Investigate The Biological Effects Of Electromagnetic Pulse Dose Study And Safety Standards

With growing concern being expressed that exposure to electromagnetic fields (EMF) may cause various health effects, the EMF Project has been established by many countries to determine if there were adverse health effects that could result which need to be addressed. Globalization of trade and the rapid increasing of mobile telecommunications worldwide have caused the WHO's (the World Health Organization) focus attention on the large differences existing in the EMF exposure standards performed by different institutions. The increasing evidence from the electromagnetic pulse (EMP) non-thermal bioeffects suggested that the safety assessment based on energy absorption is questionable.The results from EMP non-thermal bioeffects experiments ( the EMP affect cell proliferation experiments and the EMP affect cell membrane fluidity experiments) and from the simulation of 3D human body model exposed to EMP with frequency-dependence time-domain finite-difference ((FD)2TD) method showed that the EMP bioeffects could be remarkable though the absorbed energy is far below the existing safety limit.The Sepcific electric impulse (SEI) is introduced as a new expresser of EMP radiation dosimetry. Comparing with the Specific absorption (SA) and the Specific absorption rate (SAR), the SEI may be more reasonable for described the EMP bioeffects. The basal characters of the transmembrane voltage in a simplified cell model were studied and the change of the transmemebrane voltage when exposure to EMP were analyzed. It indicated that the SEI-caused-transmembrane voltage change may be one of the EMP bioeffects mechanisms.
