The purpose of this feature class is to show the radon potential where geologic conditions may contribute to an indoor radon hazard. The resolution of the RNILO data is 1:100,000-scale, while the scale of Sheet 1 is 1:750,000-scale. The intended use of both is at those scales and the information was prepared to not predict but assist agencies target their radon program activities and resources. Application of the data other than that is not advisable. This database can serve as a regional guide for identification of areas needing further indoor radon testing, and, through that, a basis for proactive decision-making. The unit descriptions and derivation methods can be found in the accompanying report. This feature class does not have any cartographic representations associated with its features. 20180101 Unknown Complete None planned -124.808648 -116.418518 46.303260 41.926900 Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Geology Radiation NASA Thesaurus List volume 1 radon radioactivity radium 226 uranium radium ISO 19115 Topic Category geoscientificinformation health environment ISO 19115 Topic Categories health environment geoscientificInformation Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Oregon Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus None REPORT DATA: This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.

All attribute columns contain missing data (Null) except REF_ID_CODE, MAP_UNIT_L, MAP_UNIT_N, TERRANE_GR, and FIN_RN_RNK: indoor radon test based on the factor's distribution throughout the state. Topology has not been checked or validated. Slivers, gaps, and overlaps are known to exist. OGDC-6 data was used as is, without alterations. Geology information was state-wide from OGDC-6 (Oregon Geology Data Compilation, release 6), with no areas of no data. Indoor air radon testing was primarily located in and around populated areas of the state. Aerial radiometric data was flown state-wide, with the exception of the southwest coastal region. Uranium mines obtained from the Mineral Information Layer for Oregon-Release 2 (MILO-2) were located in 72 geology polygons throughtout the state. Final radon rank attribute does not contain any unknown values. The resolution of the OGDC-6 geology datset is between 1:24,000 and 1:500,000.

This rank was based on a classification scheme of one (1), two (2), and three (3) representing geologic polygons with low radon potential, moderate radon potential, and high radon potential, respectively.

DOGAMI publications can be downloaded from http://www.oregongeology.org Each geologic polygon contained one or more factors. The most important factor contained in each polygon determined the polygon's final rank. The level of importance for determining radon potential rank, highest to lowest is as follows: uranium mine locations, mean indoor air radon test results, mean aerial radiometric measurements, and geologic material's uranium content.
