- Dear sci.physics types,
-
- I have not caught this thread from the beginning, but there is
- a notable series of experiments done on young mammals and other
- animals who were fed cobalt-60 irradiated food. The young developed
- a statistically higher percentage of some cellular disorder called
- <now I'm not sure of the spelling or pronunciation> hyperplasia
- in which the cells just grew bigger instead of dividing.
-
- I believe the study was done by a female doctor from India
- but memory fades here. There was a bit on it on local TV
- a few years ago. I believe the study was repeated, and it
- could not be demonstrated that the effect was bogus, nor could
- it be proven by large enough statistics (how _do_ you get data
- like that on human babies?) that the effect was applicable to
- human babies. Seems like there was no effect on any
- adults of any species, if I remember correctly.
-
- Has anyone repeated these tests with *microwaved* food instead
- of gamma-irradiated food???
