摘要：
Groundwater samples were collected from eight wells in remote Antelope
Creek valley, Idaho. Seven out of eight locations showed that groundwater
222Rn concentrations were much greater than 11 Bq/L (300 pCi/L),
a maximum contaminant level (MCL) proposed by United States Environmental
Protection Agency (USEPA).
Rock and soil samples collected near the sampling wells revealed
that 238U contents were between 0.55 to 6.41 ppm. Minerals collected
from different regions of the country with similar 238U contents
also showed high concentrations of 222Rn in the groundwater. An
interpretation technique using a Geographic Information System (GIS)
software with available information also indicated a clear correlation
between the rock types and 222Rn concentrations in the groundwater.
Several cancer rates near the study area reported to be higher than
national average. Many factors can be affecting 222Rn in the groundwater,
what may these factors be in the study area and if the 222Rn concentration
is a contributing factor to certain high cancer rates in the area
remain to be subjects of interest.
