Radiation Dose from Tobacco Products

[William_Potvin_at_FLOWER@sev.org]

     In its Report No. 91, "Ionizing Radiation Exposure of the Population 
     of the United States", the NCRP briefly discusses the effective dose 
     equivalent resulting from the use of tobacco products.  They make an 
     estimate based on some data which is now nearly 20 years old, admit 
     that the effective dose equivalent is "impossible to estimate in the 
     present state of knowledge" and recommend further study.
     
     Can anyone direct me to more recent literature on this subject?
