apology re 'team 21'

[Slaback@micf.nist.gov]

My profuse apology.
My fingers again commanded without my mind being in gear.
I sent the 'Team 21' note to the wrong mailing list.
I guess all I can say is that RADSAFE comes first.

I hope doubling your unnecessary mailing with this
apology does not compound the sin.

Just to provide some benefit ....
did you know that the dose rate parallel to a line
source where the line source strength drops by 1/r^2,
drops as 1/r^3?  For example, if you put a point
source at one end of a pipe the dose rate 
produced by the radiation scattering off the inside
surfaces of the pipe goes as 1/r^3.

This is of significance to those using cold neutron
beams from research reactors.

A little risk adds spice to life.
