Everywhere I read says the complete inventory of noble gases was released from the reactors in the early phase of the accident.

But if so, why does Kr-85 still linger in unit 2?
Recent measurements at inlet of Unit 2 PCV Gas Control System:
28 March 2012 : 73 Bq/cm3
03 April 2012: 97 Bq/cm3

Could it be an effect of continuing fuel damage?
