TRENTON - New Jersey environmental officials say samples of air and milk show no sign of elevated radiation from the Japan nuclear disaster.

Environmental Protection Commissioner Bob Martin said yesterday that rainwater samples show trace amounts of Iodine-131, but not enough to cause any concern.

Martin was among five environment and security experts to testify at a briefing on nuclear power plant safety and emergency preparedness at the Statehouse.

New Jersey has four nuclear reactors, including Oyster Creek, the nation's oldest.

The review was prompted by the disaster unfolding in Japan after an earthquake and tsunami severely damaged four reactors there.

Two of Japan's damaged reactors are a design similar to Oyster Creek and Hope Creek in Salem County.

Lawmakers say the state must be prepared in case a disaster hits the Garden State.

Tests show normal radiation levels in NJAP wire services contributed to this report.
