Scenarios approach to the electromagnetic exposure: the case study of a train compartment.

Paffi A, Apollonio F, Pinto R, Liberti M - Biomed Res Int (2015)

Bottom Line: Previous studies identified the train compartment as the place where people can experience the highest exposure levels (still below the international guideline limits) to electromagnetic fields in the radiofrequency range.Here a possible scenario of a train compartment has been reproduced and characterized, both numerically and experimentally.A good agreement between the simulated electric field distributions and measurements has been found.

ABSTRACT
Previous studies identified the train compartment as the place where people can experience the highest exposure levels (still below the international guideline limits) to electromagnetic fields in the radiofrequency range. Here a possible scenario of a train compartment has been reproduced and characterized, both numerically and experimentally. A good agreement between the simulated electric field distributions and measurements has been found. Results indicate that the higher values of exposure in specific positions inside the train compartment depend on the number of active cell phones, the bad coverage condition, the cell orientation, and the presence of metallic walls. This study shows that the proposed approach, based on the scenarios characterization, may efficiently support the assessment of the individual electromagnetic exposure.

Mentions: This behavior is even more evident considering the /E/ field distributions on the planes y = 80 cm (Figure 5(a)) and y = 120 cm (Figure 5(b)) coming from numerical simulations with the cell phones in the vertical configuration.
