No measurable radiation in Southern California from failed Japanese reactors, federal officials say
Federal officials with access to radiation monitoring said Friday they had not seen any signs of radioactivity in Southern California related to the Japanese nuclear crisis.
A United Nations forecast had predicted the radioactive plume from failed Japanese reactors would drift across the Pacific by Friday.
Forecasters explained the plume would lose radioactive force as it traveled and would probably not be detectable by the time it reached Southern California.
The projection made by the Comprehensive Test Ban Treaty Organization in Vienna is based on patterns of Pacific winds and provided no information about actual radiation levels. It is likely to change if the weather shifts over the next few days.
The U.S. Environmental Protection Agency operates 124 air monitors across the nation that provide hourly readings of radiation levels. Twelve are 12 stationed in California, including Los Angeles, Riverside, Anaheim, San Bernardino and San Diego.
