WASHINGTON — Radiation exposure took Alice Broudy's husband a generation ago.

This week, a court ruling sliced away at her bid for redress.

In a quiet ruling that nonetheless resonates nationwide, a federal appellate court rejected efforts by Broudy and others seeking claims on behalf of "atomic veterans," exposed to radiation during nuclear tests and in post-war Japan. The same court simultaneously rejected bids by other veterans exposed to biological and chemical agents.

Taken together, the dual rulings by the D.C. Circuit Court of Appeals will likely impede many veterans hoping for compensation. At the very least, it will complicate future claims.

"It's a significant ruling," Washington-based attorney David Cynamon, who represented veterans in both cases, said Friday. "Unfortunately, it's a significantly bad ruling."

A Department of Veterans Affairs spokesman couldn't be reached to comment.

Broudy, a resident of California's Orange County, has long been seeking full compensation for the death of her husband, a Marine major who was repeatedly exposed to radiation. She has company.

George Woodward, who lives north of Wichita, Kan., in the town of Miltonvale, was exposed to radiation during a 1955 test blast. Kathy Jacobovitch, a resident of Vashon Island, Wash., lost her father through exposure to contaminated ships in Puget Sound. Ernest Kirchmann, a 62-year-old Navy veteran who lives south of Minneapolis in tiny West Concord, who's filed a separate lawsuit, was exposed during a 1964 nuclear submarine accident.

"It isn't just my personal case," Broudy said Friday. "It's the entire veterans community. It makes me so angry."

Broudy married her husband, Charles, in 1948. Three years earlier, he'd walked the war-poisoned streets of Nagasaki. Within a decade, he was facing radiation in the Nevada desert. He died of lymphatic cancer in 1977. Though she has since received partial compensation, Broudy has been confronting the federal government for more. She has now lost three separate lawsuits.

"This closes the door," Cynamon said of the latest appellate court ruling, which was issued Wednesday. "It will make it very difficult, if not impossible, for individuals who are victimized by government cover-ups."

All told, an estimated 220,000 U.S. soldiers were allegedly exposed to radiation in the 1940s and 1950s. Some, such as William Yurdyga of Sacramento, Calif., claimed in an earlier lawsuit that they were exposed following the Hiroshima or Nagasaki atomic blast. Others claimed exposure during Cold War testing.
