If there were 31 cases identified nationwide in the 10 years from 1990 to 1999 and then there are 60 cases diagnosed by A SINGLE RADIOLOGIST in 20 months from January 2015- August 2016, what am I missing?
I caught this story on PBS Newshour last week which offers some explanations (http://www.pbs.org/newshour/bb/rate-black-lung-disease-among-miners-may-10-times-higher-reported/): 1. limitations of government researchers combined with voluntary nature of miners getting x-rays amid their widespread belief that they may be penalized by employers for getting them, and 2. new mining processes that crush more quartz/silicon rock with the coal, which gets into their lungs.
