AQMD Offers Daily Upates on Radiation Risk

You have probably heard news reports about harmful radiation escaping from damaged nuclear power plants in Japan following the recent tsunami. Some have even voiced concern that this radiation could travel across the ocean and impact California. There is no increased risk of harmful levels of radiation exposure in the United States, based on the situation to date and a review of actual monitored levels by AQMD as well as other public health officials and technical experts.

The South Coast Air Quality Management District, your local air pollution agency, has operated radiation monitors for several years for the U.S. Environmental Protection Agency (EPA). AQMD monitors radiation levels at three sites in Southern California and sends the radiation measurements every hour to EPA. The California Department of Public Health also operates an additional radiation monitor in Southern California.

Starting today, you can get a daily update regarding levels of radiation in Southern California at AQMD’s website at Monitors operated by AQMD/EPA will detect any change in outdoor radiation levels.

Further general information on EPA’s radiation monitoring network can be found at The U.S. Nuclear Regulatory Commission’s response to the situation can be found at

Monitoring radiation is a very small part of the many activities AQMD does to protect public health and clean the air that we breathe. For more information on how you can help clean the air, go to .

The Actors' Gang


  1. Thanks so much for this! I haven’t been fretting, but I do understand why people are concerned and am glad to have a source of real information.

  2. Actually, you go to the AQMD website and radiation monitoring is nowhere in sight. All the links lead to the EPA’s page, where they have been withholding data on their measurements for weeks.

    There are no measurements for Southern California that I have been able to find online (and believe me, I have been looking for hours and hours days on end).

    If someone can point me to updated readings, that would be great.

    But until then, this claim that the AQMD is monitoring sites for daily updates on radiation readings is, as far as I’m concerned, completely false.
