RE: Hormesis markers in population around NPP??
Jim,
Since you asked, here are some comments.
Do they have dosimetry measurements or just locations on the face of the
earth? How far apart were these plants? What do they mean by one exposure
unit? One mSv, one mile? What about other types of facilities, like
factories, or farms? What about health and nutrition? How long have the
individuals lived in the location and what do are their occupations. And,
most important, how healthy are the individuals?

Friends,
FYI. Comments? Let me know if you can review the paper? Let me know if
you don't have it.

power plants.

Abstract
Information about hematopoieses as a result of exposure to very low
levels of radiation is scarce. To investigate the human hematopoietic
effect of very low level radiation exposure, measurements of peripheral
blood components were performed among 3602 men and women, aged 35 and
above, living in a community near two nuclear power installations in
Chinshan, Taiwan. The radiation level that each individual was exposed
to was represented by a surrogate level, '1 / D1^2 + 1 / D2^2,', a
transformed distance from each individual's residence to the two power
plants D1 and D2. In addition to comparing average hematology
measurements, multiple regression analyses were done to include age,
gender, smoking, drinking status and the surrogate radiation exposure
level as independent variables. Univariate and bivariate analyses showed
that the hematology measurements had significant associations with age,
gender, smoking or drinking. The multiple regression analyses revealed
that significant positive associations with '1 / D1^2 + 1 / D2^2,' were
found for hemoglobin, hematocrit, platelet, white blood cell and red
blood cell. The platelet count might increase for 208.7 x 10^3/microl if
the exposure from the nuclear plants increased by one exposure unit.
This type of association implies that those who lived closer to the
nuclear power installation had a higher blood cell count; we suspect
that this could be a type of radiation hormesis.
