me."

International reports have shown conflicting views over the effects related to childbirth.

A resolution adopted in Kiev in 2003 referred to the risk of offspring with congenital and hereditary diseases among Chernobyl survivors living in contaminated areas, although another report initiated by the International Atomic Energy Agency said last September there was no evidence that low doses in contaminated areas caused any reproductive woes.

"I talked with my husband about having a child, but he said he wants me to focus on music now. Maybe later, I hope," Stepanyuk said.

Planning to continue pursuing her musical career in Japan, Stepanyuk added sadly, "I'm afraid that when I go back to Ukraine someday, my health will become worse again. Even returning one month for a holiday is tough for me. I don't think I can live in Kiev or in my village."

Yuri Scherbak, a former Ukrainian environment minister, said in a recent symposium on the Chernobyl accident in Tokyo that the disaster has had a "cumulative effect" on people's health, and "problems seem to increase rather than decrease as time passes."

About 5 million people live in contaminated areas of Belarus, Russia and Ukraine, and have continually been exposed to radioactive materials deposited in the ground and via intake of radionuclides from food, water and air.

Although many matters remain unresolved, Yukiko Mukai, chief secretary of the Tokyo-based Chernobyl Children's Fund, Japan, said the general relief funds, most of which are from individuals, dropped to 19.8 million yen in 2005 from 42.3 million yen in 2000.

"There are other disasters, including earthquakes or tsunami. The number shows that the Chernobyl accident does not have much urgency (anymore)," Mukai said, admitting such a tendency cannot be helped, considering the time that has passed since the accident.

Ryuichi Hirokawa, founder of the fund and a photojournalist who has been covering the Chernobyl issue, said during the Tokyo symposium that the 20th anniversary should not be used as an opportunity to draw a curtain on the issue.

"I don't think people have learned lessons from the Chernobyl tragedy. Twenty years have passed without us even clearly knowing how to take measures when the next disaster happens," he said.
