| Título | Determination of the radiated power through ground-based field strength measurements in the frequency range from 30 MHz to 6000 MHz |
| Resumo | The radiated power of a transmitter is one of the most important parameters which characterise a transmitter and its emissions. Usually, it is not possible to measure the radiated power directly. However, there are two different methods to determine the radiated power indirectly. The first method would measure the transmitter output power and calculate the radiated power by taking into account cable losses and antenna gain. The second method measures the field strength and calculates the radiated power by taking into account the measurement distance and the propagation loss. The purpose of this ECC Recommendation is to provide common measurement methods which will enable CEPT administrations to determine the radiated power of a transmitter in the frequency range from 30 MHz to 6000 MHz from field strength measurements reducing as much as possible the uncertainty of the measurement. |

| Título | Basic standard for the in-situ assessment of exposure to radio frequency electromagnetic fields in the vicinity of a broadcast site |
| Resumo | This document specifies the method for assessing overall exposure from all fixed radio frequency sources at a broadcast site. This assessment can be applied at any time but is carried out when the exposure situation changes in or around the aforementioned site. This document can play an essential role in the coordination of different stakeholders, with respect to ensuring EMF exposure compliance in the vicinity of a broadcast site especially for equipment installed within the site. |

| Título | Survey of radio wave exposure 2022 | ||
| Resumo | In March and April 2022, ARPANSA scientists measured public exposure to radiofrequency electromagnetic energy, also known as radio waves, at 50 sites across Melbourne. At the locations measured, the public’s exposure to radio waves from wireless technology was found to be well below the limits in the Australian safety standard. The measurements collected in Melbourne represent the typical radio wave exposures that ARPANSA would expect to see in other major Australian cities. | ||

| Título | Localized human exposure limits for radiofrequency fields in the range of 6 GHz to 300 GHz |
| Resumo | Health Canada is providing recommendations for localized human exposure limits for radiofrequency electromagnetic fields (EMF) in the range of 6 GHz to 300 GHz. These have been developed at the request of Innovation, Science and Economic Development Canada (ISED) in order to support the establishment of new compliance requirements for wireless devices that will operate in this frequency range. These localized human exposure limits are recommended in scenarios where wireless devices operating in the 6 GHz to 300 GHz range are held close to the body, such as smartphones and tablets, including some 5G-enabled devices. |
