The measurement of magnetic field intensity within Captain Elechi Amadi Polytechnic, Rumuola was carried out with the aid of a handheld Bentech (GM-3120) Model Electromagnetic Radiation Metre. A total of 6 sampled locations were recorded; randomly with six distinct measurement and their coordinates at each of the sampled location with the aid of the global system position satellite (GPS) device. The measurement took place between 2017 November to 2018 March. A minimum value of 0.3417 0.65 T was recorded at the Administrative Block and a maximum value of 1.9767 1.43 T at the Business Centre. The overall mean values of all the sampled locations all fall below the recommended limit for the outdoor magnetic field intensity exposure of 100T of the International Commission of Non-Ionizing Radiation Protection (ICNIRP). The outcome of the measurement reveals that the exposure to magnetic field intensity to staffs, students and commercial workers within the campus of the Captain Elechi Amadi Polytechnic poses no health hazard.

During the launch and return of a spacecraft, the intense combustion of propellants generates strong electromagnetic radiation, which interferes with the operation of electronic equipment in the spacecraft. To improve the electromagnetic compatibility of electronic equipment in spacecraft, it is necessary to study the electromagnetic radiation characteristics of rocket fuel. An electromagnetic radiation measurement system based on antennas is designed to measure the electromagnetic radiation generated by rocket fuel, and the electromagnetic radiation characteristics are obtained through data analysis. The mechanism of the electromagnetic radiation generated by rocket fuel is comprehensively analysed through the spatial, time-domain, frequency-domain, and energy-domain characteristics. A characterization model is established to provide a reliable scheme for evaluating the influence of rocket fuel electromagnetic radiation on electronic equipment in spacecraft.
