Half Life—9/6/11 Complete the following tasks on your own paper. Turn you paper over when completed. Define half-life. The half life for tritium (hydrogen-3) is 12.3 years. If you have 10.0g of tritium approximately how much will remain at the end of 28 200 years?
Half-life—9/8/11 Complete on your paper. The isotope neptunium-238 has a half-life of 2.0 days. If 4.0 g of neptunium-238 was produced on Monday of this week, how many grams will remain on Tuesday of next week? A sample of polonium-210 was purchased for your physics class on September 1st. Its rate of decay is 2 x 106βq. What kind of activity would be expected on June 1st of the following calendar year?
