Debate is over - mistatements of fact

[epirad@mchsi.com]

Dr. Cohen,



In your past email, you had several obvious mistatements of fact.  



On the NCRP Committee (you requested to review your work), it is my 

understanding - 



There is one Epidemiologist 

There is one Biostatistician

There is one Physicist

and a member or two of the NCRP who are not epidemiologists, but rather HPs 

including a president of the NCRP.



You stated, the "NCRP Committee is dominated by Epidemiologists"?



Would you mind documenting your statment by providing the names and expertises 

of the NCRP committee members you met with to discuss your work?



In addition, you are not correct in stating (once again by the way) that 

Epidemiologists are only accustomed to using well standardized approaches 

designed to determine dose-response relationships, and my work does not fall 

into that category.



You are correct that your work can not determine a dose response, but you are 

misleading people by suggesting either Epidemiologist do not perform studies 

that do not assess a dose response (eg Ecologic) or suggesting ecologic 

studies do not fall into the realm of epidemiology.   



Epidemiologist have the expertise to review your ecologic studies. Please 

provide examples of physicist that have performed ecologic studies.  

Epidemiologist perform them, but unlike you, use them to formulate hypotheses 

not test them.

Search ecologic study on the web and let me know how many you find performed 

by Physicist.



These were my first hits when I searched using Google- The fourth one provides 

a nice summary of ecologic studies.
