Webb10 aug. 2024 · Therefore, a long half life indicates fast radioactive decay while a short half life indicates a slow radioactive day. The half life of some substances cannot be determined since it may take millions of years to undergo radioactive decay. Conclusion. Radioactive decay is the process where unstable isotopes undergo decay through …
WebbChlorine has two stable isotopes (35 Cl and 37 Cl), as well as a slow-decaying isotope between them which facilitates neutron absorption by 35 Cl. Chlorides permit fast breeder reactors to be constructed. Much less research has … This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days, and years. Current methods make it difficult to measure half-lives between approximately 10 and 10 seconds.
