EPA: Radioactive Iodine Exceeding Maximum Contaminant Levels for Drinking Water Found in Pennsylvania and Massachusetts ... But It's Safe

Washington's Blog

As I noted Tuesday, the government is responding to the Japanese nuclear accident by trying to raise acceptable radiation levels and pretending that radiation is good for us.

Forbes' blogger Jeff McMahon points out:

The Environmental Protection Agency yesterday reported finding elevated levels of iodine-131, a product of nuclear fission, in rainwater in Pennsylvania and Massachusetts. The levels exceed the maximum contaminant level (MCL) permitted in drinking water, but EPA continues to assure the public there is no need for alarm:

“It is important to note that the corresponding MCL for iodine-131 was calculated based on long-term chronic exposures over the course of a lifetime – 70 years. The levels seen in rainwater are expected to be relatively short in duration,” the agency states in a FAQ that accompanied yesterday’s brief news release.

“In both cases these are levels above the normal background levels historically reported in these areas.”

EPA said it is receiving “verbal reports” of higher levels of radiation in rainwater samples from other states as well, and that Americans should continue to expect short-term contamination of rainwater as radioactive isotopes spread through the atmosphere from Japan.

“We continue to expect similar reports from state agencies and others across the nation given the nature and duration of the Japanese nuclear incident.”

The EPA also found radioactive iodine in milk in Washington State.

Fortunately. the half life of radioactive iodine is only 8.02 days. That means that the iodine loses half of its radioactivity within 8 days.

If you trust the EPA to tell you if radiation levels are unsafe, then carry on.

But if you do not trust the government to tell you the truth, and if you are afraid of radioactive exposure, you might consider stocking up on a little extra milk and water, and then letting each container of fluids sit for a couple of weeks on a shelf or in your refrigerator before drinking. That will greatly reduce the radioactivity caused by the iodine 131...[Full Article]
