TRENTON - Air and water samples show no sign of radiation in New Jersey from the damaged Fukushima nuclear plant complex in Japan.

The state environmental protection department says the tests show normal radioactivity levels through yesterday.

DEP officials say samples were recently collected over the weekend. The DEP says it will increase sampling to twice a week.

The Environmental Protection Agency monitors the air for radiation at its offices in Edison. Levels were reportedly normal as of yesterday.

Tests in Pennsylvania and Massachusetts have detected very low levels of radiation in their rainwater.
