Nufer & Associates undertake the investigation electromagnetic radiation across the whole spectrum, from ELF (extra low frequency) to microwave fields.

We undertake this work with full reference to Australian and overseas standards including current Australian legislation from ACMA, standards and recommendations of ARPANSA, WHO, and other organisations including ACIF.

The scope of our consultancy extends through the following aspects of this technology and include –

• Power Systems 50 Hz (ELF/EMF) - Powerlines, Transformers, & Cabling:
• Radio Transmitters (EMR/EME) - Multi-transmitter & Multi-Frequency Sites:
• High Power Radiation Impacts from RADAR & HF Transmitters:
• Product Electromagnetic Compatibility Issues:
• Environmental Impact Assessments for Real Estate Development:
• Workplace Health & Safety (in the light of the ABC Toowong Experience):
• EMR/EMF Microwave,  Training;
• EMC - Product design & Pre-compliance test;
• EMI Assessments on Electromagnetic Interference:
• HERF - Hazard of electromagnetic radiation to fuel vapour;
• HERP - Hazard of electromagnetic radiation to personnel;
• Occupational Hazard Non-Ionising RF Radiation Awareness Seminars;
• 50Hz ELF Power Radiation Planning Considerations Seminars.

As current flows through an electric wire, it generates a magnetic field around itself. This is the field of concern with regard to human health, and is usually contained by running the to and from circuits in the same cable or in close proximity.

In the case of appliances these conductors are often separated for a number of reasons, resulting in quite high fields in the immediate vicinity of the appliance as shown below.

Electrical power is used for nearly everything we have in our home and work environments and includes. For the most it is safe and operates well below the limits set by the authorities. Typical levels of radiation around the home include:

# Some devices also produce electromagnetic fields on radio frequencies.

1. Radiation fields are cumulative in that working in a kitchen where there are a number of active appliances may result in field contributions from a number of appliances (including lighting) according to its radiation characteristics and distance.

2. In addition to 50 Hz emissions some appliances such as microwave ovens, televisions (older CRT)  produce electromagnetic fields at radio frequencies also. These come under the a different set of measurement guidelines and standards.

3. Nufer & Associates provides the following services in respect of electromagnetic emissions from 50 Hz power infrastructure:

• Measurement of radiation from any 50 Hz mains infrastructure;
• Correlation of data against Australian/overseas standards;
• Compilation of data for evidentiary purposes;
• Recommendations regarding mitigation against 50Hz radiation;
• Management of implementation steps to limit exposure;
• Ongoing monitoring services;
• Public information evenings (free).

4. A significant amount of work in this area concerns the radiation from powerlines in new residential areas.

Whilst many of these installations are undertaken with great care, there has recently been concerns of secondary effects such as the breakdown of pollution gasses by corona discharge into ions which then get ingested by nearby residents and animals.
