Induced by Alpha Particles Such as Those Emitted by Radon and Radon Progeny," 
Environmental Health Perspectives, September 1997.  "We have found that a 
relatively low dose of alpha-particles can result in the generation of 
extracellular factors, which, upon transfer to unexposed normal human cells, 
can cause excessive SCE [sister chromatid exchanges] to an extent equivalent 
to that observed when the cells are directly irradiated with the same 
irradiation dose."
