RE: estimates of human-human irradiations

["Lieskovsky, Miro" <MLieskovsky@nbpower.com>]

Kim,
A quickie using MicroShield:

Source: 7kBq of K-40 in a sphere (water) with a 30cm DIA.

The exposure rate at 100cm from the sphere centre is ~1.2E-5mR/h, that's
0.012microR/h or ~1000times less than environmental exposure rates. At 30cm
from the sphere centre it is ~1.4E-4mR/h. 

  :-)  However, I think, that a person standing in my
'too-close-for-comfort' zone shields off more radiation than s/he
contributes.  Next time I hug my wife, I'll have a gamma meter on me....   

Regards,

Miro

Hi

I don't want to start an instoppable thread-- but has anybody 
computed how much irradiation we get from standing by others, due to 
our natural concentrations of radionuclides?  Any other similar 
comparisons?
