The relationship between average indoor levels of radon and lung cancer mortality in the counties of Cornwall and Devon, England, are investigated. The associations of population density, social-class distribution, and regional smoking prevalence with lung cancer mortality in the local-authority districts of England and Wales were estimated by regression analysis. Low rates of lung cancer in Cornwall and Devon were predicted from the relationship. The differences between observed and predicted mortality in Cornwall and Devon districts were compared with average indoor levels of radon, which varied considerably between districts. Residual variations in lung cancer mortality were not significantly correlated with average indoor radon measurements. The current advice of the National Radiological Protection Board to government is to concentrate radon measurements, remedial action, and preventive action principally on Cornwall and Devon, but cross-sectional geographical data do not support the hypothesis that raised levels of radon indoors in southwest England have an important effect on lung cancer mortality.

We analyze the relationship between the lung cancer mortality and the indoor radon intensity from the viewpoint of nonlinear mathematics. We conclude that their relationship is governed by the proportionality law where the cumulative lung cancer mortality Y is negatively proportional to the cumulative radon intensity X; or specifically, the nonlinear change of nonlinear face value (qYu – qY) is negatively proportional to the nonlinear change of nonlinear face value (X – Xb). The author obtained a set of data from late Professor Cohen on the lung-cancer mortality rate versus indoor radon level collected from 1,597 counties and territory of the USA. We initially presented the data as various primitive elementary graphs; then extended them to the primary graphs, leading graphs, and the proportionality graphs. The article emphasizes the building of a straight-line proportionality relationship for the dose-response data in a log-linear and/or log-log graphs. It demonstrates a straightforward methodology for solving the key upper asymptotes (Yu) for the proportionality equation using the Microsoft Excel via determining the “coefficient of determination”. (Note: q = log, Yu = upper asymptote of Y, Xb = bottom asymptote of X)

Cancer, responsible for about 1 death in 5 in Scotland, cost over £1 per head of population in 1965 and led to bed occupation of almost 2,000 bed years. Time lag (symptoms-doctor-hospital-treatment) is usuallv small. Age distribution is as in other European countries. Excluding accidents, cancer is the second most important cause of death in children. In relation to other countries Scotland's position is very poor and the lung cancer mortality in both sexes is the highest known. Lung cancer is the most important in males, breast cancer in females. Alimentary cancers come second in both sexes. In this century alimentary cancers increased till the thirties or forties and then declined. Cancers of pancreas, cervix uteri, ovary, prostate, kidney and bladder, together with leukaemia, have all increased. Cancer of the lung has increased elevenfold in women and fiftyfold in men. It now accounts for 9 to 12 per cent of all male deaths in cities and large towns
