I see it every day. People suffering from the normalcy bias. Completely shutting out Japans meltdown as if it could never effect us, well that hasn't been the case. People should be advised to avoid anything that can concentrate air impurities such as a cars air filter without putting on a mask beforehand. Rain, as you will see here, also has the ability to concentrate the radioactivity in the air. By itself it is near harmless, unless you were unlucky enough to catch a hot particle, but once concentrated in a filter or rain, it can be hazardous. Of course this radiation would wash off of you skin with soap and water, but if ingested or taken into the body it could become harmful. Be warned!!!
