subject recived this intake in 1964 as a nuclear chemical operator with DOE  in 1987 subect retired for the last 9 years his deep dose was 120 each mth. worker was assigned office duty and was not working in a rad zone.
what can be the long term health effects to the worker he still has the transit in his lungs and a slive of PU in his thumb. subject in 85 years old left hanford when he was 58. starting to show signs of parkinson and has asthma problems since he retired.  what will this do to a workers lungs plus working in the tank farms in the 70's

It would appear that an elevated chance of lung cancer may occur, based on the 50 year CEDE of 420Rem.

In most parts of the world living a relatively healthy life until you're 85 would be a heck of an accomplishment. Looks like he has skirted effects for almost fifty years. Whatever elevated probability he might have had would now be overshadowed by common age related facators.

The 420 appears to be CDE not CEDE!

My apology, and thanks to the great seer of HP.  I accidentally mistyped (very bad move, I know) the extra E this AM.  Can't believe I did that.  But, I was thinking that the dose to the lung would be from the Pu and not the AM.  My understanding is that Am gets taken up by bone more than Pu, and the biological half life is quite short compared to Pu, so that the CDE of 420 Rem must be from the Pu.  Since this is a significant increase in dose over the "threshold" for estimating the risk of cancer increasing from Pu I felt that there would be an elevated chance of occurence. 
Again, my bad and a most sincere apology for switching up the CDE and CEDE acronyms.

the worker  was still working in mixed field for over ten years  after this incident . my question who belives he was over expsoed?
And the wound is from a broken  item of pure PU in his thumb they could not  recover. the item is still emebed in his thumb
