In 2015, the NCDC merged with two other federal environmental records agencies to become the National Centers for Environmental Information ...
Radon is also oxidised by dioxygen difluoride to RnF 2 at 173 K (−100 °C; −148 °F). [25] Radon oxides are among the few other reported compounds of radon; [29] only the trioxide (RnO 3) has been confirmed. [30] The higher fluorides RnF 4 and RnF 6 have been claimed [30] and are calculated to be stable, [31] but their identification is ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
In other nearby areas of Scotland (to the north of Aberdeen) and in Cornwall/Devon the radon is very much able to leave the rock. Radon is a decay product of radium which in turn is a decay product of uranium. Maps of average radon levels in houses are available, to assist in planning mitigation measures. [8]

This series was produced by the U.S. Army Map Service in the 1950s, prior to the maps in the larger-scale series, and consists of 489 sheets, each covering an area ranging from 8,218 square miles (21,285 km 2) at 30° north to 6,222 square miles (16,115 km 2) at 49° north. [30]
The largest natural contributor to public radiation dose is radon, a naturally occurring, radioactive gas found in soil and rock, [65] which comprises approximately 55% of the annual background dose. Radon gas levels vary by locality and the composition of the underlying soil and rocks.
