With reports that a radiation plume from the Fukushima Daiichi nuclear plant could reach Southern California as soon as Friday, worried citizens have been hoarding potassium iodide pills, wondering if it's OK to go outside and otherwise fretting over an invisible, and somewhat unpredictable, threat. But all that worrying might cause more harm than the radiation itself, experts say. Here are some answers to common concerns. How much radiation do scientists think will arrive here?

A minuscule amount of radiation from the stricken Fukushima Daiichi nuclear reactor in Japan was detected in Sacramento but at such a low level that it posed no threat to human health, the U.S. Environmental Protection Agency said Friday afternoon. One station in Sacramento detected "minuscule quantities" of a radioactive isotope, xenon-133, that scientists said they believed came from the reactors at the stricken Fukushima plant.

After hearing emotional appeals to right "one of the great wrongs that we Americans committed against our own citizens," the House gave final congressional approval Thursday to legislation that compensates radiation victims of nuclear weapons testing and uranium mining.

A single dose of radiation during breast cancer surgery is as effective as three to six weeks of daily post-operative radiation for many women with early stage breast cancer, according to the first results from an ongoing study of more than 2,000 women. Most women undergoing a lumpectomy now have to visit a radiation center every weekday for at least three weeks following their surgery, a treatment that is, at best, inconvenient for working women and, at worst, debilitating for older ones.

If people weren't afraid of CT scans before now, it might just be a matter of time until they are. Or perhaps until lawmakers take matters into their own hands. L.A. Times staff writer Alan Zarembo wrote Tuesday of local hospitals that said they were simply following the manufacturer's recommendations: " Two More Hospitals Report CT Scan Radiation Overdoses ." Judith Graham wrote recently in the Chicago Tribune about attempts to protect children from excess radiation: " Clamping Down on CT Scans for Kids ."

Two California hospitals where patients were exposed to excessive levels of radiation during CT scans had programmed their scanners according to the manufacturer's specifications, officials at both hospitals said. Los Angeles County-USC Medical Center and Bakersfield Memorial Hospital are the latest additions to a list of California hospitals where overdoses occurred during CT brain perfusion scans. In both cases, the scanner in question was made by Toshiba. "We called Toshiba to give us the protocol," said Dr. Stephanie Hall, the chief medical officer at County-USC, where two patients received overdoses shortly after the hospital began doing the scans last fall.

China tried to quell panic buying of iodized salt Thursday after grocery stores across the country were emptied of the seasoning by hordes of people hoping to ward off radiation poisoning after the nuclear accidents in Japan. The clamor for salt reportedly started after rumors spread, possibly by cellphone text messaging, that China would be hit by a radioactive cloud from Japan's Fukushima No. 1 (Daiichi) nuclear plant, which had been badly damaged during last week's earthquake and tsunami.

Treating prostate cancer with radiation significantly increases the risk of developing colon cancer, researchers from the University of Minnesota reported this week in the journal Gastroenterology. Using federal data from 1973 to 1994, the researchers identified 30,552 men who received radiation treatment; 1,437 developed colorectal cancer, about 70% more than expected. The team noted that radiation treatment is highly effective for prostate cancer and should not be abandoned.

The Port of San Francisco has become the first West Coast seaport to install monitors that screen imported cargo for radiation emanating from nuclear devices, such as dirty bombs. Officials from U.S. Customs and Border Protection said they plan to install the radiation portal monitors at all seaports, land border ports and airports across the country. The two monitors, operated by customs officers, screen trucks as they exit the pier and turn red if they detect radiation.
