| Título | Radiated EME exposure levels – Prediction methodologies |
| Resumo | Radiated fields from cellular telephone base stations must comply with safety limits imposed by the Australian Communications Authority (ACA). The limits are described in the ACA Standard: Electromagnetic Radiation – Human Exposure Standard 1999. The purpose of this technical report is to provide a protocol that allows a prediction of the estimated exposure levels to show compliance with the ACA Standard prior to installation of the radiating antennae. The assessment is a prediction of RF EME levels that are a result of line-of-sight propagation from the antennae to a point that is considered to be in the centre of the horizontal beam pattern. |

| Título | Measuring Non-Ionizing Electromagnetic Radiation (9 kHz – 300 GHz) |
| Resumo | This Recommendation specifies in-situ measurement procedures in order to assess electromagnetic fields for the purpose of comparison against limits for human exposure applying in CEPT countries (e.g. EU 1999/519/EC,ICNIRP guidelines, national limits,…). It is important to note that this recommendation does not itself standardise or define exposure limits, or cover human exposure to radio signals. |

| Título | Levels of Radiofrequency Radiation from GSM Mobile Telephone Base Stations |
| Resumo | This report presents field survey measurements data and provides information on the levels of radiofrequency (RF) radiation to which members of the public may be exposed from mobile telephone base stations. The measured RF electromagnetic energy (EME) levels are compared with the maximum permitted limit for non-occupational exposure with respect to the Radiocommunications (Electromagnetic Radiation Human Exposure) Standard 1999 which specifies a maximum non-occupational exposure limit of 2 W/m2 (equivalent to 200 μW/cm2) at relevant base station frequencies. Although the focus of the survey was on measuring the RF EME emission levels from the digital Global System for Mobile communication (GSM), the environmental RF EME measurement component of the project involved investigating the EME levels from other sources, including the analog Advance Mobile Phone Systems (AMPS), VHF TV, UHF TV, AM radio, FM radio and Paging. The results clearly demonstrate that the RF EME emissions from GSM base stations are several orders of magnitude below the maximum permitted limit. A worst case RF EME power flux density prediction, based on our measurements from GSM base stations, is 0.178 μW/cm2 (the 200 μW/cm2 limit of power flux density is at least 1,000 times this predicted value). However, the average RF exposure level from GSM base stations is considerably less, at 0.0016 μW/cm2 (the 200 μW/cm2 limit of power flux density is at least 100,000 times this average value). Measurements of the fixed site environmental RF EME power flux density levels indicate that, relative to the maximum exposure limit permitted in the standard, after adjusting the exposure limit with respect to the frequency of the signal, the highest environmental RF exposure was FM radio (0.0259 μW/cm2), with the 200 μW/cm2 limit of power flux density at least 7,000 times this value. |

| Título | Stations de base pour téléphonie mobile (GSM) – Recommandation sur les mesures |
| Resumo | La présente publication, destinée aux autorités d’exécution et aux laboratoires de mesures, contient des instructions sur la manière de mesurer et d’évaluer le rayonnement émis par les stations de base de téléphonie mobile des réseaux GSM. Elle sert en même temps de base à l’accréditation des laboratoires effectuant de telles mesures. L’accent porte sur les mesures effectuées à l’intérieur des bâtiments. Après un bref aperçu de la technique GSM, les dispositions déterminantes de l’ordonnance sur la protection contre le rayonnement non ionisant (ORNI) sont expliquées et précisées. Suivent des recommandations détaillées concernant la méthode et les appareils de mesure, le traitement de l’incertitude de mesure et une évaluation des résultats conforme à l’ordonnance. Une des annexes concerne la détermination de l’incertitude de mesure, une autre l’extrapolation d’un résultat de mesure à la capacité maximale de l’installation émettrice. |

| Título | Occupational Exposure to Electromagnetic Fields: Practical Application of NRPB Guidance |
| Resumo | Current NRPB guidance on exposure to electromagnetic fields was published in 1993. Since then, NRPB has gained considerable experience of the practical implementation of this guidance in industrial environments.This report describes strategies that have been developed to allow comparisons to be made between measured exposure levels and the NRPB restrictions on exposure in situations where the straightforward application of the investigation levels may not always be appropriate. |
