Due to the experiments with nuclear materials at Lawrence Livermore Labs during the 1940's through the 1960's, and other nuclear construction and testing sites in California, high cancer rate probability have been recorded for all types of cancer diseases, cancer of the skin, cancer of the stomach, cancer of the prostrate, and other forms of cancer. The day-to-day and year-to-year background radiation in California is very close to that of what the background radiation was during the Chernobyl Accident inside the Chernobyl Nuclear Facility in Russia.
