A Radiological Survey of Washington DC

In mid-January 2009, in advance of the inauguration of President Obama, a radiological survey of downtown Washington, DC was conducted at the request of the Secret Service.

No statistically significant man-made radiological activity was detected in the survey.  Typical variations in natural background radiation were found, along with slightly elevated readings at the National World War II Memorial and elsewhere “caused by the building materials containing naturally occurring radioisotopes.”
