RE: Radiation Hormesis

[John Jacobus <crispy_bird@YAHOO.COM>]

Dr. Luckey gave a presentation that I attended where

he claimed that the incidences of cancer were

increasing during the last century aecause we reducing

radiation exposure.  My comment was if changes in life

expectancy considered.  In 1900, the life expectancy

was 45 years.  In 2000, it was 73 years.  If you look

at the statistics, the risks of breast and prostate

cancers increase as one ages.
