One major result of the Chernobyl accident that would cause as much agony to the incident was the spread of radiation. A definite effect of the spread of the radiation was the damage it had on the Eastern European agriculture. The EC (European Community) immediately put a 90 day ban on agricultural goods from Eastern Europe. This was initially thought of as political strategy from the US as well as other Western countries. This caused the Soviet Union to take the responsibility to pay for all the damage done to the Eastern European agriculture.

All the costs would eventually be analyzed in the short and long term by WHO (World Health Organization). The main factor that caused a lot of contamination and caused most of the European Countries to be concerned was the plume or cloud of smoke and debris that would travel through Europe. The countries that were affected the most are Eastern parts of Poland as well as parts of the FRG (Federal Republic of Germany). Most of the contamination was caused by the fallout from the plume as it went over Eastern Europe. Below is a diagram of the direction the plume took for the first few days and where it contaminated.
