Radiation emissions from base stations
The transmission of radio frequency (RF) waves makes mobile communication possible. RF waves are electromagnetic fields
(EMF), and their possible impact on health is a frequently discussed issue in the mobile telecommunications sector. Radiation
is produced by mobile devices and base stations and there has been a great deal of research undertaken since the early 1990s
related to EMF. Singtel frequently monitors the latest developments and publications.
The World Health Organisation (WHO) has been very active in promoting research and awareness of possible EMF health impact
and states that a large number of scientific studies have been performed over the last two decades to assess potential health
risks. They currently conclude that no adverse health effects have been established as being caused by EMF in everyday mobile
phone use5. |

In Singapore, the Centre for Radiation Protection (CRPNS), an office of the National Environment Agency, is responsible for all
matters relating to EMF exposure. The permitted levels of radiation from mobile phones and base stations in Singapore is based
on the WHO recommended guidelines and International Commission on Non-Ionising Radiation Protection (ICNIRP) standards.
CRPNS current advice is that levels of public exposure to EMF from base stations and mobile phones in Singapore is normally
well below international guidelines, and much lower than levels where health risks are likely to be present6.
The radiation levels from Singtel’s mobile base stations are within the ICNIRP acceptable limits and mobile phone handsets sold
at our stores must comply with regulatory guidelines set out by CRPNS and IDA.

Biodiversity
Two of Singtel’s operational activities have a potential impact on biodiversity, specifically cable laying and base station placement. The loss of
biodiversity is a global concern and one which Singtel acknowledges as an important matter.
When laying cables and choosing base station sites, we will first assess any potential environmental issues, including biodiversity. Should our
cable laying routes or base stations affect any natural areas, we will consult the National Parks Board (NParks), and with their advice make a
judgement on how best to proceed and minimise or eliminate any adverse impact. With undersea cable installations, minor localised seabed
disturbance is unavoidable although we do take into account, where possible, any adverse environmental impact to water quality and the
natural environment.
During the reporting period, we have not encountered any significant biodiversity issue. |
