- The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample is measured to be 0.58 times the Carbon-14 activity of living plants. What is the age of the sample in years? (The half-life of the Carbon-14 isotope is 5730 years.)How could an element emit alpha and beta particles and result in the same element?The isotope iodine -131 has a half-life of 8 days. If an individual is injected with 100 mg of iodine-131 today, how much will remain in his body after 24 days? (assuming that none is lost through normal body channels? Time (days) Amount (mg) Today 100 mg
- The isotope cesium-137, which has a half-life of 30 years, is a product of nuclear power plants. Show that it will take 120 years for this isotope to decay to about one- sixteenth its original amount.7. Which kind of nuclear reaction is shown in the equation below? 92 U +o n -4 Ba + Kr + 3n+ 200MEV 56 nuclear fission nuclear fusionWhen thorium (atomic number 90) decays by emitting an alpha particle, what is the atomic number of the resulting nucleus?
- what type of energy holds the nucleus together?Plutonium is especially hazardous when inhaled or ingested because it emits alpha particles. Why do alpha particles cause more damage to tissue than beta particles when their source is inside the body?An air bubble frozen in ice is extracted from many meters below the surface in the arctic. The sample of air is found to have an activity per gram of carbon that 0.8% that of air today. About how long ago was this pocket of air frozen? 35,000 years ago 40,000 years ago 46,000 years ago 52,000 years ago 58,000 years ago
