This shiny application calculates the exposure to non ionizing radiation due to a cellular base station operating in the 1.800 MHz frequency band. The calculation is based on the paper "The Design and Development of an App to Compute Exposure to Electromagnetic Fields" (DOI: 10.1109/MAP.2017.2655527).

The model implemented in this assignment has some simplifications for the antenna model (it considers omnidirectional antennas with maximum transmiting power). So, the result is very conservative and represents an upper bound value for the true exposure. So, if the calculated exposure ratio is x%, then the true value is lower than x%.

Input: There are only two:

1. The base station height
2. The probe height

Output: The application will calculate the exposure ratio for a probe with the given height due to the base station and show a plot for the distances between both from 10 meters to 100 meters.

To be considered safe according to the ICNIRP limits, the total exposure ratio should be less than 100%. Remember: this is a very conservative calculation. Actually, the correct result will be some orders of magnitude below the calculated in this assignment.
