Web5 apr. 2024 · A nuclear chain reaction is a series of fission reactions. A nuclear fission reaction is the process of releasing a neutron from an unstable atomic nucleus. When this released neutron interacts with another unstable isotope, the new isotope also undergoes nuclear fission, releasing another neutron. Similarly, a chain of reactions takes place. WebUltrahigh–dose rate FLASH radiotherapy (FLASH-RT) is a potentially paradigm-shifting treatment modality that holds the promise of expanding the therapeutic index for nearly any cancer.

What is a chain reaction? Let's start at the beginning. The primary active ingredient in the fuel for a nuclear reactor is a particular variety, or "isotope," of uranium, called U235. U235 is relatively rare — only about 0.7% of uranium as it exists in nature is U235.
