A chain reaction can produce self-sustained fission if each fission produces enough neutrons to induce at least one more fission. Thyroid ultrasonography can confirm the presence of a thyroid nodule. A-chopped celery B-died tomatoes C-sliced cucumbers D-shredded carrots. 1 1,000g Alarmed scientists, many of whom fled Nazi Germany, decided to take action. A. One fission will produce two atoms, the next round of fission will create four atoms, the third round eight atoms, and so on. The nuclei of other heavy elements, such as thorium and protactinium, also were shown to be fissionable with fast neutrons; and other particles, such as fast protons, deuterons, and alphas, along with gamma rays, proved to be effective in inducing the reaction. 1 Additionally, some nuclides are easier to make fission than others. Note that the first two reactions must occur twice for the third to be possible, so the cycle consumes six protons ( Control rods help prevent overheating, perhaps even a meltdown or explosive disassembly. Of course, not all applications of nuclear physics are as destructive as the weapons described above. 235 238 In fact, for fusion to occur for elements of greater mass than iron, energy must be added to the system!
