Chlorine is used to purify graphite during manufacture, in a reactor the 
residual chlorine becomes activated to Cl-36. The T/2 is 301 thousand years.

Anyone here know the origin of Cl-36 in graphite wastes from old 
(decommissioned) graphite-moderated reactors ?
Reportedly, the graphite contains an activity of roughly 1 MBq/kg from 
Cl-36.

Thanks in advance.
