WASHINGTON (AP) — A spike in radioactive sulfur from the damaged Japanese nuclear plant was detected in California in late March, but researchers say it posed no threat to health.

While the amount was higher than normal background levels, it was still small, said Mark Thiemens of the University of California, San Diego.

“The levels we recorded aren’t a concern for human health. In fact, it took sensitive instruments, measuring radioactive decay for hours after lengthy collection of the particles to precisely measure the amount of radiation,” said Thiemens. He is lead author of a report on the findings being published in Tuesday’s edition of the Proceedings of the National Academy of Sciences.

Japan’s Fukushima nuclear plant was damaged in a tsunami on March 11 and extremely low amounts of radioactive iodine later showed up in milk sampled in California, Colorado, Connecticut and Massachusetts over the following weeks. Environmental Protection Agency officials said the levels were so minuscule they were not harmful to public health. EPA scaled back its monitoring efforts to routine levels in May.

The new report focused on sulfur measurements taken at Scripps Institution of Oceanography in La Jolla, Calif., March 28-April 1.

While there was no threat from the radiation, Thiemens explained in an email that tracking the sulfur helps researchers understand the movement of particles in the atmosphere.

    LIES!!! Don’t fall for this scam!!! The EPA is just trying to justify its existence!

    They are finding high radiation levels in the rainwater in the Pacific Northwest; and just recently- in early August – in the rainwater in Oklahoma City and and Southeast Colorado. Lake Louise in Canada also has very high levels of radiation. It is everywhere to some extent and it is ongoing. We are not being told the truth by our officials. Much information is coming from independent researchers. Stay out of the rain and don’t put your trust in the govt. telling you the truth.

    Why report this, if it doesn’t exist? LIES

    Total lies and one day (very soon) when Sacramento citizens find out how badly they were lied to-it is going to be awful.

    If anyone would like to correct Mr.Theimens about his error here is how you can:

    I don’t put any trust in what the EPA has to say!! I agree with all the comments above! Why tell us anything if there is nothing wrong? The jet stream goes from Japan to Candada and Alaska and on down to the western states, and more.
