AW: [ RadSafe ] Mango's Tooth Fairy Sr Radiochemistry

Wed Jul 4 11:03:04 CDT 2007

Sorry, John, but distorting the name "Mangano" to "Mango" is in my
perception unacceptable and an insult, though you might know that I do not
agree with his agenda. 

I hope this was an error.

Erik,
Of course explaining your concerns, which would cast
doubt on the TFP, might be hard to explain to the
public.  Nevertheless, I believe the public can
understand the problems with the TFP, excluding the
minorite that are already convinced.  I would include
those who may have had a child with cancer and need a
reason behind the cancer, like a local nuclear power
plant.
