Outpatient clinics that perform diagnostic procedures using radioactive materials could do a better job of telling patients that they may set off radiation detectors at security checkpoints, a study shows. Information and documentation that these facilities provide to patients "varies widely" in terms of quality, said Armin Ansari, of the Centers for Disease Control and Prevention, who was involved in the study. "Some are extremely well done, some are not."

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.

Radiation from the largest solar flare in four years is expected to reach the Earth Thursday and Friday, potentially interfering with communication and navigation satellites and disrupting ground-based communication networks and power grids. The rain of charged particles from the so-called coronal mass ejections, or CMEs, should also enhance the northern lights, also known as the Aurora Borealis, making them both more prominent and visible farther south, perhaps even into the northern tier of the United States, experts said.

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. Photos: In Japan, life amid crisis But the level detected would result in a "dose rate approximately one-millionth of the dose rate that a person normally receives from rocks, bricks, the sun and other natural sources," according to an EPA statement.

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.

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.

NASA's Mars Odyssey spacecraft has confirmed that the radiation on Mars is so intense that it could endanger astronauts sent to explore the Red Planet, scientists said. Mars is bombarded by radiation from the galaxy at large, as well as by periodic bursts from the sun. The radiation would expose astronauts in orbit to an effective dose 2.5 times greater than that received in low Earth orbit. A three-year mission would expose astronauts to the career-long safety limit.

The New York City health department plans to spend about $1.4 million equipping hospitals with radiation detection devices in case terrorists detonate a radioactive bomb. The equipment, largely paid for with federal grants, could help medical centers diagnose the thousands of people who would flood hospitals after such an attack, the department said. The devices would go to public and private hospitals, officials said.
