Why the half-lives of most radioisotope is in the short range?

Question

Demonstrate your nuclear reaction balancing skills by answering the following three scenarios. You will fill the first nine blanks with either an integer numeral (1-3 digits), or the chemical symbol for an element (1-2 letters). For example, Curium has the chemical symbol Cm, and its most stable isotope has mass number A=247 and atomic number Z-96. (These are not answers to this question.) a) Identify the unknown daughter nucleus (?) in the following reaction: 1 ¹235U + ¼n → ¹3¹1 + (?) + 3 (√n) 92 53 Enter the mass number A = Enter the atomic number Z = Enter the chemical symbol: A N

As a health physicist, you are being consulted about a spill in a radiochemistry lab. The isotope spilled was 400 µCi of barium-131, which has a half-life of 12 days. (a) What mass of this radioisotope was spilled? (b) Your recommendation is to clear the lab until the radiation level has fallen 1 µCi. How long will the lab have to be closed?

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 =
