"The fate of the country does not depend on how you vote at the polls -- the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot-box once a year, but on what kind of man you drop from your chamber into the street every morning." ~ Henry David Thoreau
But also released, notes the report, is radioactive material in the shale—including Radium-226 with a half-life of 1,600 years. A half-life is how long it takes for a radioactive substance to lose half its radiation. It is multiplied by between 10 and 20 to determine the “hazardous lifetime” of a radioactive material, how long it takes for it to lose its radioactivity. Thus Radium-226 remains radioactive for between 16,000 and 32,000 years.
