The Hiroshima High Court ruled Wednesday that 84 people in Hiroshima are eligible to receive state health care benefits even though they were exposed to radioactive "black rain" following the 1945 U.S. atomic bombing outside an area currently recognized by the government.

Upholding a lower court decision last year, the court ruled in favor of the plaintiffs, saying they should receive the same benefits as those provided to atomic bomb survivors who were in the zone where the state recognized that black rain fell.

The high court ruling is expected to impact the ongoing review by the central government on areas where black rain fell and its health impact.
