We are committed to providing safe and productive working environments for all government employees in buildings that we own and manage.
In line with this commitment, we are continually seeking improvement in the quality of the indoor environment in these buildings.
Guidelines for the management of 50Hz magnetic fields in office buildings (PDF, 610KB) are available to help departments and agencies develop their own safe and healthy building strategies.
This publication was produced prior to the current government.
What are electric and magnetic fields?
Electric and magnetic fields are invisible forces to which humans are constantly exposed. These originate from both natural and man-made sources, and the strength of these forces can vary greatly with both time and situation.
While no conclusive links between low level, low frequency electric or magnetic fields and impacts on human health have been established, we have elected to take a prudent approach to this issue.
In buildings, electric fields exist around any source of an electric voltage while magnetic fields are generated wherever an electric current is flowing through a wire or cable.
The strength of these fields varies with the voltage level and the amount of current flowing, and decreases with distance from the conductor.
Magnetic field testing
We have tested all government-owned and managed office buildings, and buildings which also house electricity sub-stations in the greater Brisbane area in 2008 and 2009, and extended this testing to all such buildings across Queensland in 2010–11.
All measurements taken in areas accessed by general staff have been well below the Australian Radiation Protection and Nuclear Safety Agency recommended guidelines.

Mineral House reports
Concerns about electro-magnetic field levels in Mineral House (41 George Street, Brisbane) raised in May 2008, triggered an in-depth investigation.
