LNT is believed to apply to radiation induced cancer for all forms of 
ionizing radiation including high LET neutron, proton, and alpha 
radiation by the ICRP, the NCRP, and the U.S. EPA.

The EPA published Federal Guidance Report #13 based on LNT 
calculations which pretends to give the cancer risks per Bq for just 
about every radionuclide to which someone might be exposed including 
alpha emitting radionuclides like Ra-226 and Pu-239. Remarkably, none 
of the risks estimates in FGR #13 is based on any actual data (such 
as the human radium studies).
