Industrial Radiography

I have found different exposure times for Cobalt 59 to become unstable (Co60) in a nuclear reactor from >4 days to years. Could anyone point to a reference to the exposure time.

Thank you in advance.

Hi Marshall,

Just come across your question and do not understand what you are asking. Do you want exposure times for Co60, or how long it takes for Co59 to become Co60 in a Nuclear Reactor, could you clarify your question so we on the forum may be able to answer you.

Regards,
