The Rincon Formation (or Rincon Shale) is a sedimentary geologic unit of Lower Miocene age, abundant in the coastal portions of southern Santa Barbara County, California eastward into Ventura County. Consisting of massive to poorly bedded shale , mudstone , and siltstone , it weathers readily to a rounded hilly topography with clayey, loamy ...
Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.
Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe. [1] Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2]
This increases the risk of harm, as the radon daughters can cause damage to lung tissue. [5] Radon and its daughters are, taken together, often the single largest contributor to an individual's background radiation dose, but due to local differences in geology, [6] the level of exposure to radon gas differs by location. A common source of ...

A view of Los Angeles covered in smog. Pollution in California relates to the degree of pollution in the air, water, and land of the U.S. state of California.Pollution is defined as the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or ...
This is a list of Superfund sites in California designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up ...
The plant supplies 6% of California's power, but carries a 1 in 37,000 chance of experiencing a Chernobyl-style nuclear meltdown within five years. Earthquake risks and rising costs: The price of ...
