Lungile, a radio-pharmacist based at iThemba LABS, measures the activity of a specific isotope with a Geiger counter and it shows 200 counts per minute at 12h00. At 15h00, Lungile notices a huge decrease in activity and the the Geiger counter now only records 25 counts per minute. NOW Use the counts/minute to determine the half-life of this radioactive isotope? FULLY EXPLAIN your choice under the RATIONALE section below! A. 3 hours B. 8 hours C. 1 hour D. 2 hours

I am specifically having difficulty in solving part d of this problem. a) Calculate the number of grams of deuterium in a 54,300 L swimming pool, given deuterium is 0.0150% of natural hydrogen. (b) Find the energy released in joules if this deuterium is fused via the reaction 2H + 2H → 3He + n. (c) Could the neutrons be used to release more energy? (d) Discuss the amount of this type of energy in a swimming pool as compared to that in, say, a gallon of gasoline, also taking into consideration that water is far more abundant. (Enter the ratio of the energy in the deuterium in the pool to the energy in a gallon of gasoline. The energy in a gallon of gasoline is 1.2 ✕ 108 J.) Edeuterium Egasoline =
Suppose that instead of using half-life to characterize the radioactivity of elements, we used the idea of third-life (that is, the time it takes for one-third of a sample to decay). If the half-life of Uranium 235 is 700 million years, what would its third-life be?
I asked this question once and the answer returned was correct, but I couldn't follow the work so I'm hoping you can write it more clearly: A proposed nuclear reactor facility will have an electrical power output of 805 MW with a 30.2% efficiency in converting nuclear to electrical power. Assuming the average fission reaction produces 227 MeV, how many reactions will take place at the facility every second?
