North American Scientific Inc. has received FDA approval to market its second-generation iodine-125 brachytherapy radiation source for treating prostate cancer, the North Hollywood-based company said. The company has filed for patent protection for the enhanced drug, which will be marketed by Mentor Corp. under the trade name IoGold. In February, North American Scientific announced FDA approval of its initial source design, also marketed by Mentor Corp.

The Environmental Protection Agency conceded that the air many Americans have been breathing since the Chernobyl nuclear accident may have had three times the radiation the agency reported. But even at the higher readings, the radiation is still not hazardous to human health, EPA said Monday. The discrepancy occurred because most EPA equipment was only measuring airborne particles of radioactive iodine-131.

The plant at the center of Japan's worst nuclear accident kept pumping small amounts of radiation into the air for more than a week before officials discovered it, the facility's operator said. Radioactive iodine-131 at double the legal limit was detected Friday at a ventilator opening in the building, but officials waited until three days later to turn off the exhaust fan and seal the opening. The ventilator had been left running after the Sept.

Radioactivity reaching the United States from the Chernobyl nuclear accident has declined so much that the Environmental Protection Agency said today it will stop reporting radioactivity concentrations at the end of this week. The agency's daily report on behalf of the interagency task force monitoring Chernobyl developments said that only 12 out of 26 rain samples analyzed by EPA monitoring stations contained iodine-131 and average concentrations were continuing to fall.

Although heartened by Gail Devers' gold-medal comeback in the women's 100-meter race, physicians specializing in thyroid conditions say they are perplexed and disturbed by her account of her battle against Graves' disease. Some of the pieces, they say, just don't compute. In particular, they say it is virtually impossible that the radioactive iodine she took to quell her overactive thyroid caused her feet to become so swollen and inflamed that doctors considered cutting them off.

The United States has picked up its first ground-level radioactivity from the Chernobyl nuclear accident, the special interagency task force monitoring developments of the accident said today. The task force said in a statement that a rainwater sample collected Monday at Richland, Wash., measured 500 picocuries per liter of iodine-131, according to a laboratory report. "This level poses no danger to residents in the area," the statement said.

Radioactive gases leaked from a Russian nuclear reactor early today, and an official described the accident as serious. Yuri Rogozhin, spokesman for the state nuclear inspectorate Gosatomnadzor, said: "The degree of the incident is serious, with possible consequences for the environment and the population." He said radioactive iodine had leaked from the plant at Sosnovy Bor, 60 miles from St. Petersburg.

A draft report that estimated 11,000 people died from cancers related to nuclear testing during the Cold War was well done and should be published, the National Research Council said Tuesday. The study, by the Centers for Disease Control and Prevention and the National Cancer Institute, concluded that radioactive fallout from Cold War nuclear testing exposed virtually everyone in the United States to radiation and contributed to the cancer deaths.
