RF HAZARD METER TEST FACILITY |
|
Telstra has appointed EMC Systems (a subsidiary of EMC Technologies) as the exclusive distributor of a Portable RF Hazard Meter Test Facility. This unique RF Hazard Test Facility was especially developed by Telecom Research Laboratories for the on site testing of RF Hazard detection probes used to measure the level of RF incidental radiation emitted by transmitting antenna systems such as those used for Radiocommunications, radio and TV broadcast, microwave repeaters, GSM and AMPS mobile phone base stations. It has been recognised for a long time that exposure of the human body to high levels of electromagnetic radiation may lead to adverse health effects.

".....fault with the meter could place the operator or nearby persons in a hazardous situation as the misleading faulty meter reading.....
.....may inadvertently result in exposure to potentially hazardous electromagnetic fields."

EMC Systems are proud to be the sole distributors of the
Portable RadHaz Meter Test Facility
developed by Telecom Research Laboratories.

|
To ensure the protection of personnel working on site and members of the general public, it is essential that the levels of RF radiation around these transmitter installations is known when determining compliance with
AS2772.1:1990
|
Safe working practices involve the routine surveying of these antenna installations and the surrounding areas where the electromagnetic radiation may be radiated at significant levels. The surveys quantify the level of radiation using a range of portable RF hazard meters. These meters are used on a day to day basis by staff working at these installations in order to assess their personal exposure levels. The failure rate of these RADHAZ meters has been particularly high and is generally a consequence of the fragile nature of the instruments and the environment they are used in. These faults have included drops in sensitivity and isotropicity of the RADHAZ probe such that it indicates a very low field strength even when it is exposed to high and potentially hazardous fields. Any such fault with the meter could place the operator or nearby persons in a hazardous situation as the misleading faulty meter reading may inadvertently result in exposure to potentially hazardous electromagnetic fields.

As a site survey is designed to locate all areas exceeding the AS2772 maximum exposure level in order to restrict access to those areas, incorrect survey results could lead to staff over exposure on a regular or continuing basis. The accuracy and credibility of the results is therefore of paramount importance.
|
The credibility of survey results is dramatically improved if the RADHAZ meter is tested immediately before and after each use. To ensure that all RADHAZ meters are fully operational, Telecom Research laboratories developed this inexpensive TEM cell designed specifically to test the operation of the most common RADHAZ probes including Narda, Raham and Holaday. Housed in a robust attractive carry case, the unit comprises an RF source, transverse electromagnetic (TEM) cell and an RF power meter. Operating from 12 VDC, it is compatible with most vehicle cigarette lighter outlets making it particularly useful for use at sites where mains power is not available. The units offer test field strength accuracy of 0.5 dB and isotropic response error of 0.5 dB.

RF RADHAZ and EMR
NATA ACCREDITATION for AS/NZS 2772
EMC Technologies has gained NATA accreditation for the measurement of Electromagnetic Radiation (EMR) in accordance with AS/NZS2772.1:1998. EMR (also known as non-ionising radiation) is generated by radio and television broadcast stations, mobile phones and base stations, microwave repeaters, and various industrial, medical and scientific devices. It is known that exposure of the human body to high levels of EMR may lead to adverse health effects. To ensure the protection of personnel in the workplace and to protect members of the general public, it is essential that the EMR levels around these EMR sources must comply with the limits set by AS/NZS 2772.1. “Radio Frequency Radiation: Maximum Exposure Levels, 3 kHz to 300 GHz.” The Australian Communication Authority has advised that this standard will be mandated and progressively phased in for a wide range of EMR devices as of 1 January 1999 The C-tick and A-tick labelling provisions will also apply.
Safe working practices involve the routine surveying of areas such as antenna installations, surrounding areas where high EMR levels may occur. The site survey is designed to locate all areas which exceed the AS/NZS 2772 maximum exposure level in order to restrict access to those areas. The accuracy and credibility of the results is therefore of paramount importance. An accredited NATA test ensures accurate and competent measurements providing all the data necessary in order to prevent accidental over-exposure of workers and the public. Virtually all RF transmitter devices will fall under the scope of the imminent ACA regulations.
- Radiocommunications and Telecommunications equipment
- Mobile phones and mobile phone base stations and towers
- TV and radio broadcast transmitters
- Land Mobile , CB transmitters, Amateur Equipment
- VHF/UHF paging, Telemetry, Paging and Emergency Services
- Microwave repeaters, Radar
- Baby monitors, Cordless Phones, remote control devices
- Industrial RF welders, RF heaters, induction cookers and similar equipment
- Medical diathermy, surgical and other devices using or generating RF
Owners and operators of licence telecommunications facilities will need to maintain compliance with AS/NZS2772.1 as a condition of the licence.
Manufacturers and importers will be responsible for the compliance of devices within the scope of the regulation.
Broadband, narrowband and pulsed RF measurements are performed over the range 9 kHz to 18 GHz. Comprehensive spectrum plots are provided
clearly identifying the frequency and level of all significant EMR sources. NATA endorsed reports may be used to label and signpost the
facilities into “go/no-go” areas and to alert people to the potential risk of exposure to high EMR levels. EMC Technologies NATA reports
will be acceptable to the ACA as proof of compliance.
