Although this does not answer your query, I thought it may be of general
interest:

Prof. Peter Smith and his team, based at the London School of Hygiene and
Tropical Medicine,
have conducted an epidemiological study of mortality and cancer rates in
plutonium workers at
the Sellafield nuclear installation - British Journal of Cancer 79(7/8)
1288-1301 (1999) this is
the March issue but it will be available mid February.  The study is based on
the analysis of
organ specific doses, from plutonium alpha emitters and plutonium 241, for more
than 5000
workers over a period of 40 years (1951 to 1990).
