Earthquake/Radiation Monitoring Sources
First, do NOT panic! We simply don't know enough yet to accurately determine what kind of threat, if any, we're dealing with. Be aware, gather information, but do not let fear control you! For those so inclined these sites offer constantly updated information:
Baseline Surface Radiation Network:
"Because of the important role radiation plays in the climate system, the Baseline Surface Radiation Network (BSRN) was established to provide a worldwide network to continuously measure radiative fluxes at the Earth's surface. Many of these stations began operation in 1992 and each year more stations are added to the network. These stations provide data for the calibration of the GEWEX Surface Radiation Budget (SRB) Project and other satellite-based measurements of radiative fluxes. BSRN data are also used to validate radiative flux models. About 40 stations in contrasting climatic zones, covering a latitude range from 80°N to 90°S (see station maps) are providing data to the BSRN archive located at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany. In 2004, BSRN was designated as the global surface radiation network for the Global Climate Observing System (GCOS). The BSRN stations also contribute to the Global Atmospheric Watch (GAW)."

“WARNING: Radiation Fear-Mongering And Health”
by Karl Denninger
"If, and I stress if, there is a reason to attempt to protect your thyroid against radioactive iodine exposure only Potassium Iodide should be used. NOT, I repeat NOT, Potassium Iodate. They are not the same chemical. The first is FDA approved for this purpose, the second is not. In an emergency situation you can also paint iodine solution (the topical stuff that is used on cuts and such) on your trunk and get some degree of protection. The latter must NEVER be ingested as it is a poison. There is no solid evidence of how well painted-on iodine will actually work, but it's better than nothing if it's all you have."
