Sign in to saveAlso known as Cl-36, 36Cl
Chlorine-36 (36Cl) is a radioactive isotope of chlorine whose half-life is 301,000 years; it decays primarily (98%) by beta-minus decay to 36Ar, and the balance by electron capture to 36S. This cosmogenic isotope occurs in natural chlorine alongside the two stable isotopes.

Chlorine-36 (36Cl) is a radioactive isotope of chlorine whose half-life is 301,000 years; it decays primarily (98%) by beta-minus decay to 36Ar, and the balance by electron capture to 36S. This cosmogenic isotope occurs in natural chlorine alongside the two stable isotopes.
Trace amounts of radioactive 36Cl exist in the environment, in a ratio of about to 1 with respect to the stable chlorine isotopes. This 36Cl/Cl ratio is sometimes abbreviated as R36Cl. This corresponds to a concentration of approximately .
