Radiation Readings in the U.S.

A Conelrad production, this site has been created for private citizens of the U.S. (mostly) with geiger counters to post their geiger measurements in response to the ongoing nuclear threat at Fukushima Daiichi, Japan.

* CORRECTION: the 10/28 ambient was 00.116 µSv/hr
  (Sorry! I accidentally posted the sample reading.)

This ambient reading was subtracted from today’s
sample reading, which was either collected using
the “charged wire” method developed in 1908-1915
or using the filter from a 5 cubic meter air draw.

* Today’s sample had a persistent half-life.
