44. From Rutherford'sscattering experiment of alpha particles it can be concluded that 1) Most of the alpha particles were deflected through angels greater than 90° after interaction 2) The direction of most alpha particles is reversed after interaction with gold nuclei. 3) the spaces between gold nuclei are relatively large compared to the size of the nuclei.

The purpose of producing 99Mo (usually by neutron activation of natural molybdenum, as in the preceding problem) is to produce 99mTc. Using the rules, verily that the decay of 99Mo produces 99mTc. (Most 99mTc nuclei produced in this decay are left in a metastable excited state denoted 99mTc.)
(a) Calculate the number of grams of deuterium in an 80.000L 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+2H3He+n. (c) Could the neutrons be used to create 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.
(a) Calculate the radius of 58Ni, one of the most tightly bound stable nuclei. (b) What is the ratio of the radius of 58Ni to that at 258Ha, one of the largest nuclei ever made? Note that the radius of the largest nucleus is still much smaller than ?le size of an atom.
The RBE for lowenergy s is 1.7, whereas that for higher-energy s is only 1. Explain why, considering how the range of radiation depends on its energy.
One half the rays from 99mTc are absorbed by a 0.170mmthick lead shielding. Half of the rays that pass through the first layer of lead are absorbed in a second layer of equal thickness. What thickness of lead will absorb all but one in 1000 of these rays?
To obtain the most precise value of BE from the equation BE=[ZM(1H)+Nmn]c2m(AX)c2, we should take into account the binding energy of the electrons in the neutral atoms. Will doing this produce a larger or smaller value for BE? Why is this effect usually negligible?
Ionizing radiation interacts with matter by scattering from electrons and nuclei in the substance. Based on the law of conservation of momentum and energy, explain why electrons tend to absorb more energy than nuclei in these interactions.
A radiationenhanced nuclear weapon (or neutron bomb) can have a smaller total yield and still produce more prompt radiation than a conventional nuclear bomb. This allows the use of neutron bombs to kill nearby advancing enemy forces with radiation without blowing up your own forces with the blast. For a 0.500kT radiationenhanced weapon and a 1.00kT conventional nuclear bomb: (a) Compare the blast yields. (b) Compare the prompt radiation yields.
Why is the number of neutrons greater than the number of protons in stable nuclei that have an A greater than about 40? Why is this effect more pronounced for the heaviest nuclei?
Consider Figure 10.12. If the magnetic field is replaced by ail electric field pointed in toward the page, in which directions will the a,+,and rays bend? Figure 10.12 The effect of a magnetic field on alpha ( a ), beta ( ), and gamma ( ) radiation. This figure is a schematic only. The relative paths of the particles depend on then masses and initial kinetic energies.
Integrated Concepts Estimate the density of a nucleus by calculating the density of a proton, taking it to be a sphere 1.2 fm in diameter. Compare your result with the value estimated in this chapter.
