BOSTON - Trace amounts of radioactive iodine linked to Japan's crippled nuclear power station have turned up in rainwater samples as far away as Massachusetts during the past week, state officials said on Sunday.

The low level of radioiodine-131 detected in precipitation at a sample location in Massachusetts is comparable to findings in California, Washington state and Pennsylvania and poses no threat to drinking supplies, public health officials said.

Air samples from the same location in Massachusetts have shown no detectable radiation.

The samples are being collected from more than 100 sites around the country that are part of the US Environmental Protection Agency's Radiation Network monitoring system.
