Re: Radioactive dose from smoking

[Dave Derenzo <dave@uic.edu>]

NCRP 95 states in section 3.2.1 that a 30 cigarette a day smoker receives a 
dose of 0.8 to 1.0 rad per year to small areas of the bronchial epithelium 
at segmental bifurcations.  They apply a quality factor of 20 and estimate 
an annual dose equivalent of 16 rem (160 mSv).  Applying a tissue weighting 
factor of 0.8 to the effected part of the lung, an effective dose 
equivalent of 1,300 mrem (13 mSv) is estimated.  They go on to say that 
they question the value of the quality and weighting factors and they do 
not wish to use it to make an actual estimate of dose equivalent or ede.
