Post surgery psa, follow-up to Maldugs thread

I didn't want my question to get lost so I'm creating a new thread.  I was just reading maldugs post re first post-op PSA and I have a question.  He mentions that his post surgery PSA came in at 0.05 and his Urologist said that he may need to have follow-up radiation.  I thought the post surgery psa should be <.1 to be considered normal.  What are the factors that determine if radition is required as a follow-up protocol?  Is it the psa and margins?  What psa levels post surgery require follow-up treatment?

I'm in the dark here a bit , but <.0 (less than 0) = undtectable I had 4 results in that or the so called HAPPY range the last test was .1 and now has resulted in concern, follow up tests are required and if it holds at .1 or continues to advance forward then other options will be discussed as told by my surgen an oncologist will be consulted. ) :

54 PSA- 3.5
55 8
56 < 0,0,0,0,
57 .1
