HONOLULU -- Another fire broke out at the fourth reactor at the Fukushima Daiichi Power Plant in Japan on Tuesday, heightening concerns for even more radiation release.

Fear for nuclear fallout is running high in Hawaii, but the state Department of Health said there is no radiation hazard and the department continues to monitor air quality around the clock.

A Rad Net system sits on the roof of the fifth floor of the state Department of Health office. The department has been using the device for the past 20 years. The system measures air quality and will indicate if something unusual is detected in the air.

"We're in constant contact with our federal partners, so everybody's gearing up for this, the information is streaming to us, as soon as their getting we're getting it," said Lynn Nakasone, Department Of Health.

The department said it considers the risk for radiation exposure from Japan to be highly unlikely but are prepared to take action if a hazardous scenario were to surface.

"We would have options in place for the public, we would have shelters in place, provide potassium iodine pills if needed, they're would be tons of information provided," Nakasone said.
