Radio frequency radiation measurement for base tower station safety compliances: a case study in Pulau Pinang Malaysia

The residence of Pulau Pinang and Malaysia generally are worried with the possible health effects due to Base Tower Station (BTS) radiation. Particularly, the residents of Pulau Pinang are utilizing their mobile phones for multiple kind of tasks including communications, browsing the internet and other applications. With the recent advances in mobile communication technologies, the end user demanded a better coverage, great communication services, and faster speed for internet browsing. To fulfill the demand, service provider and communication companies are providing plenty of communication base tower leading to the beliefs of that the tower emitted radiation and cause harmful effect to human health and voiced out and complain to the municipal councils in Malaysia. In this paper, a measurement was conducted to study electromagnetic fields (EMF) radiation level in Pulau Pinang. The measurement is compared with the international standard provided by International Commission of Non-Ionizing Radiation Protection (ICNIRP). Far field measurement of different values of long term evolution (LTE) exposure was demonstrated in radiofrequency (RF) shielded environment. LTE850, LTE1800 and LTE2600 field exposure was compared in term of its’ electrical field and power density that adhere to the standard provided by ICNIRP.

Risk Assessment Model for Railway Passengers on a Crowded Platform

The purpose of this study is to develop a risk assessment measure to provide an understanding of the safety of railway station platforms. We estimated the number of accidents on a platform in a year. It was influenced by the factors such as the design, equipment, and the profile of the station users. Consequently, 16 factors were defined, such as the platform design and passenger movement. Poisson regression and negative binomial regression models were employed to estimate and analyze the number of accidents from a station database containing 158 platforms from 52 stations in Japan. The results show that the number of accidents is related to the length of the narrow part of a platform, the width of the gap between the platform and train, the curvature of the platform, passenger flow crossing, the number of trains passing and stopping, and the audio and visual announcements concerning approaching trains. We expect that this result will allow railway companies to identify weaknesses in station safety and subsequently set priorities for investments in safety. Furthermore, administrative authorities can evaluate the safety performances of railway companies, and consider subsidies for investments in safety.

ASSETS OF MODEL METRO STATION AND THEIR CRITICALITY

The paper deals with the identification of protected assets in the model metro station, which is a part of critical infrastructure in Praha; and with the identification of their criticality. A metro station is used by a lot of people and it involves many expensive components and devices with interdependences which form a system of systems. The system, its components and fittings are very vulnerable to damages from disasters of many kinds. The first step of ensuring metro station safety is the identification of basic metro assets which are important for safe metro operation and for human (employee and passengers) security and environment safety; and the other is determination of criticalities of considered assets with taking into account all relevant sources of hazards. These facts are input data for further processes which are important for safe metro operation under the different conditions.
