Lung cancer mortality rates

M = total mortality rate from lung cancer Mr = lung cancer mortality rate due to radon Mn = lung cancer mortality rate due to non-radon causes including smoking and all other factors, known or unknown r = average radon level in a county Then, from the linear-no threshold theory,... 

The first study was by Wang and MacMahon (10) and found a small increase in lung cancer mortality rates among a cohort of over 16,000 professional pesticide applicators. The updated report of the same cohort (11) confirmed an increase in lung cancer rates (SMR=1.35 90% Cl 1.14-1.58). The excess risk...

In the epidemiological literature related to cancer,one finds a continuing debate about the influence on cancer mortality rates, particularly on lung cancer of what has been termed the "urban factor" that is a sum of socio-economic conditions and environmental agents, present in urban but not in rural areas. (7, 4, 1, 40, 29,46, 41, 37, 39, 15). Nevertheless, up to now, there is no agreement as to the existence of a real excess of lung cancer mortality in...
