Radiation safety implications of 131I treatment in a patient with Grave's disease undergoing home hemodialysis.

abstract：:Correlations are studied between average radon levels in 1600 U.S. counties and mortality rates in them from various types of cancer. By far the strongest correlation is with lung cancer, but the sign of the correlation is negative. When smoking prevalence is included in a multiple regression, the large negative corre...
