[ RadSafe ] AW: Chernobyl's Reduced Impact helps establish Threshold

Howard:

 

Your guesstimates are reasonable and probably are biased towards the
safe side.
I doubt whether a more substantial discussion is presently possible

 

Regards, Rainer

Betreff: Chernobyl's Reduced Impact helps establish Threshold


Threshold levels I nominate to start the discussion:
Radon ---  4pCi/l (c148 Bq/cu meter) in bedroom air -
           confluence of the B Cohen and W Field studies
Acute exposure --- 10rem (c rad)
           Breast cancer-bomb studies
Chronic exposure --- 10rem/year
           Taiwan apt, NSWS, Karala etc
Infants, pregnancy, etc might be lower,
 
Arthritis and limited area threhold is higher 
      (where more benefit may balance harm).
 
Beware the alien "Spamfighter" using my address.
