1. ABSTRACT

Suruhanjaya Komunikasi dan Multimedia Malaysia (SKMM) conducted an on-site RF

radiation measurement exercise at:

Perbadanan Kemajuan Negeri Melaka (PKNM), Menara MITC, Ayer Keroh,Melaka on 23rd Nov 2010

Upon concerns and request from Officer at PKNM.

2. OBJECTIVE

To determine the RF radiation level within the proximity of the telecommunicationstructure.

To ensure the RF radiation level complies with the Public Exposure Limit, inaccordance to Malaysias and international standards.

To assess the Health and Safety risks the telecommunication structure poses to thesurrounding community and residents, and to recommend the necessary action andmeasures based on the measurement outcome.

3. RF RADIATION PUBLIC EXPOSURE LIMIT

The exposure limit established by the International Commission for Non-Ionizing Radiation Protection (ICNIRP) is referred.

The exposure limit sets by ICNIRP is endorsed by the World Health Organization(WHO) and the Ministry Of Health Malaysia. Other countries that adopted the ICNIRPlimit include Australia, Singapore and the United Kingdom.

When measuring human exposure to RF radiation from communication towers andstructures, it is the norm to consider Power Density as it is more closely related tothe quantities in which restrictions on exposure are specified.

The limit value incorporates very large safety factors to protect the general public, including children. Further information can be obtained from http://www.icnirp.de.

4. SCOPE OF THE MEASUREMENT

The measurements assess the RF radiation emission from the directional and/oromni-directional antenna of the telecommunication structure in question.

In the presence of more than one telecommunication structure, the measurementoutcome indicates the cumulative RF radiation (for a given frequency range) from allstructures within the proximity.

Conclusion is derived from comparing the measured RF radiation level against thePublic Exposure Limit stipulated in Table 1.

5.MEASUREMENT EQUIPMENT

The measurement equipment in-use is the Rohde & Shwarze Portable EMFMeasurement System R&S TS-EMF (Figure 1). It measures a wide spectrum ofelectromagnetic fields (EMF) including RF in the environment and covers a broadfrequency range from 30 MHz to 3 GHz.

It complies with all common radio services which include:

2G Cellular 3G Cellular, Wireless Broadband Bluetooth Wi-Fi WiMAX FM Radio broadcasting TV broadcasting

The frequency-selective measurement determines the total radiation on a particularsite, and also permits assignment to specific radio services. All commonmeasurement methods and regulations are supported including the Europeanstandard prEN 50400.

The isotropic antenna is periodically calibrated to ensure accuracy.

10. CONCLUSION

Based on the investigations and measurements, it is concluded that thetelecommunication [tower(s)/structure(s)] comply with the Ministry of Housingand Local Government Guideline 2002, and the RF radiation level is well belowthe permitted Public Exposure Limit.

Therefore [it/they] pose(s) no health and safety risks to the surrounding

community and residents.

Below is the breakdown of the RF radiation level (in terms of Power Density) for agiven frequency range, against the Public Exposure Limit (as stipulated in Table 1):

Frequency range 900 MHz:

Average RF radiation level measured is 0.00062977653 W/m2. It is

0.014% below the permitted Public Exposure Limit.
