Level of Electromagnetic Radiation Emitted from Mobile Phone Base Station during F1 Race in the Kingdom of Bahrain

Measuring the power density of the Electromagnetic Radiation (EMR), or Radio frequency radiation, emitted from the mobile base station (transmitting mast) during three days event of Formula 1 Race in 4th, 5th and 6th April 2008 at Bahrain International Circuit, Kingdom of Bahrain, revealed that the exposure to EMR is much lower than the allowable limit set by several professional organization (seven organizations); it represents less than 0.1%. The instantaneous recorded power density at distances 160 m, 230 m and 300 m from the transmitting mast were, on average, 46.5 µW/m 2 , 86.8 µW/m 2 , 395.8 µW/m 2 , respectively. The highest recorded instantons power density during the whole event was 901 µW/m 2 and was on Sunday afternoon of 6 th April 2008, where it was the winner announcing day. The long- term recorded power density during this international event shows lots of variation during this 90 minutes recording in last day (Sunday) of the event which is winner announcement event. This indicates that F1 spectators do substantial number of phone calls during the events where the variation in this day was from 0.607 µW/m 2 to 16.832 µW/m 2 while in Saturday was from 0.313 µW/m 2 to 5.455 µW/m 2 and in Friday was from 0.139 µW/m 2 to 2.356 µW/m 2 .
