The South Coast Air Quality Management District announced none of their radiation monitors were reporting increased levels due to Japan's earthquake and tsunami.
The e-mail was sent to NBC LA shortly after 5 p.m.
"Based on monitoring of radiation at Southland sites, officials have not detected any increase in radiation levels above typical background levels since last week’s earthquake and tsunami in Japan.
"The South Coast Air Quality Management District is posting daily updates of monitored radiation levels on its website at www.aqmd.gov," the e-mail noted.
During a press conference earlier Friday, Mayor Antonio Villaraigosa sought to ease fears over Radiation dangers.
“Los Angeles has one of the most aggressive emergency management systems in place with highly trained responders and one of the most prolific, state-of-the-art Emergency Operations Centers in the country,” he said.
During the briefing, Dr. Lucy Jones, an expert in geophysics and seismology at Caltech, reiterated there was no danger.
"There is no immediate threat in Los Angeles; however, now is the time to examine our ability to respond to a crisis and to recognize where our vulnerabilities lie," she said.
The mayor also announced new city directives that will increase Los Angeles' emergency and disaster preparedness, including a new partnership between the City of Los Angeles and the Federal Emergency Management Agency (FEMA).
