing D.S. 038-2003-MTC, on February 28, 2005, the Technical Standard on Radio Restrictions in Public Places (R.M. Nº 120-2005-MTC/03) was published. This technical standard establishes reference levels for public exposure in public places, defined as those places where it is considered that the public might be exposed to electromagnetic fields, such as: Schools (pre-school, primary, and secondary) Hospitals Health centers, and Clinics

  7. Reference levels for public exposure in public areas * Frequency range Electrical field strength (V/m) Power density (W/m2) * Either magnitude in the table above may be utilized: electrical field strength or power density, in accordance with frequency range.

  8. ORDINANCE REGULATING THE INSTALLATION AND OPERATION OF BASE RADIO STATIONS IN SANTIAGO DE SURCO DISTRICT ORDINANCE Nº 182-MSS This ordinance is a broad initial approach to the environmental impact of radio stations, taking particular account of: Impact of non-ionizing radiation Impact on the landscape and urban environment Impact of noise and vibrations Considering as prevention and mitigation measures instruments such as the Environmental Impact Study (EIA), Environmental Improvement Program (PAMA), compliance with the MPLs, consistency with the urbanization regime, minimum distances between stations, height limits, visual integration of towers and poles with the environment, authorization from owners’ associations in cases where facilities are installed on lots subject to the ordinary property regime, sworn accountability statement regarding the infrastructure’s capacity to withstand extreme risk conditions (earthquakes and tremors, high wind, etc.), including the great weight of base radio station (BRS) facilities.

  25. EVALUATION OF MOBILE TELEPHONES Utilizing the Ministry of Transportation and Communications’ list of approved equipment, a list of the 367 types of mobile telephones utilized in Peru was drawn up, and, utilizing information contained in international web pages, such as: http://www.sarvalues.com and http://www.mnfai.org, among others, the specific absorption rate (SAR) was obtained of the mobile telephones utilized in Peru, and exposure coefficients were calculated for a total of 205 mobile telephones.

  26. Mobile telephone maximum exposure levels are much higher than those of base stations. All mobile telephones authorized for use in Peru comply with the ICNIRP maximum permissible SAR limits. The exposure coefficient listed in each case is the maximum obtainable with the device. In most cases, to establish a connection, only a fraction of the maximum is required, as mobile phones are designed to work with the minimum power required to reach the mobile network.

  28. V. CONCLUSIONS AND RECOMMENDATIONS • The ICNIRP Non-ionizing Radiation Exposure Recommendations are accepted by the WHO, the ILO, and the ITU. They are the same standards as those implemented in many countries worldwide. After a process of bringing its standards and maximum permissible limits into line, Peru has accepted said recommendations as environmental quality standards and maximum permissible limits for telecommunication activities. • The national evaluation showed that the vast majority of values measured comply with the ICNIRP public exposure recommendations. Of a total of 174 measurement points, only nine points on Morro Solar exceeded the MPL, that is, 5.2%.

  29. CONCLUSIONS AND RECOMMENDATIONS • The maximum values of electrical fields generated by mobile services are relatively low, of the order of 5 V/m (1.5% of the ICNIRP recommendations). These values are much lower than the maximum values found in broadcasting and are consistent with values measured in other countries, such as in Belgium, Spain, and the United Kingdom. • As regards geographic distribution, the city with the highest levels of both electrical field strength and public exposure is Lima, on Morro Solar in Chorrillos District, where points exceeding the ICNIRP maximum recommended public exposure limits may be found. This site is followed by Mount Picchu, in Cuzco, where points of up to 60% of the maximum permissible public exposure limits may be found.

  30. CONCLUSIONS AND RECOMMENDATIONS • Measurements of MF sound broadcasting stations yield relatively high public exposure values. This is currently the case for station engineers and guards who do not know how much exposure they are receiving and do not necessarily have access to company-provided medical care. However, this situation can be overcome by utilizing workplace exposure limits, resolving these problems.

  31. CONCLUSIONS AND RECOMMENDATIONS • At our current state of knowledge, and taking account of research on effects carried out under the WHO International Electromagnetic Field Project, and measurements made by different countries worldwide, the evaluation showed that the risk of the effects of mobile telecommunication base stations is not significant. However, studies of mobile telephones under way worldwide must be followed very closely – especially those conducted in the framework of the International Electromagnetic Field Project – and precautionary policies applied.

  32. CONCLUSIONS AND RECOMMENDATIONS • It is recommended that buildings where mobile stations are installed be fenced off to prevent access to antenna areas. • In addition to the problem of perception of NIR, installation of base stations implies other environmental impacts that must be taken into account, such as visual impact, excessive weight of the structure on its lot, and others. Accordingly, it is recommended to co-locate mobile stations, since this will not detract from compliance with the ICNIRP standards but will mitigate environmental impact aspects.

  33. CONCLUSIONS AND RECOMMENDATIONS • In general, the problem of non-ionizing radiation from telecommunications is essentially one of perception of risk. • To manage public concern, it is recommended to conduct an ongoing mass media campaign on the topic of NIR, in order to avoid misperceptions of risk, and to implement precautionary policies consistent with the likelihood and scale of potential harm. • Lastly, it is recommended to establish an interdisciplinary team of experts on NIR who can issue reliable views and advise the general public and the government.
