OCCUPATIONAL AND ACCIDENTAL LXPOSURE 



Table 1 



Effects on all subjects 



It was not possible to estimate accurately the doses received but approxi- 

 mate calculations have been made by the staff of the Cancer Institute — 

 Dr. Martin and Miss McRae and by the late Dr. C. E. Eddy. These with 

 the corresponding values for Index 1 are shown in Table 2. These results 

 suggest a rough inverse relationship between dosages and the values of 

 Index 1.
