Re: multiple myeloma
RADSAFERS,
One of my school texts , "The Leukemias: Etiology,
Pathophysiology, and Treatment , J,Rebuck et al, lists three known causes
of leukemia, they are heredity, benzol, and ionizing radiations. According
to this text, spontaneous Myeloid leukemia is considered to be a disease of
the middle span of life, and while it is more prevalent in the affluent
than the poor, and in Caucasians more than any other race, it affects males
and females equally. As most of you know, in Japan after Hiroshima and
Nagasaki there was a peak incidence of leukemia in 1950 - 1952. Of the 92
cases (at that time), 39 were myeloid leukemia and only 1 was chronic
lymphatic leukemia - the remainder were acute and subacute leukemias.
Not too many years ago, San Onofre Generating station had a former
NRC inspector sue the station - her lawyers maintained that her exposure at
the plant (I forget now, but I believe it was under 100 mrem) was
responsible for her contracting the disease - even though it occurs
spontaneously in the worlds population and statistically seems to run in
some families. Perhaps one of them subscribed to RADSAFE can help out my
recollections...
