Ketjureaktio
Ketjureaktio is the Finnish term for a chain reaction, defined as a sequence of chemical or nuclear steps in which reactive intermediates produced in one step propagate the process by generating more intermediates, allowing the reaction to continue with little or no external input. A chain reaction proceeds through distinct stages and terminates when the reactive intermediates are removed or neutralized.
In nuclear physics, a chain reaction occurs when neutrons released by fission induce further fission in neighboring
In chemistry, chain reactions involve reactive intermediates such as free radicals or ions. Initiation creates these
Key concepts include chain carriers (radicals or neutrons), chain length (average number of propagation steps), and
